Noise Gate Not Working? Ver 3.0.0

The Noise Gate in 3.0.0 doesn’t seem to be working. I’ve tried different settings but no go. The Preview button isn’t working either and once you apply the gate, there is no undo option listed in the Edit menu. I don’t think it’s working. Anyone else having a similar problem? I’m on MacOS 11.2.3 Big Sur.

This is a bug that was discovered shortly after Audacity 3.0.0 was released.
There’s an explanation and a workaround in this topic:

I’m currently testing a full fix for the next (Audacity 3.0.1) release which is scheduled to be a quick release.

Thank you Steve for the quick reply.

Just a quick update: The full fix that I’ve been testing tests out OK, so it is now in the code ready for the next release.

Is there already a release date for 3.0.1, which fix this issue?

Audacity skipped a version to 3.0.2. It’s available from the Audacity website: Audacity ® | Downloads
