Is there any equipment that can eliminate all vocals, kicks, spikes, clicks, snares, hiss, saxophones, drums, and leads by recognizing their waveforms rather than removing the central channel of a recording? Current "voice cancellors" work by ridding the whatever is identical in both right and left. This would not eliminate vocals if they were recorded differently in the right and left channels. I have heard of voice recognition software. Probably wouldn't help with music though.
