Release Notes 2.4.0

Get Audacity App for Free

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.

Windows

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

Audacity 2.4.0 is for Intel Macs running OS X 10.7 and later and macOS including Catalina.
- There are legacy versions for older OS X at http://audacityteam.org/download/legacy-mac/.

Linux

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.
