This page is an overview of the key new functionality that has been introduced in Audacity 2.3.0
Details of all the major changes since 2.2.2 can be found in Audacity 2.3.0.
We have introduced Punch and Roll Recording into Audacity as one of our most popular and long-standing feature requests.
It is Accessed by: Transport > Recording > Punch and Roll Record or more simply using its shortcut Shift + D.
This enables you to correct errors easily during the course of a recording session.
You can stop, back up over a mistake, and continue recording, resulting in one track that eliminates the errors and is properly timed, without the use of cutting, pasting, and clip-moving commands, or mixing of multiple tracks.
You can do rough editing as you go, with minimal interruption of your performance and less work left until afterwards.
This is likely to be very useful to voiceover artists and audiobook authors enabling them to make rapid corrections of fluffs as they progress.
Be aware that this is not punch-in patch repair - the repair recording carries on rolling (as the command name implies) until you specifically stop it.
We have made the pinned playhead/recordhead movable on the Timeline, enabling you to choose whereabouts on the Timeline you want it to be pinned for playback and recording
The default pinned position is the center of the Timeline as before, but you can change this by clicking on the pinned head and dragging it along the Timeline while you are playing or recording. A double-click on the head will restore it to its default position in the center of the Timeline.
You may find that a pinned Playhead/Recordhead position right of center will be more useful during recording, including Punch and Roll recording, but a position back in the middle may be more useful if you are playing, especially if you are scrubbing and seeking.
By default, scrubbing and seeking will ignore the pinned playhead (if it is turned on) and will play with an unpinned playhead. This will cause the playhead to move with the waveform remaining static.
You can change this by turning "off" the option for "Always scrub unpinned" in Playback preferences. This will cause the playhead to remain static and the waveform will move under it while scrubbing and seeking.
The un-pinned head is probably the easier way to work with scrubbing and seeking.
The Play-at-Speed Toolbar (formerly called the "Transcription Toolbar") now enables you to make dynamic changes to the playback speed as you play audio using the Transcription toolbar to set the required speed. Formerly you had to stop playback and restart it to get the changed speed.
The Play-at-Speed toolbar has also been made resizable, so you can stretch it by dragging the right end rightwards, and so get a longer slider with more precision to it. At the same time as we made this change we also made the Mixer toolbar resizable, to give more precision over the main volume and playback settings if you want it.
A collection of features added to Audacity for 2.3.0 are related. They come from a project to improve batch processing. Listed here, they are described in more detail in following sections. The project led to improved:
Macros feature (replaces Chains), for repetitive tasks that can be done without using a scripting language.
Scripting using a scripting language such as Python running outside Audacity.
The project led to the new tools menu, and the new Scriptables submenus with many new commands.
The old Chains command (for batch processing and effect automation) has been replaced by an extended command. Macros can do everything that Chains did before, however there are now many more commands it can use - including new commands that have been created specially for batch processing.
We have changed the user interface integrating the functionality so that you now can view, edit and apply your macros from the same single dialog window, simplifying the usage of macros.
Re-setting the parameters for commands in macros has been simplified. Now double clicking on a command in a displayed chain will pop up the parameter settings dialog for that command.
The dialog window can be reduced in size and scope by using the Shrink button. This reduced 'Macro Palette' dialog can apply macros to your project, but does not edit them.
Many more commands are now available to Macros. Previously the commands were mostly effects. Now nearly all menu items are included.
A new menu item Tools has been created, with customizable tools.
Chains feature renamed as 'Macros'.
Extended documentation on using Macros for presets and other tasks.
Dialogs have help buttons
Some new prebuilt macros are available in Tools, and you can configure and add your own.
Macros are bindable to key presses.
New Nyquist Prompt in Tools with enhanced capabilities.
We have created a new submenu from the File Menu called Save Project
This replaces the former Save Project and Save Project As commands and these move into the new submenu. The Save Compressed Copy of Project... is also moved to the new submenu (it was in File > Export formerly).
Most importantly we have added a new command to that menu File > Save Project > Save Lossless Copy of Project. This is the now 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 As..." using this command will leave your current project open enabling you to continue working on it.
New Extra > Scriptables I and Extra > Scriptables II submenus in the Extra menu
24 New functions in these menus
These are likely to be particularly useful to VI users.
Actions that are currently done by mouse that can now be done by keyboard.
These functions too are available from Macros.
Nyquist effects now support translation, and the ones shipped with Audacity are translated.
We added help buttons ? to the Macros full and reduced dialogs, to the Export dialogs, to some error message dialogs and to some other dialogs that did not previously have them.
Increased legibility of trackname display. the Track Name overlay now has a background.
For collapsed tracks there is now an option settable in Tracks Preferences to show the upper half of the wave display only in order to show a little more detail.
The effect that was formerly named "Sliding Time Scale / Pitch Shift" has been renamed to Sliding Stretch for this release.
This is a simple name change, no other changes have been made to the effect. The change has been made mainly to reduce verbosity in the menu along with an attempt to make the command name more meaningful.
In response to many user requests for this we have changed Audacity so that is now possible to overwrite pre-existing projects with File > Save Project or File > Save Project As....
In doing so you will get the following warning message and please note that for safety reasons this warning cannot be turned off.
There is a new option in Tracks Behaviors Preferences for: "Use dialog for the name of new label".
This is off by default, but when enabled creating a label will pop up a dialog box for you to enter the label name (rather than the default behavior of opening the new label itself for editing). When the dialog is closed, focus is returned to the track which was the focus before the dialog opened. This functionality is primarily provided to aid Visually Impaired users who use screen readers, but may be useful to normally sighted users too.
The shortcuts for clip navigation have been changed
Select > Clip Boundaries > Previous Clip is now Alt + , - was Alt + P
Select > Clip Boundaries > Next Clip is now Alt + . - was Alt + N
Windows: Queen Mary 1.7.1 Vamp plug-ins crash Audacity on opening Plug-in Manager - see bug #1244
Inconsistent behavior when recording with a selection defined see bug #1839
Ctrl + M does not open label for editing - see bug #1852
Vertical Zoom in by clicking in the vertical Scale, or context menu, in waveform views is inconsistent see bug #1810
Deletion of all tracks cannot be undone - see bug #1845
Timer Record with a selection present can get a truncated recording with data loss - see bug #1851
Duplicate shortcuts can be created - see bug #1786
Labels longer than 260 characters are now supported - see bug #1905
Using Spectrogram Settings in TCP or using Preferences causes Audacity to reset Project Rate to default rate in Quality Preferences - see bug #1977
Cut Preview should play all selected/sync-locked tracks, respecting Mute/Solo during preview - see bug #231

Known bugs on the OS you use Mac, Windows or Linux.
Known bugs to do with accessibility or localization.
Workarounds for some bugs.
Serious bugs and less serious bugs.
We do use this detail in our own QA work.
Some of the bugs we fixed for Audacity 2.3.0:
Timer record continues recording and does not stop at the stated time. You may on low powered hardware still see slow updates to the timer, and we haven't fixed that entirely yet.
QM 1.7.1 plug-in crash, now fixed.
Envelope curves got badly confused when joining clips.
"The Incredible Shrinking Toolbars" - Toolbars getting smaller if you repeatedly docked and undocked them.
Below are listed what we believe are the most common and important issues with 2.3.0 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 2.3.0 requires the CPU to support the instruction set which should be available on any Intel hardware produced after 2001 and any AMD hardware produced after 2003.
To check what SSE levels your CPU supports, you can install .
If your hardware only supports SSE, you may download Audacity 2.0.6 see the page on the Audacity Website.
There are legacy versions for older OS X at .
You can choose various combinations of these. However, there are probably too many minor bugs and too much detail on that for most users.
