There's a way to get rid of the vocals in Audacity which is fairly easy, I've messed around with it a bit, but it depends on the fact that the vocals were a) originally recorded in a separate track, and b) mixed into the instrumentals exactly in the middle between the left and right stereo tracks.
This works reasonably well on most tracks that are mixed that way! But the older, and less pop/electronic mainstream, the track is, the less likely it seems to work. (most obvious: if it wasn't recorded in stereo or with multitracking, that ain't gonna work, which means to start with almost nothing recorded before 1960. Of course if it wasn't recorded with multitracking there aren't going to be surviving acapellas anyway, hence my dilemma.) Most TMBG vocals seem to be slightly off-center, which means you can get rid of *most* of the vocal, but not all of it, that way. And you can't do the reverse and erase the instrumentals and only leave vocals, though it seems like you should be able to.
Is there a way to do it using only frequencies? It would be awesome if there was...
