Q: I am looking for a free music editor where I can take itunes tracks and edit bass and treble and things like that. Is there any such software?

Q: I am currently trying to edit an mp3 music file on WavePad Sound editor. I need to know if there is any way possible to separate two sounds from the one track. By this I mean, if the track is made up of guitar and piano sounds but I only want the guitar sound how can I do this and on what software?
