We temporarily re-instated the 2.3.3 release for downloads whilst we investigated a serious bug that affects 2.4.0 on Windows Mac and Linux. The bug causes loss/corruption of audio.

The bug happens when you have two projects open at the same time and paste audio from one project into the other. Thanks to Jack L from FreeBSD for alerting us to the problem and giving us steps to reproduce it.

With that information we were able to find the root cause, make a fix and release 2.4.1.

We’re pleased to announce release of Audacity 2.4.0 which replaces all previous versions for Windows, macOS and Linux.

We’ve put a lot of time and work into it.

Catalina?

We have now caught up with Apple’s ‘notarization system’. Audacity on Mac is notarized and runs on Catalina.

Time Toolbar:

We have split the recording/playing time off from the selection toolbar and it can now be dragged to make it larger. This is particularly for people recording themselves playing a musical instrument, where they will typically be further from the screen when playing, and benefit from a larger numerical display.

The new toolbar can be ‘undocked’ from the foot of the screen, and made larger still, for more distant viewing.

Multi-views

We have added a new optional mode for viewing audio. In this new mode you can see both the waveform and a spectrogram at the same time. Previously you would switch back and forth between them if you wanted both.

You can get into this multi-view mode by clicking on the down-pointing triangle beside the track name in the panel on the left of the wave. This will drop-down a menu with options, including multi-view mode.

These screenshots of Audacity showing the time toolbar and multi-view mode were made on the windows version of Audacity, using the dark theme. Dark theme can be selected from the preferences.
