How would I go about removing the vocals from a pre-made CD? For example, lets say I want to record my own version of stairway to heaven and just want to get rid of plant's voice. How would I do this? thanks
That said, you can try to find some plug ins called vocal removers that zero in on audio sources not panned and in the vocal frequency range but these filters will take out much of the music, altering it drastically.
The method eluded to involves inverting the phase of one of the stereo channels and then collapsing it to mono. Anything that is panned to the center, like vocals, will be phase canceled and sort of removed. Also things like bass, kick, snare, etc, will also be removed (removed isn't really what happens, more like attenuated and made to sound very strange).
