Audacity 3.0.4

Audacity 3.0.4 was released on 24. Aug 2021.

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 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.

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