|That can be done on the TV show CSI but I don't think it can be done in the real world. It would be good though.|
You can do that for a midi file but not a wav file. It would be too difficult to segragate the particular wave forms. Perhaps if you had the original sound recording that was on 32 tracks then you could isolate the individual instruments but everything we receive is usually in two tracks/stereo, left and right all mixed together.
