Remove audio

Can I remove from an audio file music that “covers” a conversation?
I recommend using an “adaptive” filter, is possible with Audacity?

Usually this isn’t possible unless the music and the conversation are in different parts of the stereo field …

If you have an exact copy of the music without the conversation, (i.e. if the music was a recording being played, not a live performance),
you could try spectrally subtracting it from your recording, e.g. using Kn0ck0ut (free),
although I very much doubt that this will completely remove the music , [this technique can be applied to a mono recording].
