This page is an overview of the key new functionality that has been introduced in Audacity 2.3.2

• Details of all the major changes since 2.3.1 can be found in Audacity 2.3.2.

LAME is now built-in in Audacity for Windows and Mac

The LAME library, which is needed for exporting MP3 audio files, is now built-in to Audacity on Windows and macOS as a part of the application.

With previous releases it was necessary to download and locate the LAME library as an optional extra.

If you go to Libraries Preferences you will see that the option to locate the library is no longer there and the dialog tells you what version of LAME is built-in.

Select button in Track Control Panel

There is now a Select button in the Track Control Panel.

The whole of an individual track can be selected by clicking this Select button.

Holding Ctrl (or ⌘ + A on a Mac) and clicking on the Select button toggles the selectedness of the track.

Nyquist Plug-in Installer

The new Nyquist Plug-in Installer is itself a Nyquist plug-in. It simplifies the installation of other Nyquist plug-ins. It is installed by default in Audacity and can be found in the Tools Menu. It can be accessed by: Tools > Nyquist Plug-in Installer...

This plug-in installer provides a file browser for selecting the plug-in '.NY' file (Nyquist plug-ins are plain text files that have the '.NY'), and then copies the file to the correct location.

Once the plug-in has been installed, in order to use it it must be enabled using the .

Macros - "cleaned" folder renamed to "macro-output"

The folder that is created by Audacity when running a Macro on files, or when an Export command is used in a Macro that is run on the current project, has been renamed to "macro-output" to give it a more meaningful name.

The created folder used to be called "cleaned" (which was a hangover from functionality that used to be in Audacity, bit was removed many versions ago).

mod-script-pipe provided with Audacity on Windows and Mac

The experimental mod-script-pipe is now available with Audacity for Windows and Mac. You need to enable it in Modules Preferences.

Preference for "Type to create a label"

The default setting for the "Type to create a label" in Tracks Behaviors Preferences has been changed from "on" to "off".

When enabled "on", if there is already a label track that has the yellow focus border, you do not need to use "Add Label at Selection" or its Ctrl + B shortcut to create a new label. Just type your required label text to create a new label at the position of the editing cursor or selection region.

The change was made as some users were confused by: a) shortcuts not working when the label track has focus b) labels not being created when the label track did not have focus.

This will not affect any previous setting that you have, or have made, for this Preference unless you chose to have your preferences reset as part of an upgrade installation.

Size restrictions on WAV and AIFF exports

WAV and AIFF audio files are size limited to a maximum of 4 GB. This is a general restriction and not an Audacity restriction.

In earlier versions of Audacity if you exported a WAV or AIFF file that would exceed those limits the file would be corrupted and truncated and this would happen without warning.

For 2.3.2 we have implemented an error trap to catch this and stop it happening. Now when attempting to export an oversized WAV or AIFF file Audacity will not do this and you will get the following error message:

Clicking on the ? Help button in the message will show the following table in the Manual

Aproximate maximum time durations for WAV and AIFF files

Size and Checksums

Changes and improvements since previous version

Audacity 2.3.2 replaces all previous versions.

• Audacity now includes the LAME MP3 encoder. Previously, due to now expired patents, you had to download it separately.

• There is a new Select button in the track panel to select the whole track.

• Audacity mod-script-pipe for driving Audacity from Python now comes with Audacity and it can be enabled via preferences.

• Over 20 bugs fixed since 2.3.1. The most serious bug was that Audacity 2.3.1 would crash if append-recording to a collapsed track.

Interactive Buglist Page

We probably track more bugs than you are interested in...

On the dynamic buglist page you can select to view:

• Complete list of bugs in 2.3.1 that we have fixed for 2.3.2

• Known bugs on the OS you use Mac, Windows or Linux.

• Known bugs to do with accessibility or localization.

• Workarounds for some bugs.

You can choose various combinations of these. However, there are probably too many minor bugs and too much detail on that for most users.

We do use this detail in our own QA work.

Highlighted Issues

• Below are listed what we believe are the most common and important issues with 2.3.1 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.
