Supported Platforms


  • Audacity 3.1.x 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.x 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.

    • Other Linux distributions should work, but aren't tested by the Audacity team.
