Full details of new features in the visual guide to New features in Audacity 2.4.0

Supported Platforms


  • Audacity 2.4.0 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.

  • 2.4.0 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. Use the CMake build. The Automake build is no longer reliable.

    • Audacity may compile on Gentoo, Debian, Mint.

    • Audacity does not currently compile on SuSE Linux.

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 2.3.3 that we have fixed for 2.4.0

  • 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.

You can choose various combinations of these. However, there are probably too many minor bugs and too much detail on that dynamic buglist page 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 2.4.0 for most users.


  • 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.
