Method and apparatus for separating a sound-source signal

摘要

A sound-source signal separating method including steps of enhancing a target sound-source signal in an input audio signal, the input audio signal being from a mixture of acoustic signals from a plurality of sound sources and picked up by a plurality of sound pickup devices, detecting a pitch of the target sound-source signal in the input audio signal, and separating the target sound-signal from the input audio signal based on the detected pitch and the sound-source signal enhanced in the sound-source signal enhancing step.
