Anna:
It is quite possible that there is something wrong with those old projects that is causing the multiple-envelope bug to keep appearing, although (as far as I know) the bug was in Audacity, and should not occur when using versions of Audacity later than 3.0.4.

I'm not recommending that you use the web version of Audacity - quite the opposite.

I cannot reproduce the problem with a new project with "raw" audio using Audacity 3.2.1 on a Macbook Air running macOS 13.0.1. For example:

I have tried creating a new project file with two separate tracks of raw audio and I noticed that if I insert envelopes on the track, when I make edits elsewhere on the track (cut / paste / split / join etc), the envelopes on that track disappear. Only the envelopes on the track that I edit disappear, they remain on the other tracks.
Yes, so I am also unable to reproduce this issue on 3.2.1 with Windows when I use Generate to create two new tracks in a new project.

If you care to, please provide detailed instructions on how to reproduce the issue and/or upload your project then post or PM me a link. I'll take a look at it; however, possibly not until after Turkey Day = Thanksgiving here in the states.

Hi both,

There are no specifics as to when this happens - it just occurs randomly (it could be 3 edits in or 10 edits in). This is what makes it particularly frustrating as when I am zoomed into a particular section of the wave and making many meticulous edits, I zoom out and find multiple envelopes on the track. It means undoing all of my work.

Unfortunately I am unable to share the audio I am working on.

Do you have any other suggestions?
I have used the Nyquist prompt and whilst it works to initially resolve the issue at the time, more envelopes reoccur later. This is not a solution for me because I need to add a few envelopes and end up losing them with the Nyquist prompt

Hi Just adding an update - the envelope points that I have created disappear when I cut and paste a small bit of audio. I am cutting and pasting from two tracks simultaneously and the envelope points on both tracks didappear.
