Changes and improvements since previous version

Audacity 3.1 replaces all previous versions.

Prominent features

  • Clip Handles (replacing the Time Shift Tool)
  • Smart Clips (non-destructive resizing of clips)
  • Playback Looping

Smaller changes

  • 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.


  • 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.

Fixed Bugs

  • AppImages support localization. #1382
  • Progress bars for Nyquist generators have been made more accurate. #1856
  • 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 below the threshold. #1389

Supported Platforms

Audacity is for Windows, Mac and Linux desktop machines. There is no version of Audacity for Android or iPhone.
  • Audacity 3.1 requires the CPU to support the SSE2 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 CPU-Z.
    • If your hardware only supports SSE, you may download Audacity 2.0.6 see the Legacy Windows page on the Audacity Website.
  • 3.1 does not support Windows XP.
    • You may try 2.2.2 on XP, but it is unsupported.
macOS / Mac OS X
  • 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 Linux.
    • Other Linux distributions should work, but aren't tested by the Audacity team.
