there are program that can do this. However, personally I don't have any to recommend. Why not just download some of these free audio editing software here at Cnet and try them.
DISCLAIMER: I'm not asking for a software that can separate audio tracks from videos (as I believe that is...against the rules?)
What I need is a software (preferably free) that can separate multiple tracks/sounds within a single audio file. There is a little bell melody in one of my songs that I think would be nifty for a ringtone, but it is also backed with a bunch of other sounds that I don't want, so I would need to separate the bell melody from the rest of the sounds.
