In a sound-source signal separating method, a target sound-source signal in an input audio signal is enhanced, the input audio signal being from a mixture of acoustic signals from a plurality of sound sources picked up by a plurality of sound pickup devices. The pitch of the target sound-source signal in the input audio signal is detected, and the target sound-source signal is separated from the input audio signal based on the detected pitch and the enhanced sound-source signal.
