Re: Sincere Request

Just as an aside. the "traces of them that remain": could you run that mono track through a gate, which is the opposite of a compressor to silence the remains of the audio on the track? That is what's done in drum tracks when you want to isolate for separate processing, a recorded track, usually a bass,  snare or both, from the slightly audible bleed through by other recorded drumkit components

You should be aware that Audacity is an audio-only editor. You can't use 
it to edit video. If you can extract the video soundtrack, you can edit 
and process it to your heart's content, but then you have to get it back 
into the video file. I have done that before, but I forget which tool I 
used.

Your best bet for removing the vocal from a song is by the process 
called OOPS (Out Of Phase Stereo). That involves inverting one of the 
channels then summing both channels to mono. That will have the effect 
of cancelling out anything that's in the exact center of the stereo 
image - which is usually the lead vocal, bass, bass drum, and lead/solo 
instruments. Traces of those instruments will probably remain, though.
