Changes and improvements since previous version

Audacity 3.0.4 replaces all previous versions.

This is a hotfix release that fixes a bug with envelope points, which could multiply uncontrollably and cause Audacity to crash. In particular:

  • #1476: Envelope points are multiplied when using Filter Curve EQ or Graphic EQ
  • #1477: Filter Curve EQ will crash if there is an envelope point outside of the selection

This fix re-introduces an earlier, but way less destructive bug:

  • bugzilla 208 / #1500: Some effects delete Envelope Control Points, or do not move them when timeline changes

Other than that, this release is identical to Version 3.0.3.

Supported Platforms

Audacity is for Windows, Mac and Linux desktop machines. There is no version of Audacity for Android or iPhone.
  • Audacity 3.0.4 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.
  • 3.0.4 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 should work on other Linux distributions, but isn't tested.
