Supported Platforms


  • Audacity 2.4.2 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.

  • 2.4.2 does not support Windows XP.

    • You may try 2.2.2 on XP, but it is unsupported.

macOS / Mac OS X


  • Linux support is tested on Ubuntu Linux.

    • Audacity may compile on Gentoo, Debian, Mint.

    • Audacity does not currently compile on SuSE Linux.

Highlighted Issues

  • Below are listed what we believe are the most common and important issues with 2.4.2 for most users.


  • 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.


  • Audacity is only partially translated in many languages. We also have some issues, for example, with Right-To-Left Languages.
