The recording and playback levels can be set using the sliders in the Recording and Playback meter toolbars:
The slider with the microphone icon sets the recording volume on a system level. If the operating system is prohibiting this action, this slider will be inactive.
The slider with the speaker icon sets the playback volume relative to the system volume. It does not affect the volume of exported files, use the gain sliders on each track to edit those.
Best practice: Before starting to record, click on the microphone icon and select Start Monitoring to activate the recording level meter. If it enters the yellow or red area (-9 dB to 0 dB) when testing with a normal volume, lower the recording level to prevent clipping and distortions in the real recording.
If you selected 1 (Mono) Recording Channel on the Audio Setup > Recording Channels the meter will only display the level on the Left channel
There are two ways to get your work out of Audacity: Saving the project, and exporting audio.
You can save projects using the File > Save Project menu. A saved project (.aup3) has the most information about your project available, but can only be opened in Audacity. There are three options available, each useful for a different use case:
Save Project (Ctrl+S
/Cmd+S
) will save your current project. If you save for the first time, you may need to specify where to save it to.
Save Project As... will save your project in a new place and continue editing on it, should you want the original project to remain untouched.
Backup Project... will save the current state of the project in a new file, but won't switch to it.
Warning: Avoid saving active projects on external drives, USB sticks, or network storage. Audacity requires fast, uninterrupted access to your storage when recording and editing.
You can export your project into an audio file using the File > Export menu. Exported audio (.mp3, .wav, .ogg, and more) can be opened with a wide variety of programs, and uploaded to some social media, but may have worse quality and lose some Audacity-specific information.
In the File > Export menu, you'll see a few different options:
Note: You may need to install FFMPEG to access some of these options.
Export as MP3, Export as WAV and Export as OGG will export your project into the selected format.
Export Audio... (Ctrl+Shift+E
/Cmd+Shift+E
) will provide you options to export to more uncommon formats, such as FLAC, M4A, AC3, WMA, AMR, MP2 and custom FFMPEG exports.
Export Selected Audio... will export only the current selection time range, instead of the entire project.
Export Multiple... (Ctrl+Shift+L
/Cmd+Shift+L
) will let you export different parts of the audio based on either tracks or labels.
Caution: Muted tracks are not exported. What you hear when playing in Audacity is what will be exported.
There are also two additional options which export non-audio data:
Export Labels... will export labels if you have any.
Export MIDI... will export the currently selected note track as a MIDI or Allegro file. You can only export one note track at a time.
Removing background noise is core to most audio cleanup operations. Audacity has several tools to aid in this.
Best Practice: While it's possible to rescue an otherwise unusable file with noise reduction techniques, your recording will sound best if you take steps to ensure a noise-free environment before recording.
The Noise Reduction effect works best to remove a constant source of noise, like the hiss of fans, the hum of fridges, or whines, whistles and buzzes.
To use it, use the following steps:
Locate a section of your recording that's just your background noise, preferably a few seconds long, and select it.
Go to Effects > Noise Reduction and press the "Get noise profile" button.
Select all the audio for which you want to reduce the noise.
Go to Effects > Noise Reduction again. You now can tweak the settings of the reduction to your liking. Tip: While tuning the settings, use the "Residue" toggle to hear what sound will be removed.
Once you're satisfied with the result, click OK to apply it to the selected audio. Note: If you used the Residue toggle before, make sure to switch it back to Reduce before pressing OK.
Tips:
If you set the sensitivity too low, or use a noise profile that doesn't properly represent the noise throughout your track, you may experience artifacts (random bursts of very short tones).
If you don't need to tweak the settings after setting the noise profile, you can press Ctrl+R
/Cmd+R
to immediately apply the effect to your selection.
The Noise Gate effect attenuates any sound quieter than a certain threshold while leaving sounds louder completely unaffected. To use it
Select a part of the audio that's just background noise.
Go to Effects > Noise Gate... to open the effect.
Click Select Function: Analyse Noise Level and press OK. Audacity will now tell you where your noise level lies and recommending a threshold.
Select the audio you want to apply the effect to.
Go back into Effects > Noise Gate..., set it back to Select Function: Gate, and enter the threshold level from earlier.
Tweak the other parameters as sound best to you.
Press OK to apply the noise gate.
Best practice: Use the noise gate after applying noise reduction. This way, you can use less aggressive noise reduction settings, which may grant you a cleaner end result.
The notch filter removes a hum or whistle at a specific frequency. To use it:
Select the audio you want to apply the effect on
Go to Effects > Notch Filter to open the effect.
Enter the frequency you want to reduce, together with the Q-value (how many frequencies around the main one you want it to affect - the higher the number, the less frequencies).
Press OK to apply the effect.
Tips:
The "Mains hum" of the electricity grid is 60Hz in north and middle America, and 50Hz in most other countries.
Use Analyze > Plot Spectrum... to find the offending frequency if you're not sure where it is.
Sounds often have harmonics or overtones. They are at a multiple of the main frequency, so for a 50Hz sound, you may need to apply the notch filter as well at 100Hz, 150Hz, and so on to remove it fully.
This page is an introduction tutorial to editing in Audacity. It covers how to import files, making cuts, rearranging clips, and applying effects!
To start editing, you need some sort of sound to edit. You can either record some sound, or import an existing sound file (for example, an MP3 or WAV) by dragging & dropping it into the project window. You can also import files via the File > Import menus.
Note: To import proprietary file formats such as M4A or WMA, you need to install FFMPEG first.
Once you have that, you will see a waveform of your sound:
This waveform is a visual representation of the song. The larger the blue "blob" is, the louder the section. Lines standing alone ("spikes") indicate sudden and short loud sections such as clicks, snaps, claps and drum hits. With a bit of practice, you can use the waveform to quickly find your way around an audio file.
To remove a section of an audio file, first select the section by clicking and dragging in the waveform.
Once you have a selection, press Delete
or Backspace
to delete it.
Audacity supports clips, which are pieces of audio inside the project which can be moved independently. Technically, any audio you record or import already exists as a clip, denoted by the rounded clip handle bars above the waveform.
You can click + drag on the clip handle bar to move a clip around.
To split a clip into two independent clips,
Click into the waveform where you want to split the clip.
Tip: To make precise adjustments, zoom in first.
Right-click > Split Clip (Ctrl+I
/ Cmd+I
)
Note: If you select some audio instead, it will create a clip out of the selection.
To trim a clip, hover with your cursor around the upper third of the left or right edge of a clip:
Then click and drag the edge to trim the clip to it's desired length.
Note: Trimming is a non-destructive operation. You can un-trim a clip at any time. If you have created your clip by splitting up a larger clip, you can even un-trim the current clip until it's at the length of the old clip. If you want to permanently remove the trimmed data, you can copy the clip to another project, choose Selected audio only when pasting, and move it back.
Audacity supports a wide range of effects and effect plugins. These effects can be used for Noise reduction & removal and more, and while each effect does different things, they all generally can be applied in the following way:
Select the audio you want to apply the effect to.
Go to the Effect menu.
Select the effect you want to use. Typically, a window like this will open:
Tweak the effect to your liking. You can click the Preview button to hear a short sample before applying it to the whole selection.
Press OK to apply the effect.
Best practice: If you want to apply an effect to an entire track, use realtime effects instead. By doing so, you can change the effect at any point later on.

Punch-in repair of recordings is an easy and fast way to fix short sections of a recording by re-recording it.
Best Practice:
Make sure that Overdubbing is turned on in Transport > Transport Options.
Make sure that your latency settings are correct.
If your audio recording broke and you immediately noticed it (for example because you misspoke your script or had to cough), it is possible to stop the recording and immediately fix the mistake by using Punch-and-roll recording. To use it:
Record as normal until you make the mistake.
Stop the recording.
Choose a splicing point by clicking into the audio before the mistake happens. For spoken content, this should be between words so you can drop in easier. Note: All audio on the track after the splicing point will be deleted.
Start a Punch-and-roll recording with Transport > Recording > Punch and roll record (Shift+D
). This will playback a couple of seconds of your recording so you can find the right rhythm and tone as before, and at the splicing point you set in step 3, it will switch to recording mode and make a crossfade.
From here on out you can continue recording as usual. If you make the same mistake again, you can stop the recording and undo (Ctrl+Z / Cmd+Z) and try again. If you make another mistake later on, you can do another Punch and Roll recording by repeating the steps above.
Tip: You can change the amount of pre-roll audio and crossfade in the Preferences > Recording in the Punch and Roll recording section.
If your audio recording broke at one specific point in time (for example because an ambulance drove by), but you only notice it after having recorded everything, it is possible to re-record this section using punch-in repair.
Best Practice:
Make sure that Overdubbing is turned on and Software Playthrough is turned off. Both settings can be found in Transport > Transport Options
Always create a backup of your project before editing it. For a continuous recording, this typically is best done by #exporting-audio.
To use it:
Select a couple of seconds of audio before and after the bad part. With overdubbing turned on, recording will playback the recording back to you and help you match the timing.
Do the re-recording on a new track. To do this, Shift-click the record button or press Shift+R
. It will automatically start recording from the beginning of your selection.
To hide the cut a bit better, a crossfade may help: Making crossfades
If your new take is slightly longer or shorter than the gap left in the original recording, you can split the clip: #splitting-up-clips
You can use a similar technique to continuously fix mistakes as they occur during a recording session using Latency Compensation
Audacity can record various types of microphones and other audio devices.
You can connect your mic by plugging it into the appropriate port. In general, this means:
If you have a USB mic, plug it into a USB port.
If you have a mic with a 3.5mm jack, plug it into a mic-in port.
If you have an XLR mic, plug it into an XLR-USB audio interface and the interface into the USB port.
The exact details depend on both your exact computer model and your microphone model. Please see their respective manuals or support pages for further information. You may need adapters if your computer is missing appropriate ports.
Note: Many Laptops and Notebooks feature built-in microphones. While they may be good enough to record your voice to an intelligible standard, the recordings they produce tend to be somewhat unpleasant to listen to.
Select the microphone to record from the list of available recording devices in the Audio Setup toolbar
You may see some unexpected devices here (for example, webcams), as well as virtual devices (software pretending to be a microphone). Choose the entry that matches the microphone you actually want to use.
You can also use the Audio Setup toolbar to select whether you'll be recording in Mono or Stereo.
Note: Most microphones are in Mono, and Mono is generally the best choice for recordings. Only use Stereo if you do need directionality.
Turn on the monitoring (shown below) and tap onto your mic. If you see the green bar move when tapping the mic, you have selected the correct device in the previous step.
Then try to speak in a normal volume. In general, the volume should remain in the green zone throughout (in general, between -18 and -12 dB is best).
Caution: If your input volume is too low (below -42 dB) or too high (frequently in the red area), your audio quality will likely suffer. See this page for how to fix this:Setting recording and playback levels
Next, make a test recording. To start recording your voice in Audacity, simply press the red record button.
When you have made the recording, listen back to it. If everything went well, you should now hear your voice clearly and you should now be able to continue with the next steps.
If you run into trouble with any of these steps, you may find the solution here:
Once you've made your recording, make sure to save your work. This applies regardless of whether you intend on editing it later or not. Saving and exporting projects
If you want to edit your recording afterwards: Editing audio
Each effect in Audacity comes with a predefined set of values that you can change and save according to suit your needs and workflow.
When you select an effect to apply to your audio (for example Effect > Noise Removal & Repair > Noise Gate...) Audacity will show you the effect settings window where you can change the different values according to your needs.
After you find the settings that best suit your needs you can use the Presets & settings button to save your settings for future use:
Click the Presets & settings button and select Save preset...
After saving your presets you can recall them the next time you need to apply the same effect. Click the Presets & settings button, select User Presets... and select the name of the previously save presets:
To restore the factory default settings select Presets & settings > Factory Presets > Defaults
This page lists all commands in the Audacity menus and all pre-defined keyboard shortcuts.
The default Standard set of shortcuts is a reduced set, compared to earlier versions of Audacity, to simplify the set of shortcuts somewhat and to provide greater flexibility for users who wish to create their own shortcuts. There is also an extended Full set of keyboard shortcuts that can be selected from the Defaults button on the Keyboard Preferences dialog. This Full set is the set that was available in Audacity 2.1.3 and earlier. You can use Keyboard Preferences to change or remove existing shortcuts or to assign a shortcut to commands that lack a default shortcut.
Standard shortcuts are shown like so: Ctrl + A
.
Shortcuts that are only in the Full set are shown like so: Ctrl + #
Extra.
Shortcuts that have not been assigned, that you can assign using keyboard preferences, are shown like so (unassigned).
Some less commonly used commands are not in the default menus but they can be accessed by menu by enabling Show extra menus in Interface Preferences
Note: You can change all shortcuts via Preferences > Keyboard. This includes adding new shortcuts, or removing shortcuts existing by default.
Other Tips and hints:
Mac users: Ctrl = ⌘ and Alt = Option. So, for example, Ctrl + Alt + K = ⌘ + Option + K.
See Audacity Selection for examples of changing track focus and selection.
PAGE UP scrolls the project rightwards and PAGE DOWN scrolls the project leftwards, equivalent to a single click in the white area either side of the horizontal scrollbar. These shortcuts cannot be configured in Keyboard Preferences.
There are a number of key combinations that can be used in combination with mouse clicks. These cannot be configured. They are listed on Mouse Preferences
The File Menu provides commands for creating, opening and saving Audacity projects and importing and exporting audio files
Action | Shortcut | Description |
---|---|---|
Lists the full path to the twelve most recently saved or opened projects or most recently imported audio files
Various ways to save a project.
For exporting audio files
For importing audio files or label files into your project
The Edit Menu provides standard edit commands (Undo, Redo, Cut, Copy, Paste and Delete) plus many other commands specific to editing audio or labels
For more "advanced" removal of audio
Create or remove separate clips in the audio track. A clip inside an audio track is a separate section of that track which has been split so that it can be manipulated somewhat independently of the other clips in the track.
These commands are to add and edit labels.
Labeled Audio commands apply standard Edit Menu commands to the audio of one or more regions that are labeled. The labels themselves are not affected.
Select Menu has commands that enable you make selections of tracks or parts of the tracks in your project.
Tracks
For modifying, saving and restoring a selection.
For making a selection of a frequency range.
For modifying a selection, taking account of clips.
View Menu has commands that determine the amount of detail you see in all the tracks in the project window. It also lets you show or hide Toolbars and some additional windows such as Undo History.
Zoom in/out on the horizontal axis. Show more detail or show a longer length of time.
Controls the sizes of tracks.
Move forward/backwards through the audio
Toolbars can be used to determine which of the Audacity toolbars are displayed. By default all toolbars are shown except Spectral Selection and Scrub
Transport Menu commands let you play or stop, loop play, scrub play or record (including timed and sound activated recordings).
These commands control playback in Audacity. You can Start, Stop or Pause playback of the audio in your project.
These commands control recording in Audacity. You can Start, Stop or Pause recording in your project. You can either start a recording on your existing track or an a new track.
Scrubbing is the action of moving the mouse pointer right or left so as to adjust the position, speed or direction of playback, listening to the audio at the same time - a convenient way to quickly navigate the waveform to find a particular event of interest. Speed changes are made by rotating the mouse wheel while scrubbing.
These commands let you move the cursor to the start or end of the selection, track or any adjacent Clip that you may have
This submenu lets you manage and set various options for transport (playing and recording) in Audacity
Tracks Menu provides commands for creating and removing tracks, applying operations to selected tracks such as mixing, resampling or converting from stereo to mono, and lets you add or edit labels.
Adds a new track
Mixes down selected tracks to mono or stereo tracks

FFmpeg allows you import/export additional audio file formats into/from Audacity
Due to patent restrictions, FFmpeg cannot be distributed with Audacity itself. However, FFmpeg is required to import and export a variety of audio formats, including M4A and WMA.
Note: In previous versions of Audacity, LAME was required to export MP3 files. It is now included with Audacity by default on Windows and macOS. Make sure you are using the latest version of Audacity if you're getting any LAME errors.
You can download and install FFmpeg as follows:
Download the FFmpeg installer from For most computers, the 64-bit Windows version is correct.
Run the installer. You can ignore the "unknown publisher" warning.
Read and accept the license
Select the location to install FFmpeg. By default FFmpeg will be installed into C:\Program Files\FFmpeg for Audacity
Finish the installation
Restart Audacity
Audacity should now automatically detect FFmpeg and allow you to use it.
If you prefer a manual installation of FFmpeg you can download a ZIP file from a different source:
Or by compiling it from source as described here:
Note:
Audacity 3.1 and later supports avformat-55.dll, avformat-57.dll and avformat-58.dll. Audacity 3.2 and later also supports avformat-59.dll. Audacity 3.3 and later also supports avformat-60.dll. You can check which dll is in which FFmpeg release .
Make sure you download full FFmpeg copies, not just the avformat-*.dll's individually. Further, make sure to download or build the shared versions as only those contain .dll's.
Different versions of FFmpeg may have different codecs enabled in them. In particular, AMR (narrowband) is not featured in the recommended installer.
If you have installed FFmpeg from a different source, or installed it in a different location, you'll need to tell Audacity where to find it. To do this:
Go to Edit > Preferences > Libraries
Click on the Locate... button.
If the following message appears, Audacity has automatically identified FFmpeg:
You can click No as Audacity already knows where to find FFmpeg.
If this message does not appear, proceed with the next steps.
In this dialog window, click Browse... to locate the avformat-*.dll from the FFmpeg folder you downloaded/installed elsewhere
Once you've found it, click Open, then OK, then OK again to close the preferences.
This is a universal binary installer. It automatically matches your system architecture.
When you have finished downloading, open the .pkg. You will be guided through the installation
Click through the steps in the installer.
On some Macs the process may look as though it has stalled on "Validating packages" - just be patient and wait for it to complete.
Restart Audacity if it was running when you installed FFmpeg then Audacity should detect FFmpeg automatically.
If you have problems with Audacity detecting FFmpeg, follow the steps below to manually locate FFmpeg.
And once you have Homebrew, the following command installs FFmpeg:
Audacity should now automatically detect the installation after a restart. If not, follow the steps of a manual installation.
Note:
Audacity 3.1 and later supports avformat 55, 57 and 58. Audacity 3.2 and later also supports avformat 59. Audacity 3.3 and later also supports avformat 60.
Make sure to download or build the shared versions (with .dylib's) as only those can be used by Audacity.
Different versions of FFmpeg may have different codecs enabled in them. In particular, AMR (narrowband) is not featured in the recommended installer.
If you have installed FFmpeg from a different source, or installed it in a different location, you'll need to tell Audacity where to find it. To do this:
Go to Audacity > Preferences > Libraries
Click on the Locate... button.
If a "Success" message appears, Audacity has successfully found FFmpeg. You can click No as Audacity already knows where to find FFmpeg.
If this message does not appear, proceed with the next steps.
In the "Locate FFMPEG" dialog, click Browse... to locate the avformat-*.dylib from the FFmpeg folder you downloaded/installed elsewhere.
Once you've found it, click Open, then OK and OK again to close the preferences.
If you're using an Apple Silicon ("M1", "M2") system, make sure that your FFmpeg and Audacity architectures match:
arm64 (Apple Silicon) Audacity needs arm64 FFmpeg,
x86_64 (intel, also known as x64 and amd64) Audacity needs x86_64 FFmpeg.
Additionally, make sure you're using the latest version of Audacity.
On Linux, you generally can install FFmpeg as well as LAME through the package manager. You can use the following command in your Terminal/Console to install it:
Once you have installed FFMPEG and LAME, restart Audacity. It will automatically try to detect them.
If your FFmpeg or LAME installation didn't get detected, you'll need to tell Audacity where to find it. To do this:
Go to Edit > Preferences > Libraries
Click on the Locate... button of the relevant library.
If a "Success" message appears, Audacity has successfully found the library. You can click No as Audacity already knows where to find the library.
If this message does not appear, proceed with the next steps.
In case of FFMPEG: In the "Locate FFmpeg" dialog, click Browse... to locate the libavformat.so.* from the FFMPEG folder you downloaded/installed elsewhere. In case of LAME: In the "Locate LAME" dialog, click Browse... to locate the libmp3lame.so that you downloaded/installed elsewhere.
Once you've found it, click Open, then OK and OK again to close the preferences.
Audacity can record computer audio (including sound from YouTube, Spotify and more).
Click on Audio Setup and select Windows WASAPI as the Host
Select the output you want to use (the device you're using to listen) as the input. It will be marked with a (loopback) after it's name.
When using the (default) MME device, you may find a virtual microphone called Stereo Mix, What you hear or similar in it. This also will record your desktop audio.
Note: MacOS does not have built-in desktop audio recording capabilities. You'll need to download Soundflower to record desktop audio.
Caution: Soundflower is not compatible with Apple Silicon-based machines ("M1", "M2", ...)
Open the Audio MIDI Setup app (found in /Applications/Utilities
).
Press the + button in the bottom left corner and select "Create Multi-Output Device".
In the panel that appears to the right, select Built-in Output and Soundflower (2ch).
Press the gear button in the bottom left and select "use this device for sound output". Note: If you don't set an option, you won't hear anything after completing the following steps.
Start Audacity
Click the Audio Setup button and set Soundflower (2ch) as the recording device.
When using PulseAudio (default for Ubuntu, Linux Mint, and others):
Install PulseAudio Volume Control (pavucontrol). This should be in your repository already.
Use the Audio Setup toolbar to select ALSA as the audio host and select pulse as the recording device.
If your system uses Pulse by default, the pulse device may be called default.
Enable the recording meter by selecting Start Monitoring.
Open PulseAudio Volume Control and choose the Recording tab.
In the Capture from dropdown, select the "Monitor" option of the playback device used by the application you want to record from
Launch the application that you wish to record and begin playback.
In the "Recording" tab of PulseAudio Volume Control, drag the volume sliders so that the recording level in Audacity's Recording Meter is to left of 0 dB (-6 dB is a good level to aim for).
Recording the desktop audio will record all desktop audio, including notification-pings, games, and Audacity itself (for example, other tracks in the timeline if you're using overdub). So unless you specifically want these noises, make sure to turn them off.
Hit the record button to record your desktop audio.
Audacity comes with 4 themes preinstalled: Light, Dark, Classic and High Contrast. You can switch between themes by going to Edit -> Preferences -> Interface (macOS: Audacity -> Preferences -> Interface)
Once you have chosen a theme, click OK to close the preferences dialog and load the new theme.
Custom themes commonly are distributed as files called ImageCache.png. You can find some custom themes here:
To install a custom theme, place the ImageCache.png in the following folders. You may create the folders if they aren't present.
Windows: C:\Users\<username>\AppData\Roaming\Audacity\Theme\custom\
MacOS: ~/Library/Application Support/audacity/Theme/custom/
Linux: ~/.local/share/audacity/Theme/custom/
Then,
restart Audacity,
open the Preferences -> Interface page,
select Custom as the theme and
press OK.
Be aware that custom themes may break from one Audacity version to the next.
Audacity 3.2 and onwards supports realtime effects
While Audacity doesn't yet ship with realtime effects, you can download plugins for it. Currently supported plugin formats are Audio Units (macOS only), VST3, VST, LV2, and LADSPA. We have collected some plugins which we know to work on but you can find many more across the web. Once you install the plugins, they should be detected by Audacity once you restart it, if not, see the .
You can add realtime effects using the following steps:
Note: Realtime effects always apply to an entire track. Since they're calculated realtime, they won't change the source waveform.
You can change the effect settings by clicking on the effect's name. This will open a settings window, often with a graphical interface which looks nothing like Audacity itself. You still can interact with the main Audacity window while the effect settings are open.
You can press the blue power button next to an effect (or the entire effects stack) to bypass it, causing it to be not applied to your audio.
Tip: If you want to completely remove an effect from the stack, press the triangle next to the effect name and select "No Effect".
That said, you can apply the effect stack to the waveform by first selecting the track and then going to Tracks > Mix > Mix and Render.
Caution: When selecting several tracks at once, the Mix and Render option will mix all tracks together.
Select the bad part of the recording and silence it. You can do this by clicking the Silence Audio Selection button (found next to the undo and cut/copy/paste buttons), or by pressing Ctrl+L
(Cmd+L

Shows the list of available LADSPA effects but only if the user has effects "Grouped by Type" in Effects Preferences.
Nyquist
(unassigned)
no tip string.
Amplify...
(unassigned)
Increases or decreases the volume of the audio you have selected.
Auto Duck...
(unassigned)
Reduces (ducks) the volume of one or more tracks whenever the volume of a specified "control" track reaches a particular level. Typically used to make a music track softer whenever speech in a commentary track is heard.
Bass and Treble...
(unassigned)
Increases or decreases the lower frequencies and higher frequencies of your audio independently; behaves just like the bass and treble controls on a stereo system.
Change Pitch...
(unassigned)
Change the pitch of a selection without changing its tempo.
Change Speed...
(unassigned)
Change the speed of a selection, also changing its pitch.
Change Tempo...
(unassigned)

Click Removal...
(unassigned)
Click Removal is designed to remove clicks on audio tracks and is especially suited to declicking recordings made from vinyl records.
Compressor...
(unassigned)
Compresses the dynamic range by two alternative methods. The default "RMS" method makes the louder parts softer, but leaves the quieter audio alone. The alternative "peaks" method makes the entire audio louder, but amplifies the louder parts less than the quieter parts. Make-up gain can be applied to either method, making the result as loud as possible without clipping, but not changing the dynamic range further.
Distortion...
(unassigned)
Use the Distortion effect to make the audio sound distorted. By distorting the waveform the frequency content is changed, which will often make the sound "crunchy" or "abrasive". Technically this effect is a waveshaper. The result of waveshaping is equivalent to applying non-linear amplification to the audio waveform. Preset shaping functions are provided, each of which produces a different type of distortion.
Echo...
(unassigned)
Repeats the selected audio again and again, normally softer each time and normally not blended into the original sound until some time after it starts. The delay time between each repeat is fixed, with no pause in between each repeat. For a more configurable echo effect with a variable delay time and pitch-changed echoes, see Delay.
Fade In
(unassigned)
Applies a linear fade-in to the selected audio - the rapidity of the fade-in depends entirely on the length of the selection it is applied to. For a more customizable logarithmic fade, use the Envelope Tool on the Tools Toolbar.
Fade Out
(unassigned)
Applies a linear fade-out to the selected audio - the rapidity of the fade-out depends entirely on the length of the selection it is applied to. For a more customizable logarithmic fade, use the Envelope Tool on the Tools Toolbar.
Filter Curve...
(unassigned)
Adjusts the volume levels of particular frequencies
Graphic EQ...
(unassigned)
Adjusts the volume levels of particular frequencies
Invert

This effect flips the audio samples upside-down. This normally does not affect the sound of the audio at all. It is occasionally useful for vocal removal.
Loudness Normalization...
(unassigned)
Changes the perceived loudness of the audio.
Noise Reduction...
(unassigned)
This effect is ideal for reducing constant background noise such as fans, tape noise, or hums. It will not work very well for removing talking or music in the background. More details here.
Normalize...
(unassigned)
Use the Normalize effect to set the maximum amplitude of a track, equalize the amplitudes of the left and right channels of a stereo track and optionally remove any DC offset from the track
Paulstretch...
(unassigned)
Use Paulstretch only for an extreme time-stretch or "stasis" effect, This may be useful for synthesizer pad sounds, identifying performance glitches or just creating interesting aural textures. Use Change Tempo or Sliding Time Scale rather than Paulstretch for tasks like slowing down a song to a "practice" tempo.
Phaser...
(unassigned)
The name "Phaser" comes from "Phase Shifter", because it works by combining phase-shifted signals with the original signal. The movement of the phase-shifted signals is controlled using a Low Frequency Oscillator (LFO).
Repair

Reverse
(unassigned)
Reverses the selected audio; after the effect the end of the audio will be heard first and the beginning last.
Sliding Stretch...
(unassigned)
This effect allows you to make a continuous change to the tempo and/or pitch of a selection by choosing initial and/or final change values.
Truncate Silence...
(unassigned)
Automatically try to find and eliminate audible silences. Do not use this with faded audio.
Wahwah...
(unassigned)
Rapid tone quality variations, like that guitar sound so popular in the 1970's.
Adjustable Fade...
(unassigned)
enables you to control the shape of the fade (non-linear fading) to be applied by adjusting various parameters; allows partial (that is not from or to zero) fades up or down.
Clip Fix...
(unassigned)
Clip Fix attempts to reconstruct clipped regions by interpolating the lost signal.
Crossfade Clips
(unassigned)
Use Crossfade Clips to apply a simple crossfade to a selected pair of clips in a single audio track.
Crossfade Tracks...
(unassigned)
Use Crossfade Tracks to make a smooth transition between two overlapping tracks one above the other. Place the track to be faded out above the track to be faded in then select the overlapping region in both tracks and apply the effect.
Delay...
(unassigned)
A configurable delay effect with variable delay time and pitch shifting of the delays.
High-Pass Filter...
(unassigned)
Passes frequencies above its cutoff frequency and attenuates frequencies below its cutoff frequency.
Limiter...
(unassigned)
Limiter passes signals below a specified input level unaffected or gently reduced, while preventing the peaks of stronger signals from exceeding this threshold. Mastering engineers often use this type of dynamic range compression combined with make-up gain to increase the perceived loudness of an audio recording during the audio mastering process.
Low-Pass Filter...
(unassigned)
Passes frequencies below its cutoff frequency and attenuates frequencies above its cutoff frequency.
Notch Filter...
(unassigned)
Greatly attenuate ("notch out"), a narrow frequency band. This is a good way to remove mains hum or a whistle confined to a specific frequency with minimal damage to the remainder of the audio.
Spectral edit multi tool
(unassigned)
When the selected track is in spectrogram or spectrogram log(f) view, applies a notch filter, high pass filter or low pass filter according to the spectral selection made. This effect can also be used to change the audio quality as an alternative to using Equalization.
Spectral edit parametric EQ...
(unassigned)
When the selected track is in spectrogram or spectrogram log(f) view and the spectral selection has a center frequency and an upper and lower boundary, performs the specified band cut or band boost. This can be used as an alternative to Equalization or may also be useful to repair damaged audio by reducing frequency spikes or boosting other frequencies to mask spikes.
Spectral edit shelves...
(unassigned)
When the selected track is in spectrogram or spectrogram log(f) view, applies either a low- or high-frequency shelving filter or both filters, according to the spectral selection made. This can be used as an alternative to Equalization or may also be useful to repair damaged audio by reducing frequency spikes or boosting other frequencies to mask spikes.
Studio Fade Out
(unassigned)
Applies a more musical fade out to the selected audio, giving a more pleasing sounding result.
Tremolo...
(unassigned)
Modulates the volume of the selection at the depth and rate selected in the dialog. The same as the tremolo effect familiar to guitar and keyboard players.

Modify an envelope by specifying a track or channel and a time within it. You cannot yet delete individual envelope points, but can delete the whole envelope using Delete=1.
Set Label...
(unassigned)
Modifies an existing label. You must give it the label number.
Set Project...
(unassigned)
Sets the project window to a particular location and size. Can also change the caption - but that is cosmetic and may be overwritten again later by Audacity.
Select...
(unassigned)
Selects audio. Start and End are time. First and Last are track numbers. High and Low are for spectral selection. FromEnd allows selection from the end, which is handy to fade in and fade out a track. The Mode parameter allows complex selections, e.g adding or removing tracks from the current selection.
Set Track...
(unassigned)
Sets properties for a track or channel (or both). Setting one channel of a stereo track can lead to interesting results. That's most used when setting relative sizing of the two channels. SpectralPrefs=1 sets the track to use general preferences, SpectralPrefs=1 per track prefs. When using general preferences, SetPreferences can be used to change a preference and so affect display of the track. Name is used to set the name. It is not used in choosing the track.
Get Info...
(unassigned)
Gets information in a list in one of three formats.
Message...
(unassigned)
Used in testing. Sends the Text string back to you.
Help...
(unassigned)
This is an extract from GetInfo Commands, with just one command.
Import...
(unassigned)
Imports from a file. The automation command uses a text box to get the file name rather than a normal file-open dialog.
Export...
(unassigned)
Exports to a named file. This version of export has the full set of export options. However, a current limitation is that the detailed option settings are always stored to and taken from saved preferences. The net effect is that for a given format, the most recently used options for that format will be used.
Open Project...
(unassigned)
Opens a project.
Save Project...
(unassigned)
Saves a project.
Move Mouse...
(unassigned)
Experimental command (called Drag in scripting) that moves the mouse. An Id can be used to move the mouse into a button to get the hover effect. Window names can be used instead. If To is specified, the command does a drag, otherwise just a hover.
Compare Audio...
(unassigned)
Compares selected range on two tracks. Reports on the differences and similarities.
Screenshot (short format)...
(unassigned)
A version of Tools -> Screenshot with a more minimal GUI. One of the most useful options is All_Tracks. The _Plus suffix includes the timeline.
Quick Help...

Macros (formerly known as Chains) let you chain together multiple commands to automate repetitive tasks.
Debian, Ubuntu, Pop_OS!, Mint |

You can adjust volume and panning per track on the left-hand side of any track:
Note: If you collapse a track or make it vertically smaller, Audacity will hide the pan and volume sliders from view. To see them again, expand the track by dragging down on it's lower edge.
You can access the Mixer Board via View > Mixer Board.
This shows all track controls side-by-side, with a volume slider on the left per track, as well as per-track volume meters.
By default, the icon for each track is the Audacity logo, but it can be changed if the track name contains the following keywords:
acoustic piano, acoustic pno = acoustic piano
back vocal, back vox, bg = backing vocal
electric piano, electric pno, key = electronic keyboard
loop = loop track
sax = saxophone
synth = synthesizer
trumpet, horn = generic brass instrument
turntable = record player
vibraphone, vibes = vibraphone
vocal, vox = lead vocal
acoustic guitar, acoustic gtr = acoustic guitar
electric bass, bass, bs = electric bass guitar
electric guitar, guitar, gtr = (standard) electric guitar
string, violin, cello = generic stringed instrument
clap = handclaps
drums, dr = drum kit
kick = kick drum
perc = percussion
snare = snare drum
tambourine, tambo = tambourine
Once you have your changes to mixing, panning and other real-time effects final and want to apply them onto the waveform itself, you can render the mix using Tracks > Mix > Mix and Render. This replaces all selected tracks with the mix. If you have used many tracks and real time effects, this may considerably improve performance.
Caution: When rendering, all tracks are added onto each other, which may cause clipping. If this happens, undo the mix and lower the volume for all of your tracks.
Best Practice: If you have a several stereo tracks, but don't need a stereo-effect for them (ie. any left/right panning), consider mixing down to mono using Tracks > Mix > Mix Stereo Down to Mono. Exporting a mono track to a lossy format (like MP3) will let you have a higher quality at the same bitrate, or let you use a lower bitrate (and thus lower file size) at the same bitrate.
Crossfades blend the end of one song with the beginning of the next one. There are several methods to achieve this in Audacity.
If you have two clips in one track you'd like to crossfade, you can use Crossfade Clips effect. To use it:
Have two clips in one track.
Select the region you'd like to apply the crossfade to. Try to select roughly the same amount of time in both clips.
Note: Any empty space between the clips will be automatically removed and ignored in the crossfade.
Use Effects > Fading > Crossfade Clips to crossfade the clips.
To crossfade between tracks, use the following steps:
Position the clips on the tracks so that they overlap in the range you want to crossfade, and select the audio in the overlapping region in both clips:
Use Effects > Fading > Crossfade Tracks to crossfade the tracks.
Apply this normalization effect to set the target loudness required by podcast platforms, television/radio programmes and some websites
Audacity provides you with two different built-in normalization effects available through the Effect -> Volume and Compression menu:
Loudness Normalization
Normalize
Normalize is a peak normalization effect which apply gain or reduction to the selected audio so the level of the peak is changed to the desired level. You set the desired level of the peak (in dBFS) before applying the effect. This effect does not take into account the perceived loudness of the selected audio only the desired peak level.
By comparison Loudness Normalization will calculate the perceived loudness of the selected audio and then apply gain or reduction to the audio so a desired loudness level is reached. You set the desired loudness (in LUFS, Loudness Units relative to Full Scale).
To apply Loudness Normalization:
Select the region containing the audio that you want to normalize. It could be an audio clip or the entire track.
Click Effect -> Volume and compression -> Loudness Normalization... to open the Loudness Normalization window
Set the target loudness in LUFS units using the Normalize perceived loudness to field.
Keep Normalize stereo channels independently disabled If you are normalizing a stereo track (Left and Right channels) with the audio levels already balanced as this mode will preserve its original stereo balance.
Disable Treat mono as dual-mono (recommended) if you are normalizing a mono track.
Best practice: Adjusting the audio's amplitude with this effect is normally best performed as a final editing step prior to export of the production audio.
Manage Macros allows you to edit, remove or rename existing Macros or add a new Macro. It also allows you to apply Macros to you project or a set of files.
Any , , , , or (Mac) effect shown in the can be added to a Macro. You can also add plugins in any format that are shown in the or Menus (including analysis effects), the built-in analyzer and a number of export commands.
Macros may be applied to either the entirety of the current project or to a selection of files using the Tools > command.
It is possible to use in Macros but see for how the Noise Profile is captured.
The full list of all Macro commands, with descriptions, is available at Scripting Reference.
You can access the Manage Macros dialog by using either:
The menu > Manage Macros, or
The Expand button in the dialog.
Select Macro contains a list of already defined Macros. You can define the name of a new Macro and select which Macro is active.
The left hand box in the dialog (labeled Select Macro) contains a list of already defined Macros. Until you add a new Macro, it only has built-in MP3 Conversion and Fade Ends Macros.
Use left-click (or use the Up or Down keyboard arrows) to select the Macro you want to work on
New: Adds a new Macro to the list.
Remove: Remove the selected Macro from the list - grayed out when the Macros that ship as part of Audacity are selected.
Rename...: Rename the selected Macro - grayed out when the Macros that ship as part of Audacity are selected.
Restore: Resets any Audacity provided Macro to its default settings - grayed out when user-provided Macros are selected.
Import...: Enables you to import a Macro from a TXT file.
Export: Exports the selected Macro to a TXT file.
The Macro can include a number of common Audacity functions and effects to be executed in any order you specify.
The Export command will use the settings you used the last time you used the same command from the File > Export > Export... menu command, or default settings if you have never used that command from the menu.
In many cases the parameters for each command in the Macro can be specified within the Manage Macros dialog.
You can:
Add or remove commands for the selected Macro
Change the order in which the commands execute in the Macro
Edit the parameters for some effects in the Macro
Insert: Insert a new command into the list
Edit...: Edit the parameters of the currently selected command
Delete: Delete the currently selected command in the list
Move Up: Move the currently selected command up in the list
Move Down: Move the currently selected command down in the list
Save: This button is only active when you have made edits to a Macro. It enables you to save those changes.
You can also edit an existing command by double-clicking it, or using the Up or Down keyboard arrow to select it and then pressing Space. The parameter settings dialog for that command will be displayed.
A few commands are intentionally omitted from the Macro Manager (such as Close:) because they are unsuitable for use in Macros.
To insert a new command in a Macro, left-click or use the Up or Down keyboard arrow to select an existing command and then press Insert. The new command will be placed above this selected command.
The Select Command dialog appears, listing all the available commands. Double-click a command from the list to insert it in the "Command" box, as shown in the image below after inserting "Normalize".
Alternatively, use the Up or Down keyboard arrow to select the command, then press Space.
Some scriptable commands are particularly useful for Macros. See these pages for details:
If the command has editable parameters, the Edit Parameters button will be active. Clicking this button will bring up the dialog box for the effect where you can set the parameters as if you were applying the standalone effect.
Choose OK in the effect dialog to accept the parameters you entered, or Cancel to revert to the default parameters.
Choose OK in the Select Command dialog to add the command to the Macro.
It is strongly recommended that you set parameters for the commands that you use in a Macro. Otherwise Audacity will use the last-used parameter setting(s) when you ran the effect(s) manually.
Also note carefully that settings used in Macros will not affect or change the last-used parameter settings for any effect when next run manually.
This example shows the Set Track Status command.
The tick boxes on the left determines whether a feature should be used. When not selected, that feature does nothing.
The second tick box determines whether the feature is set to "on" or "off".
This shows:
The track name will not be changed
Track selectedness will be set to Not Selected
Track focus will be set to Focused
Commands that call Effects, Generators, Analyzers or Tools, use the same familiar graphical interface (GUI) as appears when they are used from the normal top level menus.
Macros will work on pre-existing selections you make in your project prior to running the Macro. But the selection can be over-ridden by your Macro itself as there are Macro commands available to effect selections in the audio.
In particular All(Select All) will select the entire project
Select which is parameterizable (see the provided Fade Ends Macro for an example where the first and last one seconds of the audio are selected for the fades).
If you want to select all tracks, maintaining your current time selection, use "Select: First=0 Last=100". It will not waste time twiddling its thumbs on the tracks that are not there.
When applying a Macro to files there is no pre-existing selection so you will need to create a selection in the Macro if your Macro requires audio to be selected to act on (and most Macros do).
There are four basic export commands available: Export as WAV, Export as MP3, Export as FLAC and Export as Ogg.
Parameters for export formats cannot be set in Manage Macros. To configure export parameters for the Macro, click File > Export > Export Audio... to access the Export Audio Dialog, click Options, set the parameters, press OK then Cancel the export. An audio track must be on screen in order to open the Export Audio Dialog.
Note carefully that the filename is not dynamically changeable when running the Macro, once set in the Export2 parameters, so you may wish to create several Macros the Export2 each targeting different file locations, names and filetype.
Example:
"C:\Users\<username>\Desktop\my file.flac" (this works)
Not: C:\Users\<username>\Desktop\my file.flac (the file name is not quoted)
Not: "my file.flac" (no path given)
Not: "C:\Users\<username>\Desktop\myfile" (no file extension)
The quote marks around the file pathing are supplied by Audacity once the Export2 command has been edited in setting up or editing the Macro
When entering the pathing data in the edit parameters dialog for the command you do not put the quote marks for example: C:\Users\<username>\Desktop\my file.flac
The following two commands are now deprecated and may well be removed in future versions of Audacity. They were part of "CleanSpeech" (which has long been removed from Audacity).
The name of the MP3 exported by the "Export as MP3 56k before" command is prefixed by "MasterBefore_" followed by the date and time. The name of the MP3 exported by the "Export as MP3 56k after" command is prefixed by "MasterAfter_" followed by the date and time.
Comments be added to Macros to enable you to document what is happening in the Macro.
Add a comment to your macro using the Comment command and edit its parameters to type the text of your comment.
Use the Shrink button to show a reduced Macros Palette dialog with a simple list of the existing Macros, enabling you to apply the Macros but not edit them.
This smaller version is useful for presets. It stays open after applying a macro, so it is a palette of custom functions, and you can pick another and apply that.
Apply Macro to enables you to make a Macro operate on either your current open Project or a set of selected external Files.
It is recommended not to process more than 500 files at a time
To dismiss the dialog simply click on the Close button.
If there any unsaved changes you will be asked if you want to save them or not.
This error may sometimes occur for one or more commands in a Macro when updating from a previous Audacity version. The error may also occur if users sharing Macro have different Audacity versions or different versions of the plugins used in the Macro. The error will occur if:
any command in the Macro uses a different text format than that recognized by the version of Audacity in use
any plugins listed in the Macro are missing, in an incorrect location or are incompatible with the version of Audacity in use.
This is a suite of Audacity tools and process to help you produce an audiobook reading that reaches ACX Technical Compliance.
See at the end for general information about this process
Download and install the plugin which will help you check the levels of your recording.
Check for instructions on how to install the ACX Check plugin
If you are using a version of Audacity previous to 2.4.1 you will also need to download and install
Start this process with an unedited recording. No processing, adjustments or fixes.
Export a WAV (Microsoft) 16-bit sound file of your raw reading and save it in a safe place—ideally not on the machine. You should never be stuck reading a chapter again because of an accident. Saving an Audacity Project is not recommended for this.
To automate the audiobook mastering process, first download the macro:
Then, in Audacity, go to Tools -> Macro Manager and press the Import... button and browse to the file. Import it and then close the Macro Manager.
You now can apply the Audiobook Mastering Macro via Tools -> Apply Macro -> Audiobook-Mastering-Macro similarly to how you would apply any individual effect.
These instructions are in short-form: Menu > Tool : Options > Apply
Select the whole reading or chapter by clicking the Select button at the bottom of the Track Control Panel.
Effect > EQ and Filters > Filter Curve EQ... : Presets & settings > Factory Presets > Low roll-off for speech > Apply.
Effect > Volume and Compression > Loudness Normalization... : Normalize RMS to -20dB > Apply.
Effect > Volume and Compression > Limiter... : Soft Limit, 0.00, 0.00, -3.50dB, 10.00, No > Apply.
Analyze > ACX Check.
The first two readings, Peak (no louder than -3dB) and RMS (between -18dB and -23dB) should be nearly perfect. If the noise is quieter than about -65dB (-60dB limit), and the show sounds reasonable, you may be done.
The tool settings are sticky and you don't have to keep typing them in. If you do no other editing, mastering a chapter comes down to:
Select the audio track or clip.
Effect > EQ and Filters > Filter Curve... > Apply.
Effect > Volume and Compression > Loudness Normalization... > Apply.
Effect > Volume and Compression > Limiter... > Apply.
This mastering suite addresses technical considerations. Nothing here will address theatrical errors such as harsh sibilance, gritty voice or wet mouth noises. There is no acting filter. You have to know how to read aloud.
The quality of the original recording is very important. It's easy to record mistakes that can't be fixed later. Record to a reasonable volume (occasional peaks at -6dB) in a quiet room with no echoes.
When you get done with a chapter, File > Export the work as WAV (Microsoft, 16-bit) and save the sound file with a unique name somewhere safe. That's your emergency backup so you don't have to read it again if you damage the work or lose your edit.
Only then start editing, processing, filtering and correcting. Keep testing the work with the ACX Check plugin as you go. Select the work and Analyze > ACX Check.
Peaks no louder than -3dB.
RMS (performance loudness) between -18dB and -23dB.
Noise no louder than -60dB.
Those are the three values displayed in the ACX Check panel
Human Quality Control at ACX (the theatrical test after you pass ACX-Check technical test) does not like heavy processing. You should be as gentle as you can with as few corrections as possible. Don't even think of submitting readings that sound like a bad cellphone, speaking into a wineglass or reading in a bathroom.
The Audiobook metaphor is listening to someone telling you a story over cups of tea. Anything that distracts from that ideal should be avoided.
We assume you've already been through Audiobook Mastering and failed ACX Technical Compliance because of noise (louder than -60dB) or your performance has odd background sounds you don't like. Noise is common in a home studio.
This is a gentle spring rain in the trees sound behind your voice. Microphone systems make noises like this naturally and it's your job to make your voice loud enough so nobody notices the noise, but not so loud your voice distorts.
If the hiss isn't too bad, try a gentle correction such as Noise Reduction of the Beast (6, 6, 6) or Edit > Undo and try 9, 6, 6. You can hear the hiss getting quieter and recede into the background as you increase the first number. Apply Nose Reduction and then try ACX Check again. If you need reduction as high as 12, 6, 6, your voice may get wine-glassy or honky and the show may not pass ACX inspection.
The solution may be to change your announcing style or even the microphone. You should be about a shaka away from the microphone...
... or as close as a fist (louder and more intimate) but you may need a pop and blast filter.
Computer fan, air conditioning, refrigerators or other machines.
If possible turn off fans or machines while you're presenting. And yes, we understand the contradiction of needing to watch the Audacity screen, remove the noisy computer from your room and keep the computer one USB cable away from your USB microphone all at the same time.
People have done it by extending the keyboard, mouse and monitor outside their studio, but you are warned against extending a USB cable, particularly with audio (or video) production.
Do not block computer vent holes.
If machine noises are constant and not seriously loud, they may respond to Effect > Noise Removal and Repair > Noise Reduction...
Try a gentle correction such as Noise Reduction of the Beast (6, 6, 6) or UNDO and try 9, 6, 6. You can hear the hiss getting quieter and recede into the background as you increase the first number: Nose Reduction. Try ACX-Check. If you need reduction as high as 12, 6, 6, your voice may get wine-glassy or honky and the show may not pass ACX inspection.
Some computers and USB microphones hate each other and produce mosquito whine sound.
Whine doesn't respond well to Effect > Noise Removal and Repair > Noise Reduction.
Effect > n / a > Mosquito-Killer4: ...Mosquitoes to kill?: 8 > Apply.
I don't know of any easy, foolproof way to permanently fix a USB microphone once you have the whine sound. The most likely fix is change the computer. ACX did it by not using a USB microphone. They used a very high quality analog microphone plugged into a stable USB interface.
There are no tools to remove noises that constantly change. If jets overhead, traffic noises, dogs barking and the TV next door are included in your show, they are now your permanent performance partners. Read the work again in a quieter room. Gating doesn't help.
You can apply any of the existing macros using the Macros Palette. To open it you can either:
Use the menu Tools > Apply Macros > , or
Use the Shrink button in the dialog
Once invoked, the Macros Palette window will remain on-screen, actively available, at all times unless and until you dismiss it or close Audacity.
In the "Macro" list, left-click on a Macro (or use Up or Down keyboard arrow) to select the Macro you want to apply.
Use the Project button to apply the selected Macro to the current project.
The typical purpose of this option is effect automation - apply a sequence of effects to the project, using effect parameters and an order of applying the effects that you have found to work well for the type of audio you are processing. This saves time and provides consistency in your workflow.
Macros will work on pre-existing selections you make in your project prior to running the Macro. But the selection can be over-ridden by your Macro itself as there are macro commands available to effect selections in the audio. In particular All(Select All) will select the entire project and Select which is parameterizable (see the provided Fade Ends Macro for an example where the first and last one seconds of the audio are selected for the fades).
Use the Files... button to apply the selected Macro to selected external audio files that are in a single directory.
You cannot apply a Macro to multiple Audacity AUP3 project files, instead you need to use Python scripting.
The selected Macro must include an Export step, otherwise the processed audio will not be retained.
A standard File Open dialog box will appear. Choose a directory then you can select one or any number of supported audio files in that directory, including older AUP project files (but not AUP3 project files).
You cannot select files outside that directory, and files in folders inside that directory will not be processed.
It is convenient therefore to first put all the audio files you want to process into one folder before applying the Macro.
After selecting the audio files you want to process, choose Open.
Each file will be imported into Audacity and processed, exported to the format you chose in the Macro, then the processed audio will be removed so as to clear the temporary disk space that had been used.
If you leave the entry for Macro output blank in Directories Preferences then Audacity will default to creating a folder called "macro-output" in:
Windows: C:\Users\<your username>\Documents\Audacity
Mac: /Users/<your username>/Documents
Linux: /home/<your username>/Documents
It is recommended not to process more than 500 files at a time.
To dismiss the dialog simply click on the Cancel button
Otherwise the dialog will remain open on the screen, but allowing you to perform other Audacity functions.
Notes:
As of Audacity 3.3, these features are still in beta.
A measure and a bar are the same thing. Audacity uses "bar" in places where "measure" would be too long.
You can enable a more musical view in Audacity as follows:
Right-click the Timeline Ruler and select Beats and Measures.
Go to View -> Toolbars and enable Time Signature Toolbar (beta).
In the Time widget, select beats or for more subdivisions, beats and 16th.
Enable Snapping, and set the snapping interval to a musical option (eg 1/4, 1/8 or 1/16).
Once you have enabled all of them, your Audacity may look something like this:
It is important to enter a tempo that matches your content, otherwise none of the features outlined above work properly.
If you're recording music on your own, try playing to a metronome to ensure you stay in tempo.
If you're using music downloaded from the web, try figuring out its tempo. In some cases, a web search for song title
tempo
is sufficient.
IBT - INESC Beat Tracker
Simple Fixed Tempo Estimator form the Vamp SDK example library
Tempo and Beat Tracker: Tempo from the Queen Mary University of London
Audacity is not yet able to handle midway tempo changes during a song.
Audacity will snap the beginning of the clip to the beats and measures grid, depending on your tempo and snapping setting. If your first beat doesn't start exactly at the start of the clip, you can trim the beginning of the clip. To trim a clip, simply drag the upper edge of it inwards.
When trimming a clip, you may need to turn off snapping to make finer adjustments.
Once you have everything set up and snapping enabled, simply dragging your clips will align them to the beat and measures grid.
This page provides some examples of how the Macros feature in Audacity can be used.
A batch processing Macro to compress and normalize files then convert them to MP3:
Insert to reduce the of each WAV, also normalizing them to maximum of 0
Insert Export as MP3 to convert them to format
Click Apply Macro to: Files... to select the files on which to run the Macro.
Click OK to close the Manage Macros window
Alternatively you can choose Tools > Apply Macro..., select the Loud MP3 Macro then click Apply Macro to: Files... where you can select the files on which to run the Macro
An effects automation Macro for the current project that applies noise reduction and equalization:
Insert another Normalize at different settings (without offset removal, setting a final amplitude of -1 dB)
If a Noise Profile exists, that Noise Profile will be used. It is often best to capture a suitable Noise Profile before running a Macro.
If a Noise Profile does not exist:
If the Macro is applied to the current project (as above), the current selection is used to create the Noise Profile. Therefore, other effect commands in the Macro will also only apply to that selection. If an export command is added, the entire file will be exported.
If the Macro is applied to files, the first file (all of it) is used to create the Noise Profile. It may be useful to prepare a file containing a suitable Noise Profile and name it so that it is alphabetically the first file of those to be run in the Macro.
The Select command with 'Relative To=Selection' can be used to extend and contract a selection.
Command: "Select: RelativeTo=Selection Start=-1 End=1" Description: This command expands a selection by two seconds
Command: "Select: RelativeTo=Selection Start=1 End=-1" Description: This command contracts a selection by two seconds
Command: "Select: RelativeTo=Selection Start=1 End=1" Description: This command moves a selection right by one second
Command: "SelTrackStartToEnd" Description: This command (from Select > Region > Track Start to End) Selects all audio in all selected tracks.
Command: "SelNextClip" and "SelPrevClip" Description: These commands are useful with Clips
This Macro takes a single mono track, and converts it to a stereo track, with one channel a spectrogram and the other a wave.
It is one example of how to creatively abuse the Macro system, since audacity is not set up to handle mixed views on wave tracks.
Note the use of a TrackCount of 0.5 to select just one of two channels in a stereo track.
The TrackCount of 0 is used to unselect all tracks.
With normal project rate of 44100Hz, this selects about 126 samples centered on the cursor, and applies the 'Repair' effect to it. 'Repair' can only handle up to 128 samples.
Audacity has several powerful spectral analysis tools: Spectrogram View per track, Plot Spectrum, as well as support for Plugins.
Each track in Audacity can be viewed in a Spectrogram view:
To access it, click on the track menu dropdown and select Spectrogram.
The track menu also features Spectrogram settings, where you can tweak the scale, the colors, the used algorithms and the window size.
Tip: To view the waveform and the spectrogram at the same time, choose Multi-view instead.
You may notice that the spectrogram is somewhat blurry usually, where even if you have a precise frequency, the spectrogram makes it look like a whole range of frequencies is being played. This is an inherent mathematical tradeoff related to the window size:
Depending on what you're after, you can change the window size to fit your analysis: Smaller window sizes benefit time resolution, larger window sizes benefit frequency resolution.
Tip: If you change the algorithm from Frequencies to Reassignment, Audacity will attempt to sharpen both time and frequency resolution using the method of reassignment. This works best for signals that are separable in time and frequency with respect to the analysis window.
You can change both the window size and the algorithm in the spectrogram settings found in the Track Menu dropdown.
You can zoom vertically in Spectrogram View by right-clicking the frequency scale.
Additionally, while hovering over the frequency scale, you can
Ctrl+Scroll to zoom in/out on the frequency scale and
Shift+Scroll to scroll up/down while staying on the same zoom level.
To use Plot Spectrum,
select the audio you're interested in analyzing
go to Analyze -> Plot Spectrum.
Spectrum (default) Plots the fast Fourier Transform (FFT) of the data, with the FFT window size being determined by the Size dropdown. The amplitudes are normalized such that a 0 dB sine (pure tone) will be (approximately) 0 dB on the graph.
Autocorrelation These options measure to what extent the sound repeats itself. This is done by taking two copies of the audio, and moving one forward by one sample. The two copies are then multiplied together, and all the values added up. This is repeated for two samples difference and so on, up to the number of samples in the size option. This gives a small result if the waveform is random (for example, noise) and a large result if it is repetitive (like a musical note). By looking at the peaks in the plot, the key frequencies present can be determined even if there is a lot of noise.
Cepstrum The cepstrum of an audio signal is related to the spectrum, but presents the rate of change in the different spectrum bands. It's particularly useful for properties of vocal tracks and is used, for example, in software to identify speakers by their voice characteristics.
Function offers choices like Rectangular, Hann, Hamming and others. We suggest you use the default Hann for most situations.
Click the Export... button to export the current view as a tab-separated value text file.
This page describes some methods to try to isolate vocals in stereo tracks.
Note: There is no reliable way of separating vocals. The methods described in the article depend on the position of the vocal track in the stereo field.
If the vocals are panned in the center of a stereo track this method can sometimes be effective by removing what is common to both tracks (that is, the vocals), leaving behind what is different (that is, the instrumentals).
Audacity includes the Vocal Reduction and Isolation effect which provides the Remove Vocals option that you can use to try to remove vocals from a stereo track.
Vocal Reduction and Isolation also lets you specify the audio frequency range for vocals (by default 120 to 9000 Hz). This can help cure the common problem where center-panned bass or Hi-hat is also removed when removing vocals.
Note that the end result may not be total vocal isolation or even satisfactory isolation of the vocals; it all depends on how the original recording was engineered.
Note: This is an experimental feature not yet part of the normal Audacity installation.
Once you have installed this version, you can download and apply AI models via Effects → Deep Learning Effects.
Deep Learning Effects are computationally very intensive. Depending on the model used and your computer, it can take several minutes to hours to apply the effect to a single song. It is highly recommended to test out whether the model is satisfactory on a short section (less than 10 seconds) before applying it to an entire track.
The setup program may return one of the following exit codes:
Exit code | Definition |
---|
Before returning an exit code of 1, 3 or 4 an error message explaining the problem will normally be displayed.
Future versions may return additional exit codes, so applications checking the exit code should be programmed to handle unexpected exit codes gracefully. Any non-zero exit code indicates that Setup was not run to completion.
This page is an introduction to creating background beats and audio loops from a pre-existing audio file.
Audio loops are a type of music that plays a few bars on repeat over and over. They can be created by taking a sample out of pre-existing content and looping it seamlessly.
To enable playback looping, simply click onto the loop button (1). When you do this, you'll note the blue looping region appear in the timeline (2). You can move the region and it's in and out point individually by dragging it.
Tip: You can always create a new region by dragging anywhere outside the existing region within the timeline.
When making a loop out of music, you often will be able to see repetitions in the waveform as your source material will probably contain some loop already (for example a drummer playing the same beat throughout the song). You can use these to roughly find good looping regions and position your looping region above it.
Notes:
If you're having trouble finding a good region with a stereo track, you may want to convert it to mono first: Tracks > Mix > Mix Stereo to Mono
When positioning your loop region, try to aim just before the peaks. Doing that may allow you to skip finetuning altogether.
You can adjust the looping region even when playback is on.
Best practice: Set your looping points at a zero crossing, where the waveform (blue line) crosses 0 (black line):
Once your loop sounds right, you can select it's length in the waveform. A yellow line will appear when your cursor is lined up with the loop region properly. Once you have made the selection, you now can simply right-click > Split Clip (Ctrl+I, Cmd+I
).
Once you have the clip, you can copy-paste it anywhere in your project.
Tip: If you want to use the clip on repeat, use Effect > Repeat.

Edit Steps lists the sequence of commands in order of first to last (End) for the Macro selected in the box to left.
To create an audio file as part of the Macro process you must include an "Export" command (such as ).
The full list of all commands, with descriptions, is available at .
- most commonly useful scriptables.
- less commonly useful scriptables, but also including Select and Set Track, which combine functionality of several scriptables.
If you have previously created for an effect you can use the Use Preset to select one for use with that effect in the Macro.
Many of the other commands provide a simple GUI comprised of checkboxes and text entry boxes. Typical examples can be seen in the and menus.
See for details of naming and location of exported files.
There is also a special Export command which enables you to export to a specific target file and format. When using Export2 you have to give the full file name (including path and filename extension).
The Export as MP3 56k before and Export as MP3 56k after commands can be used respectively to export "before" and "after" files at 56 kbps at any point in the Macro processing. This allows you to compare the result of one or more effects, or provide files for different purposes with and without a particular effect.
Using the Expand button on this reduced dialog will return you to the full dialog.
For more details see the page.
See for details of how these two buttons operate.
See the page for examples of using Macros.
To resolve these errors, ensure you have compatible versions of all required plugins and that the plugins are . If necessary, use the Manage Macros dialog to delete the command that fails then insert a replacement command for the same effect from the Select Command dialog.
If you fail noise, then the process can be a great deal more interesting. See below.

The effects in the Macro are applied to the region of in the selected . Usually the selected Macro would not include an command so as to use the greater flexibility of the .
If an export command is included in the Macro, the entire project audio is exported irrespective of track or region selection. Therefore if the project contains multiple audio tracks, they will be together, unless any of the tracks are muted on the .
If the project has been Saved, then the exported files will be saved in a folder named macro-output. The macro-output folder will be in the location specified in .
If the audio in the project came from an imported file as its initial step (that is, it is a named project), the macro-output folder will also be in the location specified in .
If the project has not been saved and is un-named, the normal dialog will appear enabling you to choose the name and location of the exported file.
The typical purpose of this option is batch processing - apply the Macro to multiple audio files so as to apply one or more effects to them, and/or convert them to another file format. You can convert from any file format to WAV, MP3, OGG or FLAC.
If you already have audio in the current project window, you must save and close that project using File > before applying a Macro to files.
You cannot process (for example, 5.1 surround sound files) using Macros, even if has been set to "Use custom mix". Any multi-channel files you import will be mixed down on export.
The exported files will be saved in a folder named "macro-output" in the folder specified in the Macro output field in . The original files are not altered.
When a Macro is applied to files, the only option is to import and process the entire file. Thus the entire file will be exported unless an action or effect in the Macro (such as or ) removes some audio.
If modifying the audio before exporting, the function may be useful to select audio to remove or modify.
Some optional have parameters to and Nyquist can do calculations too, so it may be helpful to use Nyquist plugins from within a macro.

This article only applies to Audacity versions up to 2.4.2.
If Audacity crashes or the computer loses power, Audacity should normally recover the projects automatically when you restart. The steps on this page describe how to recover audio from the project's _data folder or Audacity's temporary folder if:
Automatic Crash Recovery does not work correctly
You saved a project without apparent crash, but Audacity was shut down before the AUP project file was written or you do not have a usable AUP file.
The steps on this page will only recover unedited recordings (and stereo recordings may be recovered with sections of left and right channel in the wrong channel).
Do not close or save the project if the automatic crash recovery fails to properly recover your project.
If you need to shut down the computer before manually fixing an incorrect Automatic Crash Recovery, force quit Audacity in the system task manager. This will preserve the temporary data for next launch of Audacity.
If you had successfully saved the project just before the crash, it may be simpler to discard the unsaved project in the Automatic Crash Recovery dialog then open the saved AUP file.
If you saved an AUP project file, the _data folder you need to recover from will be in the directory to which you originally saved the AUP file.
If you never saved an AUP project file, you need to recover from Audacity's temporary folder. You can see the exact location in Directories Preferences, otherwise you can see the location in the "TempDir" line in the audacity.cfg settings file. By default the Audacity temporary folder should be as follows.
Windows: C:\Users\<your username>\AppData\Local\Audacity\SessionData
Mac: /Users/<your username>/Library/Application Support/audacity/SessionData
GNU/Linux: /var/tmp/audacity-<your username>
If you are upgrading from previous Audacity, that version's temporary directory may be changed to the relevant safe location above if the previous location was known to be prone to deletion by cleanup applications or system restart.
Tip: In order to see the default location of the Audacity temp folder on Windows or Mac you need to show hidden files and folders or type the folder location into your file manager's address bar.
In the tree on the left of Explorer, double-click "Users" then double-click your username, then on the right, open the AppData or Application Data folder, then the "Local" or "Locale Settings" folder and finally the "Temp" folder.
If you cannot see those folders, you can type %localappdata% into the Explorer address bar then look for the "Temp" folder. Otherwise, see how to show hidden files and folders.
Open Finder, use the "Go" menu, choose "Go to Folder" and type the required path.
If that does not work, try to make the Finder show its hidden files and folders by entering the following commands in the terminal:
If you only have a few AU files to recover, use the "Import Audio" command to open all the .au files from the Audacity temporary folder or project _data folder. Use shift-click or control-click to select multiple files. The files will be in approximately 6-second chunks and will be on separate tracks in the Audacity screen. Files from stereo tracks will alternate between left and right channels.
Click in the Track Control Panel (by the Mute/Solo buttons) of the topmost track.
Shortcut Z
or Select > Region > Ends to Zero Crossings.
Edit > Remove Special > Trim.
Click in the Track Control Panel of the first track you want to join to the topmost track.
Shortcut Z or Edit > Find Zero Crossings.
Shortcut Z or Select > Region > Ends to Zero Crossings.
Click after the end of the topmost track.
Press End on the keyboard.
Click Edit > Paste and the cut track will attach to the end of the topmost track.
Repeat as necessary to join all the tracks onto the topmost track.
Play the result.
Cut and paste as needed if any files are found to be in the wrong order or the wrong channel.
Tools written for legacy Audacity 1.2 can automate data recovery.
All these utilities require the .au files to be input in consecutive alphanumerical order. Audacity names files randomly so files will need to renamed.
Open Audacity's temporary or project _data folder in your system file manager. Sort the files by timestamp order (earliest first), then rename them using a consecutive alphanumerical sequence, lowest number first. An arrangement looking something like this should work:
b001.au 15:56:02 b002.au 15:56:02 b003.au 15:56:10 b004.au 15:56:10
On Windows, Explorer cannot rename to a sequence acceptable to the recovery tools. You can use instead the Mass Rename tool in the 21-day trial Professional or Ultimate versions of xplorer2. These versions will let you recover an unedited stereo recording with exact allocation of left and right channels, if Windows is running the NTFS file system. The free version of xplorer2 cannot guarantee correct channel allocation.
(only in the Professional and Ultimate versions) Click View > Raw Contents to enable maximum date resolution.
Open the required folder in xplorer2 and sort the .au files by time modified as above.
Ctrl + A to select all the files.
File > Mass Rename.
In the "Mass Rename Wizard", click in "Target name template" and type the letter e with a $ after the letter. For example, e$0001.au will rename the files to e0001.au, e0002.au and so on. Use enough zeros in the file name so that all the .au files will have the same number of digits.
Press "Preview", and if the preview looks correct, hit "Rename"
On Mac, try Applications > Automator.
On Linux, try the file manager Thunar included in the xfce desktop See here for help running Thunar on the Ubuntu desktop.
Open a terminal then "cd" into the directory that contains the .AU files.
Type the following command in a terminal to sort and rename the files into numerical timestamp order:
mkdir "renamed" | find -type f -name "*.au" -printf "cp %h/%f renamed/%h/%TY%Tm%Td-%TH%TM%TS_%f\n"|sh
The file names produced in the "renamed" folder are not in a consecutive sequence suitable for the Audacity recovery utilities. Instead, use the Nyquist plugin Append Import to import the files end-to-end into Audacity automatically in file name order.
There is a 2 GB maximum size for any WAV file created from the reconstructed temporary files. This implies no more than 2000 .au files can be recovered. Sometimes (probably due to bugs in the utilities) there can be errors when recovering only 1000 or so files. In that case you would need to split the .au files in the temporary or_data folder into two or more folders, each containing consecutively numbered files, and recover a separate WAV file from each folder.
Recovery of unedited mono recordings should be correct in most cases.
Recovery of unedited stereo recordings may recover with transposed left/right channels in places. Channel allocation will only be correct if you are using the NTFS (Windows) or ext 4 (Linux) file system and if your file manager supports sufficiently fine date resolution (see the Windows example above). This is because the files for each channel may have timestamps that are too close together to be correctly distinguished by other file systems.
If any of the project data has been edited, it is unlikely to recover correctly.
There is no implication that these tools will necessarily do what you want, nor have they necessarily been tested by Audacity Team.
audacity_rescue.sh
This shell script can reassemble a few thousand .au files. It may be simpler to apply (at a bash terminal) than some of the solutions mentioned on this page, particularly for mono recordings.
Using SoX, make a copy of the temp directory and its files from a mono recording:
cp -r /tmp/audacity1.2-jbn ~/rescue
Convert the AU files into raw (headerless) files. The files must already be time-sorted and numbered with leading zeroes:
for f in *.au ; do sox ${f} -t raw ${f}.raw ; done
Concatenate the raw files together to make one long raw file. Concatenating the AU files together (each with its own header) would produce noise at the joins between each AU file.
cat *.raw > bigfile.raw
Finally, import the raw file into Audacity specifying the appropriate encoding, endianness, channels and sample rate.
You can reset Audacity by going to the following menus:
To reset the toolbars only: View -> Toolbars -> Reset Toolbars
To reset everything: Tools -> Reset Configuration
If you cannot open Audacity or want a more thorough cleanup, you can also delete the configuration files manually. They can be found in the following locations:
Windows: C:\Users\<yourname>\AppData\Roaming\audacity\
macOS: ~/Library/Application Support/audacity/
Linux: ~/.config/audacity/
Additionally, the XDG folders ~/.cache/audacity
, ~/.local/share/audacity
and ~/.local/state/audacity
are used on Linux.
Hint: These folders usually are hidden by default. You may need to show hidden files, or access their path directly, to access them.
You can delete all contents of the folder to get Audacity back to "factory settings". Alternatively, you can also only delete certain elements of it:
audacity.cfg is responsible for all preferences
pluginregistry.cfg contains a registry of all plugins and whether they can be used.
pluginsettings.cfg contains last used settings of effects as well as user presets.
Additionally, you may find some other files and folders there, eg. for macros, custom themes or plugins. These can also be deleted though, typically deleting the audacity.cfg and pluginregistry.cfg is enough in most troubleshooting scenarios.
There are several ways to contribute to Audacity. All of them tremendously help out other Audacity users.
These are the rules designed to give the entire user guide a somewhat unified style. You may apply them with some freedom.
The goal of the user guide is to provide explanations on how to perform various tasks in Audacity.
Documenting features seems like the obvious thing to do: Audacity has various menus, so better have a list of what every option in that menu does. However, this leads to the situation where some pages are completely unfindable as a reader already needs to know where certain options are in the menu in order to find out what the page would be called. For example, the feature containing the slider for the recording and playback volumes is called Mixer Toolbar. But nobody except the people most intimately familiar with Audacity know it's called that!
To combat this, try to write your guides as a way towards a goal, or a task. The above example, instead of naming the page after the feature, name it after the task it does, so: Setting recording and playback levels
Tasks aren't necessarily tied to individual features. For example, Noise reduction & removal can talk about several tools as once as they all are means towards a common goal.
If a feature has many different modes or options that are unrelated to the task you're describing, avoid making long lists of what all the feature can do. Focus on the task-related ones instead.
If a feature has several ways to access it, use the most accessible option. For example, for an "how to play audio" article, simply mention the big green play button and the shortcut Space
. Don't also mention Transport > Playing > Play/Stop.
There are some exceptions to this, especially when documenting more "advanced" features like Macros which need extensive guiding about how to operate it. Instead of a linear "go here, then here and there, and then you're done", split them up into sub-tasks (for macros: creating macros, editing macros, etc.) and keep these unrelated tasks on one page. Avoid breaking it down to the point where you are explaining individual buttons (don't say "the cancel
button cancels the effect without applying it")
Rule of thumb: If a feature is easy to use, but hard to find, document it like a task, ie answering the question "how do I do x". If a feature is hard to use, document how to use the feature as a series of sub-tasks if possible.
Audacity's user base consists largely of casual users. As such, you can't expect the readers of your guide to understand even fairly common audio terms (for example: compressor or loudness vs volume), unless it's directly connected to the topic you're writing about.
For example, if you write a guide about compressing and expanding audio, you don't need to hold yourself up on explaining what a compressor is, since the only people who'll ever end up reading that guide are people who already know about that. However, if you were to mention a compressor on a page about general audio editing, you would need to explain what a compressor is good for.
That said: If it's possible to describe a feature without needing to resort to lingo, use it even if it's slightly less accurate. For example, "punch-in repair" would be the accurate term for Re-recording a section, but also is way harder to understand and thus to find.
While there's a lot of things you can write about in relation to Audacity, keep in mind that this site is focused on user guides (or how-to guides, or tutorials - they all have the same idea). We want to minimize work on contributors while maximizing impact, so guides should be kept as general as possible. Only use qualifiers such as "for podcasters" or "for musicians" if their use case shares almost no resemblance to what everyone else would be doing anyway.
Caution: The following topics are out of scope:
Audio-related content beyond Audacity, like: "how to build a quiet recording booth"
Reviews and recommendations of software/plugins/...
Technical documentation about the internals of Audacity.
You can address the reader directly ("you"). You should remain impartial in the process though, so no "I" or "my".
The overall tone should be friendly but not patronizing, and the language should have a healthy middleground between casual and technical.
Titles should reflect the task you're trying to teach. For example, if you're teaching how to add reverb, the title should be "Adding reverb"
The title should be concise (try keeping it below 60 characters).
Page titles should be written in sentence case. So generally, the first is capitalized while everything else is not, except proper nouns and acronyms ("Audacity", "FFMPEG").
Note: When the title explicitly refers to an option within Audacity itself, use the spelling found inside Audacity. So for example, "Using the Noise Reduction effect" would have "noise reduction" capitalized, but "Reducing noise in Audacity" would not.
Underneath the title is a field for page descriptions. These descriptions are the first thing users see of the article when looking at Google, or seeing an embed to it somewhere.
As such, they should give a good summary of what the page is going to be: In a few words, how will a goal be achieved? What features will be used?
Instructions should be written in a step-by-step list where useful. For example:
Do This
then that
then a third thing
If you need to interrupt the steps for explanations, you can either do
Do this
then that (shift+enter) Note: This is an explanation on a new line
then a third thing
If instructions are different depending on the operating system or other factors, you can use tabs, like this:
Windows Instructions
MacOS instructions
Linux instructions
Tabs aren't part of standard Markdown, so they probably won't show up properly if you're using github or a local editor. They'll show up just fine on Gitbook though.
Note: Tabs are quite big blocks, visually speaking. When using them, make sure that what you're showcasing is worth this space. For example, if you're just saying that undo is Ctrl+z on Windows and Linux, you can just put brackets behind it for the mac instructions - "press Ctrl+z (Cmd+z)"
If a task has a main way of working, but may benefit from additional context, you can use the Expandable block:
You can take screenshots using the clipping tool or tools like ShareX. ShareX has the advantage that it has built-in tools like arrows, step-by-step bubbles and labels which can help you visualize several steps at once.
With images, there always is a tradeoff between easy maintainability, clarity and context. So crop them as much as possible without losing important context, and use them in a way that makes updating them as painless as possible.
Gitbook offers 4 types of info boxes.
Info: Use these for information which is useful to know, but not necessary to fulfill the task. These boxes should be started with
Info:, Note: or Tip: for general additional information
Shortcut:Key + Combination
for shortcuts
Warning: Use these for information where things might go wrong and the user might get undesired results. These boxes should be started with
Caution: or Warning: depending on which feels more appropriate in terms of urgency
Danger: Use these for super important information only, where ignoring the danger box would lead the user to irreparable damages (lost data, broken audio, ...). These boxes should be started with
Danger: for super important info
NEVER or DON'T if you need to go straight into the warning, where "danger" would look silly.
Success: Use these for things the reader should do. These should be started with
Best practice: or Do: for best practices
Checklist: if you want to provide a checklist
These info boxes aren't part of standard markdown, so if you're not using gitbook itself, but edit through Github or a local editor, they will look a bit silly in your preview (but show up correctly here).
If an image is worth a thousand words, a video tutorial can be worth a million: At it's best, it can tell the entire story the written guide would make in a way that always has all necessary context and requires no lengthy description of where to find things.
However, video tutorials can go out-of-date incredibly quickly and then cause a lot of confusion among viewers.
Because of this, a video tutorial must follow these rules to be added to an Audacity Support page:
The video must clearly state what version of Audacity it's referring to in the beginning.
The video must be in the language of the Audacity Support page it's meant to be embedded in. Right now, that's English only.
The video must be a dedicated Audacity tutorial or how-to guide.
The video must refer to Audacity Support as the place to get up-to-date help from.
The video must not contain a sponsorship read, and it is preferred to have the video completely ad-free.
The video should be licensed Creative Commons-Attribution (see YouTube help). This way, if your video goes out of date, other people can update only the part of your video that goes out of date.
The video and the Audacity Support page it's supposed to be embedded in should match the steps they take. If the video tutorials goes on a tangent unrelated to the initial task, the written guide may omit the tangent and instead place the contents of the tangent in a "See also" section.
The following points are considered best practice for video tutorials:
Start with the purpose and version number and then go straight into the content: "To do XYZ in Audacity 4.2.0, first go to..."
Use a script which you follow when making your video. This will automatically eliminate the following two points, and also get you a long way towards making subtitles.
Avoid going off-topic, eg "hey guys, and welcome back to another video! my sister's aunt's nephew requested I make a tutorial so he can cook his eggs using Audacity to which I said..."
Go through your tutorial linearly step-by-step, and avoid jumping back to earlier sections much later in the video. For example, if you are in Step 9 already, jumping back with a "oh yeah, I forgot to add that in Step 3, you need to also do..." is majorly confusing.
Add subtitles to your videos. Not only do they make your tutorial more accessible to deaf people, they also are useful to people who have trouble understanding your dialect or accent, or who want to auto-translate the subtitles into their own language.
Use chapters on YouTube to mark major steps in your video. They work by putting the following in your video description:
This is a living document. It contains the best practices, as determined by the community. Feel free to discuss additions and changes on the discussions page, or in the discord.

Using the Audacity Project Tools to recover corrupted projects
This article addresses the following error codes in Audacity:
Error code 11
Error code 13
Error code 101
"Audacity failed to read a file in C:" (or D:, E:, ...)
Make sure you use the latest version of Audacity. See Downloading & installing Audacity for more information.
Sometimes, just opening the file in the latest version automatically recovers the project. If not, proceed with the following steps:
First, download the latest version of the Audacity Project Tools:
After downloading, follow the instructions relevant to your system. Note: macOS is not supported yet.
Caution: Make sure you have plenty of space left on your computer. You will need roughly 4 times the size of your .aup3 for a successful recovery. If you have a 10GB file, you should have at least 40GB available.
In your Downloads folder, create a new sub-folder "AudRepair".
Unzip the audacity-project-tools zip which you downloaded
Move the two .exe files from the unzipped folder into AudRepair.
Copy your defective .aup3 project file into the AudRepair folder.
Rename the file to broken.aup3
.
Press Windows-key + R
, and type cmd
. A (black) cmd screen will appear.
Navigate to your AudRepair folder by typing cd Downloads\AudRepair
and pressing Enter
.
Type dir
and press Enter
. The following three files should be listed: audacity-project-tools.exe
, broken.aup3
, and sqlite3.exe
Type audacity-project-tools -drop_autosave broken.aup3
and press Enter
.
The message "Project requires Audacity 3.0.0" will appear.
When the command prompt (C:\Users\(yourname)\Downloads\AudRepair\>
) reappears, type dir
again.
If a broken.recovered.aup3
file appears, open it in Audacity.
If that file works as expected, go to File -> Save As... and save it to your usual location. The recovery process is now over, you can continue working as normal.
If that file does not appear, or is still broken, continue with the following steps:
Type audacity-project-tools -recover_db -recover_project broken.aup3
and press Enter
.
The messages "Project requires Audacity 3.0.0
", and "Using 'sqlite3.exe' for recovery
" will appear. Later the message "Executing query #xxxx....
" will appear as the rescued file is being recreated.
Note: This process can take quite a while depending on your specific machine. There is no status (or % completion) indicator, so you just have to be patient.
You should plan 15-30 minutes per GB, though it may be faster if you have a fast PC.
Keep an eye on available disk space.
Due to a glitch, sometimes a single character can appear when the program is done, eg "z
". If this happens, simply press Backspace.
When the process completes, your should be able to open the "broken.recovered.aup3" in Audacity. The message "File not saved properly" will appear the first time you open the recovered project. This is normal and you can ignore this message.
If the messages "Invalid block xxxx: Block not found
", check to see if some audio was silenced - typically near your most recent edits. Usually these messages are spurious.
In your downloads folder, create a new sub-folder called "AudRepair".
Unzip the audacity-project-tools ZIP file that you downloaded
Move the unzipped files into AudRepair
Copy your defective .aup3 project file into AudRepair
Rename the .aup3 file to broken.aup3
Open the Terminal or Konsole program.
Navigate to the AudRepair folder by typing cd ~/Downloads/AudRepair
and pressing Enter
Type ls
and press Enter
. **** The following three files should be listed: audacity-project-tools
, broken.aup3
and sqlite3
Make the audacity project tools and sqlite3 executable by typing chmod +x audacity-project-tools sqlite3
and pressing Enter
.
Type ./audacity-project-tools -drop_autosave broken.aup3
and press Enter
.
The message "Project requires Audacity 3.0.0" will appear.
When the command prompt (you@pc:~/Downloads/AudRepair$
) reappears, type ls again.
If a broken.recovered.aup3
file appears, open it in Audacity.
If that file works as expected, go to File -> Save As... and save it to your usual location. The recovery process is now over, you can continue working as normal.
If that file does not appear, or is still broken, continue with the following steps:
Type ./audacity-project-tools -recover_db -recover_project broken.aup3
and press Enter
.
The messages "Project requires Audacity 3.0.0
", and "Using 'sqlite3' for recovery
" will appear. Later the message "Executing query #xxxx....
" will appear as the rescued file is being recreated.
Note: This process can take quite a while depending on your specific machine. There is no status (or % completion) indicator, so you just have to be patient.
You should plan 15-30 minutes per GB, though it may be faster if you have a fast PC.
Keep an eye on available disk space.
Due to a glitch, sometimes a single character can appear when the program is done, eg "z
". If this happens, simply press Backspace.
When the process completes, your should be able to open the "broken.recovered.aup3" in Audacity. The message "File not saved properly" will appear the first time you open the recovered project. This is normal and you can ignore this message.
If the messages "Invalid block xxxx: Block not found
", check to see if some audio was silenced - typically near your most recent edits. Usually these messages are spurious.
Note:
There is no guarantee that all content will be able to be restored, or any at all.
Some additional commands for the Audacity Project Tools can be found on Github.
If a section of audio is missing, you may need to manually re-record it. See Re-recording a section for more information.
If Audacity shows you an error message when trying to record or playback audio start using Transport > Rescan Audio Devices to update the list of devices.
After rescanning audio devices try selecting a different host using the Audio Setup button and make sure the desired device is selected as your Recording or Playback Device
If the error is still present try changing the Project Rate to a different value:
Verify that the Recording Meter Toolbar and the Playback Meter Toolbar sliders are set to an appropiate level. Place the mouse cursor over the meter and Audacity will display the corresponding level
Some operating systems may block access to the microphone for untrusted apps. You need to allow microphone access for Audacity in order to record.
Open Settings
Go to Privacy or Privacy & Security
Go to Microphone
Toggle on Microphone Access, Allow apps to access your microphone, and, if available, Let desktop apps access your microphone
On your Mac, choose Apple menu > System Preferences then click Security & Privacy in the left-hand menu and the click the Privacy tab.
Click Microphone in the left-hand menu.
Select the checkbox next to an application (Audacity) to allow it to access the microphone.
If you have installed Audacity as a Snap or Flatpak, you may need to go to the System settings > Application settings
If your microphone is not listed under the Audio Setup > Recording Device dropdown, select Transport > Rescan Audio Devices to refresh the list of recording devices. If it still doesn't appear after rescanning it could be disabled in your operating system audio settings. You need to enable it in order to record.
Open the Sound control panel and select the Recording tab
Make sure that Show Disabled Devices is selected
Look for your microphone and Enable it
After enabling your microphone use the Audacity Transport - Rescan Audio Devices option to update the list of available devices.
It is recommended to update drivers for audio devices you are using. The way to do that depends on the specific device but in general it is recommended to visit the manufacturer support website.
Some audio devices install a complementary application that provides options to check for firmware and driver updates.
Windows users can try to manually update drivers using Device Manager, before looking for drivers on the Internet. This is easiest, but may not necessarily find the latest or most appropriate drivers.
Windows 10 / Windows 11: Right click the Start button and select Device Manager
Windows 8 / Windows 7 / Windows Vista: Click Start > Control Panel then using the "Category" view, click "Hardware and Sound", find "Devices and Printers" near the top of the screen then click on "Device Manager" (the last item in the list underneath). "Icons" views have a direct link to Device Manager, as does "Classic View" on Windows Vista only.
Then expand Sound, video and game controllers by clicking on the + sign, right-click over the sound device and click Update driver.
After the update (even if more recent drivers were not found), you should right-click over the device again, click Properties and then on the Driver tab to check the "Driver Provider". You don't want drivers from Microsoft - in most cases these are only generic drivers, not specifically matched to your hardware. This often leads to problems such as not being able to select the correct input, or recordings not being made correctly. These must be replaced with drivers made by the manufacturer of your hardware, so they are correctly matched to that hardware.
If you have now got updated non-Microsoft drivers, try them and see if your recording problem is solved.
Use the Recording Meter Toolbar to check the audio level that Audacity is receiving from the selected Recording Device. Click on the microphone icon to Start/Stop monitoring the audio level.
If there is no level present on the meter check if the microphone is muted in your operating system audio settings:
You can also check if your device provides some physical control to mute or set the audio level.
If the controls on your device are properly set you should check the connections between the computer and the recording device.
Due to a Windows limitation, you cannot use WASAPI on a USB device while listening back on an onboard audio card. Use MME or DirectSound instead, or use the USB device for both the input and output (if possible).
By default Audacity will compensate the latency present in your system by 130 milliseconds. Using this procedure you can estimate and set the proper value for your system.
Note: Latency Compensation is only important for the following recording scenarios:
Overdubbing: recording a new audio track while listening to previously-recorded track(s). You want what you play to be synchronized with the tracks you are listening to.
Punch and roll recording
There is an automated method available now, which is available at https://forum.audacityteam.org/t/latency-test/65001
It's currently in beta, so please leave your feedback in the forum thread
On Windows open the Edit menu and select Preferences... or press Ctrl + P
in your keyboard. On macOS open the Audacity menu and select Preferences... or press Cmd + P
Select Devices in the left pane of the Preferences window
Select the preferred Interface Host: MME or Windows WASAPI should work
Verify your preferred Playback Device is selected
Verify your preferred Recording Device is selected
Set the Latency compensation to 0 (zero) milliseconds
Click OK to save your preferences
Select Recording in the left pane of the Preferences window
Enable Overdub: Check Play other tracks while recording (overdub)
Make sure Software playthrough of input is not checked
Click OK to save your preferences
At the bottom of the Audacity window you will find the Selection toolbar
Disable snapping, if you have it enabled
Select Start and Length of Selection as your selection format
To measure the latency you will need to record the audio from your playback device using your microphone. To do this place your microphone next to your speakers/headphones
Open the Generate menu and select the Rhythm Track... option. Set Number of Measures (bars) to 2 and set the Beat Sound to Ping (short). Click OK to generate the track.
Press Shift + R to record a new track. The rhythm track will be played back and recorded on a new track.
Zoom in so you can see the clicks on the top track and its delayed version on the bottom track
Create a selection that goes from the start of one click to the next
You should see something like this:
You can read the latency directly from the second panel of numbers. In this case it is 0.184 seconds or 184 milliseconds.
Click on Edit > Preferences, click on Devices tab and enter the negative of this number in the Latency compensation box. In this case it would be -184. Press OK to save your preferences.
Delete the second track by clicking the close box in its Track Control Panel
Click in the Track Control Panel of the remaining track to select it
Press Shift + R to record a new track
After the recording is finished Audacity will apply the Latency compensation by pushing the newly-recorded track back by the Latency compensation value.
Note: If you change any of your recording or playback devices (for example, if you change from using the line input port on your computer to using a USB audio interface) or if you use the same device but change the Audio Host in Device Toolbar, then you will need to do this test again. The test you just did only applies for the specific inputs and outputs and host used during the test.
Any page of both support.audacityteam.org and plugins.audacityteam.org can be edited either on Gitbook (see #writing-tutorials-and-user-guides for instructions) or using Markdown syntax on GitHub.
Note: Various formatting options available in Gitbook cannot be previewed on GitHub and most local Markdown editors. Be aware of the differences between
Gitbook-hosted pages (plugins/support.audacityteam.org)
The reverse isn't true however: All Github-flavored markdown is supported in Gitbook.
A link for GitHub is shown either on the right-hand side or in an overflow menu of any page:
Once you are on GitHub, you will see a pencil in the top right of the file.
You now can make your changes to the page.
Best Practice: Frequently switch between the Code and Preview tabs in GitHub to get a general sense of what your edit will look like.
Also, if you haven't already, now is a great time to familiarize yourself with the Style Guide.
Once you are done, press Propose Changes
This brings you to a page where you can review your changes. If you are satisfied, click Create Pull Request.
After you click "create pull request", it will show up on https://github.com/audacity/audacity-support/pulls and await review by an Audacity team member.
You can edit Markdown in any text editor. More advanced editors like VSCode may show useful shortcuts and visualizations for easier and faster editing, but in principle, even the simplest text editors like Windows Notepad can be used to create them.
Caution: Avoid using office suites like Microsoft Word, LibreOffice or Google Docs to edit Markdown. They tend to use very different formatting options, which don't transfer to plain text. As a rule of thumb, if it doesn't save in .txt or .md, it's not the right app to use as a Markdown editor.
To get started, first clone the repository, either using git clone
https://github.com/audacity/audacity-support.git
by clicking the code button on https://github.com/audacity/audacity-support and opening it in GitHub Desktop
Note: You will need to use some form of Git to make a pull request, so just downloading the ZIP will not work.
Once it's cloned, you'll find the files of support.audacityteam.org in the main
branch, and the files of plugins.audacityteam.org in the plugins
branch. Any additional branches have been split off from the main branch to preserve documentation for previous versions of Audacity.
Further information on using git with VScode can be found in the VSCode docs.
Outside from the syntax requirements, there are some more technical things you need to be aware of:
The sidebar menu is handled through SUMMARY.md, not the file structure itself. If you want the page you created to show up in the sidebar, you will need to update this file accordingly. That said: Try to match the structure of SUMMARY.md with the folder structure.
While you technically can work directly in your fork's main/plugins branch, it is highly recommended to make a new branch based on upstream/main
or upstream/plugins
instead for your changes. This way, you can always fast-forward merge the latest changes into your fork.
When updating your fork's side-branches to the latest state of main, rebase it if possible.
Due to licensing restrictions Audacity cannot be distributed with built-in support for ASIO. However You can build Audacity for your personal use and include ASIO support.
Audacity can record and playback audio on your Windows PC using one of the following three alternative interfaces:
MME
Windows DirectSound
Windows WASAPI
ASIO (Audio Stream Input / Output) is an additional proprietary interface to record and playback audio in Microsoft Windows. ASIO bypasses the Windows audio mixing components to provide lower latency direct communication between computer audio software and hardware. Most audio recording interfaces manufacturers provide a driver to support ASIO.
ASIO supports 24-bit sampling which is only otherwise available using or WDM-KS (Windows Driver Model Kernel Streaming). 24-bit sampling allows greater dynamic range, lower theoretical and greater resolution at lower audible volumes.
An unmixed ASIO output is "bit identical" to the original source.
Multiple physical input and output channels of the hardware are accessed over one single device.
Windows interface protocol support multi-channel recording on some sound devices, but not the very low latencies that are possible on ASIO.
A Macro is a sequence of pre-configured commands (mainly effects) in a set order that can be applied automatically to projects or audio files.
Macros in Audacity can be used for:
Batch processing: Apply one or more effects to multiple audio files and export the processed audio into a new file.
To use this select the Apply Macro to: Files... button in the or the dialog.
For more detail on batch processing please see .
Effects automation: where the in the or tracks in the current project is subjected to the same prescribed sequence of effects, and optionally, a file exported from the entire audio.
Macros can contain Select commands to make their own selections as the Macro runs
Effect presets: where selected, commonly used, effects are stored with your preferred settings for quick re-use.
You can manage and apply Macros using the :
Tools > Macros... to manage Macros: them
Tools > Apply Macro > Palette... for a
Tools > Apply Macro > named Macro to
There are some and tips on using them.
Use Tools > Macros... if you need to create a new Macro or to edit an existing Macro.
This dialog is also available directly via Tools > Apply Macro > Palette...
Project applies the selected Macro to the current project.
Files... applies the selected Macro to selected external audio files that are in a single directory.
It is recommended not to process more than 500 files at a time.
Commands that call Effects, Generators, Analyzers or Tools, use the same familiar graphical interface (GUI) as appears when they are used from the normal top level menus.
It is strongly recommended that you set parameters for the commands that you use in a Macro. Otherwise Audacity will use the last-used parameter setting(s) when you ran the effect(s) manually.
Also note carefully that settings used in Macros will not affect or change the last-used parameter settings for any effect when next run manually.
Basically to paraphrase: "What happens in Macros stays in Macros".
You can also edit Exported Macros with a text editor and Import them back in if required.
Windows: Users\<username>\AppData\Roaming\audacity\Macros
Mac: ~/Library/Application Support/audacity/Macros
Linux: ~/.audacity-data/Macros
In order to see the Macros folder on Windows, macOS or GNU/Linux, you must show hidden files and folders or type the folder location into your file manager's address bar.
This page lists features which got removed from Audacity, as well as their replacements.
The Audacity Wiki has been shut down.
You may find the information you were looking for in the following places:
A wikidump of the Audacity Wiki as of March 31, 2023 can be found . It can be accessed and worked with in the same way as .
In Audacity version 3.3.0, the Device preference page has been renamed to Audio Settings.
In Audacity version 3.3.0, the Project Rate has been renamed to Project Sample Rate and moved into the Audio Setup button -> Audio Settings
The Cut, Copy and Paste buttons have been removed from the Edit Toolbar in version 3.2.0.
Audacity version 3.2.3 introduced the Cut/Copy/Paste Toolbar which is disabled by default. Check View > Toolbars > Cut/Copy/Paste Toolbar to enable it.
You can also access the Cut/Copy/Paste functionality in the following ways instead:
Right-click the selected audio and choose Cut/Copy/Paste
In the Edit menu, choose Cut/Copy/Paste
Use shortcuts:
Ctrl+X
is cut (Cmd+X
on macOS)
Ctrl+C
is copy (Cmd+C
on macOS)
Ctrl+V

Gitbook works a bit like a wiki in that you can edit all pages freely, but unlike a wiki, it uses git's "everyone has their own branch" principle. That is to say that the changes you make are independent of everyone else's changes, and won't show up on the main (live) website until the branches are merged.
To some degree, this means that you can do whatever you want in your branch. That said, there's some things which make things easier for everyone involved:
Best practice
Doing so makes it easier to understand what your changes are exactly, and should one of your changes be rejected, most of your other work won't get blocked by it.
Only submit complete pages. Your progress is saved automatically, so if you want to call it for the day, simply close the page and continue the next day. If you accidentally hit "submit", simply start editing again to convert your branch to a draft branch again.

Testing Audacity is one of the best ways to find bugs.
You can download the latest master build from https://audacityteam.org/nightly. These builds reflect the state the master branch. Anything in the master branch has passed at least a quick round of QA to validate that the features the change touched still work for the common use cases.
Before features go into the master branch, they live in pull requests. Each pull request comes with its own builds, available through the "Checks" tab inside the PR and then the "Artifacts" dropdown in the top right. Additionally, you can get builds which are still in development from https://github.com/audacity/audacity/actions. Both methods require a Github account.
Note: When testing pull requests, report any bugs regarding it as a comment inside the pull request.
When you do find something that breaks, make sure to file a bug (or comment on the pull request that introduces the bug if it's unmerged)!
Before each release, a branch is split off master named "release-x.x.x". This release branch contains all features which will be part of the next Audacity release. Bug fixes which go towards this release will be made inside this branch. You can get builds for it via https://github.com/audacity/audacity/actions; the nightly link will continue to give you master branch builds.
During the release process we may designate certain builds as "alpha" or "beta" and release them on https://github.com/audacity/audacity/releases. This is to invite testing from a wider audience.
Audacity comes with some tools to aid you with testing.
See https://manual.audacityteam.org/man/macros.html - these can make it easier for you to do repeated tasks.
Journaling is a feature that records all your actions and lets you replay them. This feature is currently under development and not really ready.
start Audacity in journaling mode, <<TODO: HOW??>> do a certain task, and then close Audacity again. This will generate a journal file, which you can find in <<WHERE>>.
Copy the journal file to a new folder (eg: QA-tests) and name it so that you can easily find it again.

Changelogs and release notes for current versions of Audacity
We maintain a list of free VSTs and similar plugins on plugins.audacityteam.org. You can find, test and add plugins to the list.
To do this, you can get access to the plugins space via https://www.audacityteam.org/gitbook-plugins and then edit the relevant sections.
Exact details can be found here: https://plugins.audacityteam.org/contributing/adding-plugins-to-this-site
Audacity is being developed on Github. Most information necessary to contributing code can be found there, such as building instructions.
Note that Audacity currently is undergoing major restructuring. As such, we can't promise a swift review or merge of any pull requests you make.
As the codebase is over 20 years old, it's not massively beginner-friendly (though this should get better once the refactor is complete). If you are new to C++, you may want to try doing something else instead first - developing a plugin might be an idea.

Translating Audacity is the best way to get involved right in Audacity's UI without having to code.
Audacity is translated into multiple languages by volunteers across the world. If you want to contribute to translation please join the audacity-translation mailing list and read the instructions below.
Before joining the Audacity project in Transifex please subscribe to the audacity-translation mailing list and check the status of the translation you would like to contribute to with others members of the list.
You can find and join the Audacity project at https://explore.transifex.com/klyok/audacity/
Click the JOIN THIS PROJECT button on the right side.
Select the language you would like to contribute to from the dropdown.
Click Join Project (if the language is Available to join) or Request Language if the language you want to contribute to is not available yet.
Once you have been approved as a translator you will receive a notification by email. After that you will see the project in your Dashboard and you can start to contribute.
Click Translate at the top right side
Select Audacity from the Resource Overview panel to start editing
Select the string to translate and type the corresponding translation
Click Save Translation and select the next string to translate.
Audacity uses GitHub and you can explore the available translations at https://github.com/audacity/audacity/tree/master/locale
Each language translation is stored in a PO file. For example it.po is the Italian translation and ko.po is the Korean translation.
To download a PO file from GitHub click on the link for the .po file for your language. On the page you come to, right-click the Raw button and then select then Save target or Save link as. Select the location to place the PO file.
Use the wxWidgets languageinfo.cpp file as a reference to the list of translated languages.
These are some programs you can use to edit PO files:
The following instructions use poEdit 3.1.1 to illustrate the process of translation
If there is no translation PO file for your language create a new one using the following steps:
Download the audacity.pot file from Audacity GitHub
Open poEdit and select Create new... (Create new translation from POT Template)
Select the audacity.pot file and click on Open
poEdit will ask you about the Translation Language. Select the language from the dropdown and click OK.
Select Translation > Properties... and verify that the Character option is set to UTF-8 otherwise poEdit will not save any translations with non-English characters.
Translate each one of the entries using the Translation textbox
Select File > Save to save as a PO file. Select a destination folder and type a name for the file. Click on Save. poEdit will save a .po file plus a .mo file for use in Audacity.
The following instructions use poEdit 3.1.1 to illustrate the process of translation
If you want to update an existing translation
Download the PO file for your language, for example it.po or open a previously translated PO file from your computer.
Download the audacity.pot file from Audacity GitHub
Open poEdit and select Browse files (Open and edit translation files)
Select the existing PO file for your language and click on Open
Select Translation > Update from POT file... and look for the audacity.pot file you downloaded previously. This will update your PO file with the latest strings from the downloaded POT file.
Translate each one of the entries using the Translation textbox
Select File > Save to save as a PO file. Select a destination folder and type a name for the file. Click on Save. poEdit will save a .po file plus a .mo file for use in Audacity.
To submit a translation, please send the completed .po file to the audacity-translation mailing list. A member of Audacity Team will commit the file and send a message to the list confirming this.
You can get an up-to-date alpha version of Audacity, NOT suitable for production use, but good for checking translations on, in the nightly version: https://audacityteam.org/nightly. From there, you’ll find there are choices of builds for different platforms. Download the right one for your platform.
On Windows, open the “Languages” directory inside the unzipped Audacity folder, then open the directory with the same name as your .po file. On Mac OS X, right-click or control-click over Audacity.app > Show Package Contents then open the relevant LPROJ directory inside the “Resources” directory. On GNU/Linux, open the relevant “locale” directory in usr/share/ or usr/local/share.
If creating a new translation, create a new directory for your language using the correct language code from the wxWidgets languageinfo.cpp file. For example, the code for Punjabi is “pa”, so on Windows, create “Audacity\Languages\pa”.
Rename the saved .mo file to “Audacity.mo”, and paste it into the directory you opened or created.
Open Audacity and in Preferences > Interface, choose your language and click OK. You should now see your translations.
Please read Translating Audacity for more tips on translating the Audacity source code, and to learn how the Audacity software is translated.

Audacity 3.1 was released on 27. October 2021
Audacity 3.1 replaces all previous versions.
The old Time Shift Tool has been replaced by Clip handles. Clip handles are the rounded corners above the clip which feature the clip title. You can move clips around by simply clicking and dragging the clip handle, and you can rename clips by double-clicking the clip handle.
Label tracks don't feature clip handles, but they can be moved around just the same: Simply click on the label (the bar for region labels, the circle for point labels) and drag them to their new place.
Audacity now can trim clips non-destructively by dragging the upper edge of a clip. This means that you can make clips shorter, then do some edits and then decide it should be longer anyway - the data will still be there. Copy-pasting the trimmed clip also will have that info available!
Audacity now features a new playback looping button. Enabling it will mark the current selection as a looping region, in which the playback will loop. You then can edit and select independently of the looping region. This feature replaces the previous Shift+Play behavior.
When looping is enabled, you can press Shift+Play to only play the looping region once.
Since it's conception in 2000, Audacity had cross-platform support of both Windows, macOS and Linux as it's goal. But macOS at the time didn't have a right-click, so to not hide features from mac users, Audacity didn't have any right-click context menus. The situation has changed since then, and there no longer is anything hindering right-click context menus, so they now have been added to a few places, such as in the waveform of clips and the empty (dark grey) space outside of tracks, providing relevant options right there.
In the preferences, is now disabled by default. This makes multi-track editing easier (even if you're not using Sync Lock). You may now see an error saying that there isn't enough space when pasting clips in-between other clips though, so if that happens to you too frequently, you may want to turn it back on.
The spectrogram defaults have been changed: scale type to Mel (was Linear), top of scale to 20000 Hz (was 8000 Hz), window size to 2048 (was 1024), and zero padding to 2 (was 1).
Since Audacity 3.0.3, there have been two hot-fix releases (3.0.4 and 3.0.5), both fixing a bug each which could lead to data corruption. Thanks to the automatic updates introduced in 3.0.3, we actually could make these hotfixes and be reasonably certain that they'd actually reach users and potentially avert data loss.
In addition, we fixed a number of bugs, from the very small (the play button had 1-2px cut off at the bottom) to some larger ones (especially crashes/bouncing balls of death). Some more details can be found below.
Context menus have been added in more places.
In the preferences, Tracks > Track behaviors > Editing a clip can move other clips is now disabled by default
The spectrogram defaults have been changed: scale type to Mel (was Linear), top of scale to 20000 Hz (was 8000 Hz), window size to 2048 (was 1024), and zero padding to 2 (was 1).
The main volume controls no longer change the system volume.
Raw Import now will remember the previously used settings. Automatic detection of the format now is a button.
A journaling feature has been added for QA purposes.
Generate > Tone now supports triangle waves.
There now exist "What's new" screens for the update and welcome dialogs.
Timeline Quick Play for regions and locked regions have been replaced by playback looping.
The shortcut to rename labels and clip names has temporarily been hardcoded to Ctrl+F2.
This conflicts with the default xfce shortcut to change workspaces.
FFMPEG now supports avformat 55, 57 and 58.
PortAudio has been updated to version 19.7 and devendored (so it can be built against 19.6).
Several libraries (expat, libsndfile, ...) have been devendored. The CMakeLists.txt lists which versions we build against.
There are some 50 issues closed labeled as bug. Among them:
AppImages support localization. #1382
Progress bars for Nyquist generators have been made more accurate. #1856
Rhythm tracks can no longer drift off-time by 2ms over 9 minutes; they're now sample-accurate. #1853
The play button has regained a pixel or two to become a triangle once more. #1792
Auto Duck has been made way more accurate and should no longer miss sections above the threshold. #1389
The manual now only is included in the executable once #1917
Shift-clicking a menu item no longer opens the settings menu #1358
FFMPEG no longer segfaults ALSA #1170
Audacity no longer crashes when macros output directory is set to C:\ #1174
A bouncing ball of death problem has been fixed #1312

Audacity 3.0.4 was released on 24. Aug 2021.
Audacity 3.0.4 replaces all previous versions.
This is a hotfix release that fixes a bug with envelope points, which could multiply uncontrollably and cause Audacity to crash. In particular:
#1476: Envelope points are multiplied when using Filter Curve EQ or Graphic EQ
#1477: Filter Curve EQ will crash if there is an envelope point outside of the selection
This fix re-introduces an earlier, but way less destructive bug:
bugzilla 208 / #1500: Some effects delete Envelope Control Points, or do not move them when timeline changes

This page is an overview of prominent new functionality that has been introduced in Audacity 2.4.2
Version 2.4.2 is primarily a maintenance release for bug-fixing, so there are not many new features.
Details of all the major changes since 2.4.1 can be found in Audacity Release Notes 2.4.2.
A new command has been added to the Help menu: Help > Reset Configuration.
This resets your Audacity configuration, preferences (except Extended Import), export settings and toolbars, to default settings.
Be aware that this command acts immediately with no dialog and no choice of actions or chance to abort.
Undo is not available for this command.
User presets in Effects, Generators and Analyzers are left untouched, as are any Macros you may have created and plug-ins.
Audacity now supports LAME's gapless playback info, allowing MP3s to be exported and imported without additional padding.
Other applications that support the LAME tag, for example audio player applications, will be able to read MP3 files exported by Audacity without the padding.
In less than a month we have foxed a further 29 bugs in this maintenance release.
Here is a small selection of some of the most important.
P1 2442 - Windows: Crash when importing (or editing) to a disk with insufficient disk space available
P1 2449 - Mac: Attempting to export as M4A(AAC) yields an FFmpeg error message

Audacity 2.4.2 - detailed release notes for this release of Audacity
Audacity 3.0.3 was released on the 26th of July, 2021
Key improvements:
Windows version is now 64-bit
(Note: 32-bit plugins will not work on 64-bit Audacity)
A 32-bit build of 3.0.3 remains available for download
Improved default spectrogram colors
We now provide an official binary for Linux in the form of an AppImage
Update checking: Audacity can now check to see if there is a newer version available
Error reporting: this is a new dialog where users can choose to send us the details of a serious error
Multiple bugs fixed
If you are a user of previous Audacity versions on Windows and had installed the optional FFmpeg library then you must now install the 64-bit versions of the FFmpeg library.
Otherwise your imports and exports that depend upon FFmpeg will no longer work.
See Installing FFmpeg for Windows for installation details.

Below are listed what we believe are the most common and important issues with 2.4.2 for most users.
Accessibility
Far less of Audacity is properly accessible to visually impaired users than we would like. Currently the best supported platform for accessibility is Windows. We lost a lot of custom accessibility programming when we had to move to a more recent version of the wxWidgets library.
Internationalization
Audacity is only partially translated in many languages. We also have some issues, for example, with Right-To-Left Languages.

Audacity 3.2 was released on 22. Sep 2022
Added a new Effects button to the tracks menu, allowing you to place realtime effects.
Further information can be found on https://support.audacityteam.org/audio-editing/using-realtime-effects
Merged the mixer bar with the meter bars.
Added a new Audio Setup button, replacing the Device Toolbar by default. The device toolbar can be re-added via the View > Toolbars menu.
The Effects menu has gotten a new sorting. Other sorting and grouping options can be found in the Effects preferences.
Updated the icons
Added a quick audio sharing feature.
More info can be found on https://support.audacityteam.org/basics/sharing-audio-online
VST3 effects are now supported.
VST3, LV2, Audio Units and LADSPA are now realtime capable
Plugins now automatically get scanned, tested and enabled when Audacity starts.
You can find plugins on https://plugins.audacityteam.org
Apple Silicon (arm64) is now supported on macOS.
Note: When using an arm64 Audacity, you must use arm64 FFMPEG and plugins. Plugins for x86-64 (Intel macs) will not load.For the time being, Audacity will continue to offer x86-64 versions by default to avoid these incompatibilities, but you can download an arm64 version from Github releases.
FFMPEG 5.0 (avformat 59) is now supported, in addition to avformat 55, 57 and 58
Added support for Wavpack
On Linux, Audacity can now be compiled without JACK present.
Audacity now uses XDG directories on Linux. Note: If you are upgrading from a previous version, Audacity will keep using the ~/.audacity-data and ~/.audacity folders until you delete them.
Switched from mad to mpg123 as MP3 importer
Audacity has been added to the Windows Package manager (winget).
Audacity binaries are now licensed under the GNU General Public License, Version 3. Most code files remain GPLv2-or-later, but VST3 support required this license update. More information can be found in the announcement post.
Removed the Zoom Tool
The Audacity Manual HTML pages no longer are included in the installation.
If you require offline access of the manual, you can download it here.You also can download PDFs of https://support.audacityteam.org straight from its sidebar (or the three-dot button in the top-right corner on smaller/mobile devices).
3079 Fixed Audacity sometimes not being able to import MP3 files (or reporting Huffman Data Overruns) by switching import library
2590 Fixed rare data loss bug when placing labels during recording
2272 Fixed clip titles being able to disappear off-screen when editing them
2162 Fixed Punch and Roll not paying tracks in sync
1889 Fixed clip titles changing name when applying some effects
1624 During batch processing, Audacity will no longer stop to ask for a sample rate when an unsupported one is chosen, but choose the nearest supported one instead.
2265 Fixed mod-script-pipe not being installed on Linux
3571 Fixed GTK packaging in Appimages. This fixes various issues with icons, dropdowns and similar things not appearing properly.
3634 Improved M4A/AAC support. Previously the target bitrate was not honored at all, now it can be set between 98 and 160 kbit/s (mono) or 196 and 320 kbit/s (stereo). The UI does not yet reflect these limits.
A full list of changes can be found on Github.
Windows
Audacity 3.2 supports Windows 10 & 11
Windows Vista, 7 and 8.1 should still work, but are no longer tested.
Downloads for older versions are available on the Legacy Windows page on the Audacity Website.
macOS / Mac OS X
Audacity 3.2 supports OS X 10.9 and later, and macOS.
There are legacy versions for older OS X at http://audacityteam.org/download/legacy-mac/.
Linux
In addition to the traditional update path via package managers, Audacity 3.0.3 and onwards are distributed as an AppImage. The AppImage gets updated at the same time as the Windows and macOS versions, so if you collaborate with users on those platforms, you may want to use the AppImage over your distribution's package manager.
Linux support is tested on Ubuntu 20.04.
Other Linux distributions should work, but aren't tested by the Audacity team.
This page is an overview of prominent new functionality that has been introduced in Audacity 3.0.4
Version 3.0.4 is a hotfix release.
Fixed a bug with envelope points, which could multiply uncontrollably and cause Audacity to crash. In particular:
#1476: Envelope points are multiplied when using Filter Curve EQ or Graphic EQ
#1477: Filter Curve EQ will crash if there is an envelope point outside of the selection
With the release of Audacity 3.0.0 the project file structure of Audacity was changed significantly with the entire project contained in a single unified database file.
If you have already updated to any 3.x version you should already be aware of this.
But if you are updating from any earlier 2.x Audacity version please read Updating from Audacity 2.x to Audacity 3.x.
Audacity 3.x can usually open AUP files created in older 2.x.x versions of Audacity, but saving the project in 3.x will prevent it opening again in Audacity versions prior to 3.0.0.
Note that this will leave behind the old AUP file and its associated _data folder which you will probably want to delete to recover disk space.
Audacity version 3.x should be able to open projects from Audacity 1.1 onwards - but not from 1.0
This page is an overview of prominent new functionality that has been introduced in Audacity 3.0.2
Version 3.0.2 is primarily a maintenance release.
Details of all the major changes since 3.0.0 can be found in Audacity 3.0.2.
Audacity 3.0.2 is about bugfixes for Audacity 3.0.0. Some bugs which didn't show up in our testing of 3.0.0 became apparent once 3.0.0 was being used by more users. We wanted to fix these and also to get more diagnostic information about what goes wrong when SQLite (the database we use) can't read or write a file. So we added more informative diagnostics for when there is an error.
One cluster of bugs we fixed relate to Unicode. Unicode is a system for representing many non-English letters and symbols. We, Microsoft and Apple all have made mistakes with Unicode that affected Audacity 3.0.0. One problem we tracked during 3.0.0 turned out to be a Windows update issue with Unicode input, which was resolved by a later Windows update. Disappearing checkmarks in macOS Big Sur release turned out to be a Unicode issue, believed to be in Apple code, which we now work around in 3.0.2. A mistake we made with Unicode prevented Audacity working in Korean and Japanese.
Some of our bug-fixes are small changes in areas where the previous Audacity behaviour was not as we wanted. 3.0.2 may only be a 'point' release, but we think it's one most people using 3.0.0 will want.
After 3.0.0 was launched a few users discovered a couple of mysterious bugs which we had not encountered in our extensive QA testing of alpha and Release Candidate builds. These two important bugs that 3.0.0 users saw were hard for us to track down as we could not replicate them. We added extra diagnostic information to help us do that:
Error: Failed to open database file
There was an error which only occurred occasionally for a few users but had us mystified. Usually this seemed to occur when trying to import an audio file, but there may have been other ways it could happen. It did not appear to be causing users to experience data loss or damaged projects. It was this bug: Bug 2700 - "Failed to open the project database"
We added a Show Log to this error message so we could gather more information about this to aid the developers in analyzing the issue. This led to what's probably a solution, as Jack L, with this extra logging, was able to get the problem sufficiently often for us to get a handle on it. This extra information told us that in some circumstances we were trying to access the disk before it was ready again, with back to back requests too quickly. Paul then changed the logic of opening a database so that two important requests were always one after the after. This should address the opening issue. Leland added a retry, so that if SQLite can't yet read the database, it tries again, but fractionally later. The retry timeout should benefit all code in Audacity that reads the database, not just at the time of opening. Jack L then ran his torture tests workload and the problem he experienced was gone.
Even so, because the original error was only occasional, we can't know for sure that it, or similar issues, are gone! We still have the extra logging in Audacity. If you do encounter the dialog indicating a problem, please click on the Show Log chevron to generate the log and send us a copy of the screenshot to the Audacity Forum. You may see a variant of the message, "The project's database failed to reopen"
This can normally be resolved by simply exiting Audacity, relaunching and then making the required import of an audio file.
False recovery offered on launch
This is another mysterious issue which only occurred very occasionally and was foxing us.
Sometimes after exiting Audacity without saving the project when offered, on the next relaunch a false recovery can be offered when there is really nothing to be recovered as no crash has occurred to cause this. We think this error had the same underlying cause, but we don't know for sure.
This bug is Bug 2732 Faux recovery offered on launch (very moonphase). If you encounter this and accept this recovery it "recovers" an empty project and no damage is done.
If you do see this error, please let us know what you can of how it happened.
With the release of Audacity 3.0.0 the project file structure of Audacity was changed significantly with the entire project contained in a single unified database file.
If you have already updated to 3.0.0 you should already be aware of this.
But if you are updating from any earlier 2.x Audacity version please read Updating from Audacity 2.x to Audacity 3.x.
The Manage Macros dialog has been improved for this release:
The Cancel button has been removed
It is replaced with a Close button
A new Save button has been added to enable you to save the results of editing a Macro.
The Save button is grayed-out until you edit a Macro.
We have extended the options in Directories Preferences to include a new entry for Macro output.
If you leave the entry for Macro output blank then Audacity will default to creating a folder called "macro-output" in:
Windows: C:\Users\<your username>\Documents\Audacity
Mac: /Users/<your username>/Documents
Note carefully that this diverges from previous behavior with 3.0.0 and earlier where a "macro-output" directory was created/used in the same directory as the files to be processed by the Macro.
We believe that a single rationalized folder for all Macro output from processing files with Macros is a more sensible approach.

This page is an overview of prominent new functionality that has been introduced in Audacity 3.0.0
Version 3.0.0 is primarily a release for a unitary, single self-contained, project file.
Details of all the major changes since 2.4.2 can be found in .
Audacity 3.0.0 introduces the new AUP3 project format. Project files saved with this version will have an aup3 extension, for example My-Project.aup3. We believe that this new project format will make life easier for Audacity users, as it replaces the previous project storage format - which used an AUP file and its associated _data folder full of little audio clips - with a single project file that integrates those two parts.
The old structure caused too many users to lose or damage their projects by moving or deleting the project components. The new single project file structure precludes that happening.
AUP projects from previous versions of Audacity can be opened or imported in Audacity 3.0.0 (Audacity converts them to the new unified file format).
Note that saving as AUP3 will leave behind the old AUP file and its associated _data folder which you will probably want to delete to recover disk space.
Once you have saved the project in the new AUP3 format they can then no longer be opened in previous versions of Audacity.
The workaround is to Export as WAV files, exporting individual tracks using and then Importing those into older Audacity versions.
Active projects cannot be saved to a FAT/FAT32 formatted drive as FAT is subject to a maximum file size of 4GB which can easily be temporarily exceeded when editing.
Saved Projects with the new unified file structure should not be larger than similar projects with the old multiple files structure.
As you work on a project, Audacity will consume additional temporary disk space. This is normally released on closing the project. This is not new with Unitary Project File, previous versions of Audacity also used to do this.
You can, if you wish, compress your project removing the temporary storage with:
File > Save Project
File > Exit
Relaunch Audacity
File > Open...
But note carefully that this will remove your Undo History and the contents of your Audacity clipboard.
Extensive speed testing has shown that for most work in Audacity the new project file can be a little faster than the old project structure.
This is especially true of using the Effects and Generators which run faster with the new project file.
Closing a project can now take a little longer as Audacity clears up the unused temporary disk space in the file.
You will get a progress dialog informing you about the Compaction progress.
Automatic Recovery (following a crash) is different in Audacity 3.0.0. It is simpler with no orphan block-files or missing block-files to worry about
When Audacity is launched following a crash it will offer to recover the crashed projects.
You can choose to either accept the recovery or to discard the projects.
You can select projects for either action by clicking on their checkbox, or you can select all by clicking on Select.
You can discard just some and then the recovery dialog will remain open enabling you to select others for recovery.
In addition to the single database project file the database also creates two temporary work files WAL & SHM files. For example My-Project.aup3-wal and My-Project.aup3-shm. On Mac there is only the WAL file.
These are deleted on closure of the project or on exit from Audacity.
Do not delete them or move these temporary files while the project is open as this will destroy the project.
Windows blocks you from doing this but macOS and Linux do not.
There is a new backup command for projects: File > Save Project > Backup Project.
This saves a copy of the current project as an AUP3 file, but with a new name. It is the safe and recommended way to make a safety backup copy of a project as you work on it.
This could serve either as a single backup copy of the project, or as one of several incremental copies of the project in the state it had at a particular date and time.
Unlike "Save Project As..." using this command will leave your current project open enabling you to continue working on it.
You are strongly advised to make backup versions of your project at key stages in your project so you can return to that stage if you mess up.
This new command replaces the two previous commands:
File > Save Project > Save Lossless Copy of Project
File > Save Project > Save Compressed Copy of Project
You can losslessly compress an AUP3 project with standard utilities such as ZIP, WinZip or 7-Zip.
Corsican language has been added for 3.0.0, thanks to Patriccollu.
Marathi language has been added for 3.0.0, thanks to Mukul Kulkarni.
Thanks also to all our regular translators who brought translations up to date for 3.0.0.
A new analyzer has been introduced called Label Sounds. It supersedes and replaces the old Sound Finder and Silence Finder analyzers.
Label Sounds is a tool which can useful to label the different songs or sections (or silences) in a long recording, such as the tracks from an LP or cassette.
This analyzer is an upgrade of the old Sound Finder from previous versions of Audacity. It is more accurate, and more versatile than previous versions, supporting both region labels and point labels.
Accessed by: Analyze > Label Sounds...
It detects the audio level in the selected track(s). When the track level exceeds a specified threshold level, the audio is considered to be "sound", and when below the level it is considered to be "silence".
There are options to add point labels before or after each detected sound, region labels around each sound, or region labels between each sound (effectively labeling the silences).
You can still continue to use this Sound Finder if it is present in your Audacity app as a result of an earlier Audacity version download.
Default folder locations have been added enabling you to specify the folders to be used for each of the Audacity actions: Open, Save, Import and Export.
If you set a default folder for any of those actions Audacity will always offer that folder location when you invoke that action.
If a particular action's default folder is left blank (default setting) then Audacity will offer the last-used location for that action.
The default setting is for all to be blank.
See Directories Preferences for more details.
Import and Export of Macros has been added to the Manage Macros dialog.
Only one Macro can be imported or exported at a time.
Comments can now be added to Macros to enable you to document what is happening in the Macro.
There is a new command "Comment" in the Macro command set. Editing its parameters enables you to type the text of your comment.
The Noise Gate effect has been improved for version 3.0.0 of Audacity. It now supports faster Attack times (down to 1ms), and provides separate controls for Attack, Hold and Decay. The effect can also process much longer selections in one pass (up to 13.5 hours at a sample rate of 44,100 Hz.)
In Tracks preferences you can now set Multi-view as your preferred user-default view for tracks.
We realized that we had a couple of settings in Tracks Behaviors Preferences that affect the operation of the Cut, Paste, and Delete editing commands in perhaps unexpected ways:
Editing a clip can move other clips
Enable Cut lines
We have changed Mixer Board so that its window always remains on top when it is in use.
Many users have requested this and the original developer always wanted to do this but could not at the time because of issues with the libraries used for this feature.
These libraries have been updated by the provider and we can now make Mixer Board a top window on all three platforms.
A Repeat last used command has been added for Generators, Analyzers and Tools. These are not in the menus but are "ghost" commands that you can assign custom shortcuts to.
This enables you to simply repeat the last generator, analyzer or tool that you used, with the last settings that you used.
By default, Macro' commands cannot be applied either from a main menu or from a shortcut. They are not "Tool menu" items, and they do not respond to Repeat Last Tool.
However, if a Macro has a shortcut, then it becomes listed in and it will now respond to "Repeat Last Tool", but only if it has been launched via the shortcut. The macro is still not a "Tool menu item", even though the shortcut effectively is.
Nyquist has been updated to the latest Nyquist Version 3.16
This has enabled us to clear a lot of long-standing Nyquist-related Audacity bugs.
A large number of bugs were fixed for this release.
Here is a small selection of some of the most important.
The click removal effect can automatically remove clicks across an entire track.
To use it:
Select the audio you want to remove the clicks from. Tip:
Go to Effect > Click Removal
Set the threshold and max spike width. The default should work in most cases. You can preview the effect to get a feel of how it'll affect the track.
Click OK to apply the effect.
Caution:
The Click Removal effect requires a somewhat large audio selection (4096 samples) to function. It may not work when selecting single clicks.
The Repair effect can be used to repair short clicks. To use it:
Select a short (max 128 samples) part of audio. Tip: You can set the selection clocks in the bottom toolbar to display start and length of the selection, and change the clocks to display samples rather than milliseconds.
Go to Effect > Repair.
Audacity has several methods available to change speed and tempo of audio.
Caution: Changing speed without affecting the pitch always leads to artefacts. Avoid repeatedly applying these effects.
To change the speed while preserving the pitch, select the audio you want to apply the effect on and go to Effect > Change Tempo
Drag the slider or enter some numbers to change how much you want to speed up or slow down your audio. The controls are linked, so you just need to change the value you care about, the rest will update accordingly.
For extreme slowdowns (10x slower to thousands of times slower), you may want to use Effect > Paulstretch instead.
Note: Paulstretch is only capable of slowing down, so the stretch factor relates to how many times you want to slow down your audio.
The time resolution decides on whether the algorithm will focus on frequencies and pitch at the expense of rhythm (high time resolution), or whether it will focus on rhythm at the expense of pitch (low time resolution). Generally. 0.25 is a good compromise for most music
To change speed and pitch at the same time, use Effect > Change Speed.
You can change the speed of an entire project over time using Time Tracks. To add one, go to Tracks > Add New > Time Track. You only can have one time track per project.
Then click on the blue line and drag it upwards or downwards to change the speed at that time. Every time you click, a new control point is added, allowing you to change the speed over time
Tip: By default, the range goes from 90% to 110% speed. If you want to extend that, right-click the vertical scale (going from 90-110) and select Range... to set a new range. The new range may be between 10% and 1000%.
To use it, drag the slider to the desired speed (between 0.01x and 3x) and then click the small play button next to it to playback your audio at that speed. You can use the normal stop and pause controls to stop/pause playback.
Audacity helps you to split a long recording into separate songs for export as one audio file per song. You can for example record an audio CD or LP and then export each song into a separate file.
Use the Selection tool to remove unnecessary audio (mostly silence) from the start of the recording.
Click the Skip to Start button
Zoom in until you can see from the start of the track to the start of the music
Click and drag from the start of the music to the start of the track
Click on Edit >
Similarly, remove unwanted audio from the end of the recording and from the middle (between sides 1 and 2 of the LP or cassette).
Later in this tutorial we mention that you can use the Analyze > Label Sounds... command to identify spaces between the songs, so when you are editing the transition between side 1 and side 2 be sure to leave 2 or 3 seconds of silence, similar to what you would find between songs.
Save your work! Click on File > Save Project > .
Mark the start of the first song
Click the Skip to Start button
Click on Edit > Labels > , or use shortcut Ctrl + B.
A new label is created in a new underneath the audio track. The contents of the label are selected and ready for editing. If you need to play the track to decide where to place the split points, you can use Add Label at Playback Position instead (directly underneath , or use shortcut Ctrl + M (on Mac it is ⌘ + .).
Type the title of the first song
Mark the rest of the songs
Using the Selection tool, click near the beginning of the second song
Click as closely as possible to the start of the song
Type the name of the song into the label
Continue in this manner adding a label to mark the start of each song
This tool depends on correctly detecting the "silences" between tracks and this depends on setting their parameters appropriately for your track.
If you did the original recording properly and avoided clipping, the recording is probably not at the maximum possible volume. In order for the LP or CD to be burned at maximum volume and thus match other LPs or CDs in your collection we need to fix this.
The default choice in this dialog is to amplify to a maximum of -1.0 dB. The maximum setting is 0 dB, but the default setting of -1.0 dB provides a little headroom as some players can have playback problems with audio at 0 dB.
Some consumer-level turntables, tape decks and/or amplifiers may well record stereo channels with a stronger signal in one channel than the other, which you will probably want to correct. In that case, check the box that says Normalize stereo channels independently.
The final step involves creating multiple audio files from the Audacity project.
Click the Choose... button and pick the place where your exported tracks will be saved.
Choose the export Format from the drop-down menu:
Under Split Files Based On:
Under Name Files:
Click the Export button.
Click the OK button in the Metadata Editor (not the Save button).
Metadata Editor will appear for the next and the subsequent songs; as before, enter any additional information and click "OK" for each window. When you click "OK" on the window for the last song, all the files will export.
Backup your exported WAV or MP3 files - you do not want to lose all that valuable work and have to do it all over again. Computer hard drives can fail, destroying all data.
Ideally use a dedicated drive (1+ TB external magnetic drives are convenient and economical), or upload to an online (cloud) storage service to store the WAVs or MP3s. Better still is to make two copies on different external devices and even better is to hold an online backup as well as the local copies.
You may want to create a taxonomic file structure - for example each album can be stored in its own folder (named for the album) within a folder named for the artist (or, perhaps, composer for classical music) to make searching and retrieval easier.
You can choose various combinations of these. However, there are probably too many minor bugs and too much detail on that for most users.

If you have rapid soft clicks (such as the crackling of Vinyl), using may work better.
In most cases, having brief amounts of silence is preferable to loud clicks, so completely muting clicks is a valid strategy if other methods fail. For this, simply select the click and press the Silence button (Shortcut: Ctrl+L
/ Cmd+L
).
Unlike , the Change Speed effect keeps the waveform mostly intact, so you can use this method repeatedly without any major loss in quality.
If you want to preview your audio at a faster or slower rate than normal, but without affecting the final product, you can use the Play-at-Speed toolbar
Repeatedly click the Zoom In button until you can see just the first few seconds of the song
Click on Edit > Labels > , or use shortcut Ctrl + B
Repeatedly click the Zoom Out button until you can see the start of the third song
You can save time by using Analyze > to automatically label the regions to be exported for the songs. This method thus lets you exclude some or all of the areas between songs.
Click on Select > , or use shortcut Ctrl + A
Click on Effect >
One problem when copying records is that a loud click in one channel can cause Normalize to create an unwanted change in the stereo balance. In that case you should consider removing the click before the Normalize step, using .

Bug tracker and code can be found on Github
If you see an error when importing an MP3 file, it can have the following causes:
Your file isn't using the MP3 codec, but instead is using a codec associated with another file extension (for example, the Advanced Audio Codec (aac) usually is found in .m4a files, and PCM Wave is usually found in .wav files). A true MP3 file will show MPEG Audio, Version 1, Layer 3
.
To solve this error, you can use MediaInfo to find out what the actual codec used in the file, and change the file extension accordingly (for example rename the audio.mp3
file to audio.m4a
).
Your file is partially broken (Huffman Data Overrun). This is a bug with Audacity versions 3.1.3 and earlier, and you can fix it by installing the latest version of Audacity.
Your file is fully broken. If it can't be opened in Audacity, or anywhere else, your file might just be broken. This itself may have several reasons:
If you just recently downloaded it from the internet, you may want to try downloading it again - in case there was a transmission error.
If you just created it yourself, it might be that there was a write error. If possible try saving the file again, re-installing the app that was used to create it, or using a different app to create it.
If you had the file on your computer for a long time and it worked in the past, it might be that your hard drive is starting to fail.
There can be several reasons for this. Some things to try:
If using a wired headphone, make sure that the wire is plugged in and that the plug is clean.
Make sure that the headphones are selected in the Audio Settings output. Note: On some devices, the internal card - usually called something among the lines of "HD Audio" are handling both internal speakers and headphones, depending on which is plugged in. You may need to select this option anyway even if it says "Speaker" instead of "Headphones"
If you connected the headphones after starting Audacity, you may need to go to Transport -> Rescan Audio Devices to make them show up in the Audio Setup list.

Most microphones are mono microphones, so they by default record on the left channel only. To hear your audio on both channels, make sure you record in mono.
If you connect an external audio device (such as a USB microphone or USB headset) to your computer while Audacity is already running, it won't be detected automatically by Audacity.
To solve this, make sure the device is detected by the operating system, then select Transport > Rescan Audio Devices from the Audacity Menu Bar. The new device should appear as an option on the Recording or Playback device selection dropdown in the Device toolbar.
Enable the Software Playthrough option to listen what is being recorded. You will hear the audio through the selected playback device.
You can turn Software Playthrough on and off in the Transport > Transport Options menu.
Note: you will hear what you are recording a noticeable time afterwards. This delay is called latency. You can somewhat reduce this latency as described in Latency Compensation but it cannot be fully removed if you're using Software Playthrough - you will need an audio interface with realtime monitoring capabilities to completely remove latency when monitoring a recording.
If you want to listen to the input when not recording it first enable Software Playthrough and then click in the Recording Meter Toolbar to turn on monitoring.
Software Playthrough can also be enabled In the Recording section of the Preferences window. Check the Software playthrough of input box and click OK.
Using Software Playthrough when recording desktop audio is not recommended.
Software playthrough usually causes a delay (latency) of the live recording input due to the time it takes to reach your headphones. To prevent this, turn software playthrough off. This can be done by choosing Transport > Transport Options > Software Playthrough (on/off) and clicking it to remove the check (tick) mark.
To listen to the live recording input without playthrough latency requires hardware monitoring - that is; the input signal must be routed directly through the audio device from the input to the output rather than being passed through software from input to output.
Enabling hardware monitoring is not possible with all audio devices. In particular it can only be achieved when the same device is used for input and output. For example, monitoring a USB microphone through headphones that are plugged into a different audio device will always have latency. If hardware playthrough is not available with your hardware it may be necessary to listen to the audio source directly (acoustically) rather than through the computer.
For some typical examples of how to set up equipment to record without playthrough latency, see this Tutorial about Recording overdubs.
If you hear crackles, pops, or distortion when the recording is loud, or if the waveform is clearly touching the top and bottom edges of the track, you probably have clipping, which means that the signal has exceeded the maximum allowed level.
Try lowering the recording level using the Audacity Mixer Toolbar or the slider in the operating system. You can also check to see if you can lower the volume on the input source itself (such as the tape deck, record player or microphone). Many sound cards and USB turntables or USB tape decks have an independent volume control for the playback signal level. See Recording with USB turntables or USB cassette decks for more help with USB turntables or tape decks.
When recording, try to aim for a maximum peak of around –6 dB in the Recording Meter so as to prevent the meter's red clipping warning coming on. If the meters are set to linear, the equivalent level to aim for is 0.5. Clicking and dragging on the meter's right edge lets you expand the meter to gauge levels more easily. After recording, you can boost the level safely using the Amplify or Normalize effects.
Help with repairing clipped recordings: If there is only a small amount of clipping (just the tops of a few isolated peaks), Effect > Clip Fix can be applied to just the clipped sections. This will attempt to reconstruct the missing peaks by interpolating the lost signal. In other cases where there is mild distortion throughout a recording, using Effect > Filter Curve EQ or Effect > Graphic EQ to reduce the higher frequencies can help to mitigate the damage. Sometimes a bass cut will help also by making the result sound less "muddy".
This is a visual indication that your recording has clipping. See the immediately previous question above.
The vertical red lines show where the clipping has occurred; these clipping indicators can be turned on and off (Audacity default setting is "off") by selecting View > Show Clipping (on/off).
The recording slider in Mixer Toolbar is purposely disabled if it cannot directly manipulate the operating system's slider for the sound device, or if that device has no system slider. Turning down the Audacity slider to prevent distortion would be inadequate unless it also turned down the system slider. It would only make existing distortion quieter instead of removing it.
If the slider is disabled, check first in Device Toolbar that you are selecting the correct device. Audacity should be able to control the recording level of most built-in sound devices subject to the device having appropriate Sound Device Drivers.
If necessary look in the operating system mixer or in the audio interface's control panel for an input slider. For Windows see Windows: accessing the Windows Sound controls. To locate the system mixer for Mac and Linux see the help on our Wiki for Mac or Linux.
External recording devices such as USB turntables or tapedecks or interfaces may not have an operating system slider, especially on Mac. For all cases where there is no system slider, try to adjust the playback level on the recording device itself.
This page lists Audacity error codes and provides some troubleshooting steps on how to fix them.
This error indicates a problem with the hardware used for playback, whether it is permissions, drivers, connections, or if you ask the device to do something it cannot do. You can attempt the following steps to resolve it.
This error indicates a problem with the hardware used for recording, whether it is permissions, drivers, connections, or if you ask the device to do something it cannot do. You can attempt the following steps to resolve it.
These errors can occur when attempting to load a damaged .aup3 project file. Damaged project files can be recovered as described in the following article.
This error indicates that the device that's being attempted to use is not valid, for example:
The device got unplugged
The device has a faulty or loose connection
The device itself is faulty or not a real audio device.
This error can also occur when you are trying to record a number of channels that is not supported in the current configuration
This error can also occur when using Audacity on Windows with Windows WASAPI as the Host if the selected recording device is being used exclusively by another application. Some applications that could make use of the recording device exclusively are ASIO4ALL, Voicemod (when configured to do so) or Voicemeeter (when configured to do so).
You can attempt to fix this issue with the following methods:
Use a different USB port and USB cable. This will resolve the issue if the fault was in the cable.
Use a different audio host. Sometimes WASAPI works when MME doesn't, sometimes it's the other way round.
Use a different number of channels. For example, some Realtek only work when recording in Mono, while some others only work in Stereo when recording a (loopback) stream.
This error can indicate an unsupported sample rate. Double-check that both your OS settings and the Audacity project rate are set to a supported sample rate (usually 44100 Hz or 48000 Hz).
This error can also occur when using Audacity on Windows to record a track while listening another existing track (also known as overdubbing) with Windows WASAPI as the Host if the sample rate of the recording device is different than the sample rate of the playback device. If possible set the same sample rate for your devices or use MME as the Host.
This error can also occur when you are trying to record a number of channels that is not supported in the current configuration To fix this, you can do the following:
Use a different audio host. Sometimes WASAPI works when MME doesn't, sometimes it's the other way round.
Use a different number of channels. For example, some Realtek only work when recording in Mono, while some others only work in Stereo when recording a (loopback) stream.
This error means "something is wrong", most commonly
A lost connection to a USB audio device
Missing microphone permissions from the operating system.
Your device is unable to playback other tracks while recording. Turning off Overdub via Transport -> Transport Options may fix this.
You can try the Common troubleshooting steps, or attempt any of the other workarounds of this page.
This error occurs when the file you're trying to open has no decoder available. You can attempt the following things to fix it:
Install FFMPEG. FFMPEG allows you to open most kinds of media files. Read more: Installing FFmpeg
Check if the file you're trying to open actually is what it says on the tin. For example, some lower-quality programs name any audio file *.mp3
, regardless of whether it actually is an MP3 file. Read more: #cant-open-an-mp3-file
Check if your file is an actual audio file. Some files which are used to output audio in certain programs don't actually contain sound themselves, but are instructions for for the program to make some sounds. Try to see if the program used to create the file has an export button. If not, you can also try recording desktop audio while playing back the file in another program. Read more: Recording desktop audio
Check if you have accidentally created custom import rules. In Edit -> Preferences -> Extended Import (on macOS: Audacity -> Preferences -> Extended Import), make sure that you have not created any custom rules. If there are any rules, you can safely delete the rules.
Import the audio as RAW. This only works on uncompressed audio. You can do so via File -> Import -> Import raw data...
This is caused by a corrupted audacity.cfg file, such as when upgrading from Audacity 3.1.3 to Audacity 3.2. You can solve this issue by upgrading to Audacity 3.2.1.
This is caused by missing realtime effects. You can replace any missing effects from the effects sidebar.
Audacity currently looks for plugins in absolute paths. This means that if you open a project that was created on a different computer, Audacity will continue to check for the plugins in the exact same locations as they were on the old computer.
If you are on a low-end machine, this may be caused by insufficient resources, specifically memory.
This also can happen if you assign yourself a static IP in the hosts
file. If that's the case, simply commenting out the assignment may solve this.
This is caused by an unexpected system state. Rebooting the computer resolves it.
Summary (5 tasks)
This page is an overview of prominent new functionality that has been introduced in Audacity 3.0.3
Version 3.0.3 is primarily a maintenance release to fix bugs and increase the stability of the Unitary Project database structure.
Details of all the major changes since 3.0.2 can be found in Audacity 3.0.3.
For the first time, Audacity will now install as a 64-bit application on Windows devices. Due to this change, some processes and effects (e.g. certain sound generation processes & sliding stretch) will run much faster.
64-bit FFmpeg library: If you are a user of previous Audacity versions on Windows and had installed the optional FFmpeg library then you must now install the 64-bit versions of the FFmpeg library, otherwise your imports and exports that depend upon FFmpeg will no longer work. See Installing FFmpeg for Windows for installation details.
Installing the 64-bit FFmpeg library will not overwrite or delete your 32-bit FFmpeg library if you have one installed.
As Audacity is now a 64-bit application, 32-bit plug-ins will not work on Audacity 3.0.3 or later.
A new colorway has been introduced on Audacity 3.0.3 for Spectrograms.
The image below shows a sample track in Spectrogram view with a spectral selection:
If you wish to revert to the former colorway just go to and choose the Spectrograms tab and from there in the Scheme dropdown menu select Color (classic).
In addition to the Grayscale which was available as a choice for Spectrogram displays in earlier versions of Audacity there is now also an Inverse grayscale.
This too can be selected from the Scheme field in Spectrograms Preferences.
A new command has been added to the View menu, View > Track Name (on / off)
When this is enabled the audio track name is displayed superimposed translucently at top left of all audio tracks.
Note that the track name is always shown in the Track Control Panel but will be truncated if the name is too long to fit.
This has the same effect as the setting for Show track name as overlay in Tracks Preferences.
Audacity will now check for updates to see if a new update of Audacity is available. This is done on launch and then after every 12 hours while Audacity remains open.
The first time that you launch Audacity 3.0.3 you will see this dialog:
The dialog has a direct link to Application Preferences enabling you to turn update checking "off" in order to opt-out of update checking.
This is not an automatic update, update does not happen without you choosing to do so from the update checking dialog that appears when a new update is available.
This has long been one of the most-requested feature requests submitted by users to Audacity and it has finally been implemented.
You can opt-out of update checking by using a new preference in Application Preferences where you can turn this "off" or "on" at any time, the default setting is "on".
The setting you make in Application Preferences for update checking is not changed by Reset Configuration.
But if you manually reset by deleting the audacity.cfg file in your Audacity settings folder this will get reset to "on" on next launch of Audacity.
You will also get shown the update checking dialog again.
Now if and when Audacity crashes, or produces an error, there will be a dialog to enable you to optionally send error and crash reports back to the developers and Quality Assurance.
Not all error messages have the ability to automatically send back information to the developers and Quality Assurance.
We now provide an official binary for Linux in the form of an AppImage.
With the release of 3.0.3 Audacity has released the following Privacy Notice.
The Privacy Notice explains how Audacity collects and uses any information that, alone or in combination with other information, relates to you when you use the desktop application Audacity. We collect very limited Personal Data about you.
The Notice also sets out the rights that you have in relation to the Personal Data that we process about you and how you can exercise them.
In addition to the fixed bugs shown here, several changes have been made to increase the stability of the Unitary Project database structure.
P1 2754 - Change Tempo & Pitch and Sliding Stretch with selected audio in negative time crash Audacity on windows (error on Mac)
P1 2772 - Audacity crashes after failing to open corrupt project

P4 2466 - Linux: Filter Curve EQ GUI far too wide
P4 2759 - Failed Macro command leaves empty undo item in history
P4 2809 - Label Sounds fails when track sample rate is 22050 Hz
P5 1091 - Spectral Edit effects may have unpredictable results
With the release of Audacity 3.0.0 the project file structure of Audacity was changed significantly with the entire project contained in a single unified database file.
If you have already updated to 3.0.0 or 3.0.2 you should already be aware of this.
But if you are updating from any earlier 2.x Audacity version please read Updating from Audacity 2.x to Audacity 3.x.
Older Projects:
Audacity 3.x can usually open AUP files created in older 2.x.x versions of Audacity , but saving the project in 3.x will prevent it opening again in Audacity versions prior to 3.0.0.
Note that this will leave behind the old AUP file and its associated _data folder which you will probably want to delete to recover disk space.
Audacity version 3.x should be able to open projects from Audacity 1.1 onwards - but not from 1.0
