We’ve temporarily re-instated the 2.3.3 release for downloads whilst we investigate a serious bug that affects 2.4.0 on Windows Mac and Linux. The bug causes loss/corruption of audio.
Currently, we think the bug happens when you have two projects open at the same time and paste audio from one project to the other. Thanks to Jack L from FreeBSD for alerting us to the problem and giving us steps to reproduce it.
Those who have downloaded, and have been using, Audacity 2.4.0 may have encountered this bug. You may find it reassuring that Audacity is aware of the bug that caused the problems and that they are working on a solution to fix it.
In the meantime, it might be a good idea to download and re-install the Audacity 2.3.3 release. Based on Audacity’s blog post, it appears that the 2.3.3. release is functional. You might be able to go right back to that version as you wait for Audacity to fix the bug that is causing a problem in Audacity 2.4.0.
It is also a good idea to check the Audacity website from time to time and see if they have fixed the bug problem. My best guess is that information will be revealed in a future blog post.
