I don't know if this is the right place, but I figured the Hoarder Community would have a good idea on software.

I'm looking for an app that will scan an audio library and pick out duplicates. It has to do this by some other means than a mere filename, file size or audio tags. Ideally it would use all of those criteria, and do an audio analysis. I do have all my music sorted, collated, and tagged correctly tho. Opensource would be awesome. Baring that, Free is also acceptable. LOL
