OK, somebody tell me why you can't take the output from one of those 'vocals removers' and subtract that from the original source (presumably yielding what was subtracted by the vocals remover)? I'm sure that in practice there will be some difficulty, but this sounds plausible, especially if working in the DSP world for the whole process. +----------------+ ! II CCCCCC ! Jim Cathey !
