Abstract
A sound source separation method, applied in a sound system, is provided. The method comprises choosing a maximum sound source signal and at least a non-maximum sound source signal from a plurality of sound source signals; multiplying the at least a non-maximum sound source signal by at least a suppression value, to generate at least a suppressed sound source signal; and performing a back-end sound source extraction operation on the maximum sound source signal and the at least a suppressed sound source signal.
