Also: Audacity > Edit > Preferences > Recording > Playthrough (do not select). The little Audacity recording window should be the name (or the electronic name) of the microphone. Oh, it’s probs also responsible to ask, “Are there any workarounds to try?” (Yes, I know I could apply DeNoise to the recording via the Waveform/Spectral Frequency view, but it’s not preferable just because of the ongoing flexibility of applying effects via the Multitrack view, having to Apply the effect, save it, having to go back into Waveform/Spectral Frequency view to undo, losing the ability to easily revert the effect after I’ve quit Audition, etc. Another name for that is Anything on the Computer. I haven’t yet been able to find any other reports online of the issue.

I think my final question is, “Is this an app bug, or is the problem instead maybe local/something screwed up with my computer (a 2020 MacBook Air)?” I do think there’s likely SOMETHING specific I’m doing that prompts this issue, but I haven’t been able to figure out what mechanic/action step/keystroke, etc. If you happen to have any guidance, troubleshooting, experience running into this, things to try, etc, I’d be SO appreciative it is really wrecking my ability to get anything done in Audition. I haven’t yet tried uninstalling/reinstalling Audition yet I first wanted to seek out solutions/guidance, see if others have experienced this issue, etc. Restarting my laptop doesn’t resolve the issue. Quitting and restarting Audition doesn’t resolve the issue.

It also happens to different tracks within the same project. This happens in projects VERY often it’s not tied to this specific project. I can’t tell if there’s something I’m doing that’s making DeNoise stop working. If I remove DeNoise from the Effects Rack, and add it again, it once again functions properly, but then after a short period of time, it will AGAIN stop working, as depicted in the video. I’ve applied DeNoise to a track (in Multitrack), but then after ~20 seconds of continuing work/usage, DeNoise stops working.

Audacity suddenly stops recording
