"Kn0ck0ut can also extract 'centre-panned' material from a stereo track. On many early (<1970) stereo releases, and much more rarely on recordings made since then, the vocal is the only part placed in the centre of the stereo field. If (and only if) this is the case, kn0ck0ut's extract centre feature will return only the vocal as a mono audio stream."
