Hi -

Does anyone know of a preferrably inexpensive software that will 
allow me to take an mp3 or wav file, remove the drum tracks and then 
save it back again as a mp3 or wav? The full blown MIDI sofware 
packages out there seem like overkill given I only want to remove 
drum tracks. 
Just wondering if anyone had any good solutions?

Thanks for your time,
David
