ABSTRACT:
A vocal canceler receives left- and right-channel input signals, and combines their non-vocal components into a single monaural karaoke signal. It then shifts the monaural karaoke signal by one phase angle to produce a left-channel output signal, and by another phase angle to produce a right-channel output signal, providing a simulated stereo effect.
