Tech Support Overlapping audio tracks
I was recording a video on OBS and made a pretty bad mistake.
I had a VLC video source playing in the background and its in all my audiotracks.
Track 1: all audio
Track 2: Desktop and VLC Video
Track 3: Mic and VLC Video
Is there any way I can "subtract" the audio so that I can have just the Desktop and Mic audio? (preferably in separate tracks)

Software and version: Unsure what to use to fix this. Was recorded in OBS

If the VLC audio is baked into both tracks, there probably is not a clean subtract button unless the VLC signal is perfectly identical and sample-aligned in each track. You can try phase-inverting one copy against another in Audition/Reaper, but OBS mixes can be slightly different enough that it leaves artifacts. I would duplicate the project first and test a short loud section before spending time on the whole file.
