Claim:
1. A sound source separation apparatus comprising: a sound pickup unit configured to pick up sound signals of a plurality of channels; a detector configured to detect relative positions, corresponding to each of a plurality of frames, between a sound source and the sound pickup unit; a phase regulator configured to perform phase regulation of the sound signals of a first channel among the plurality of channels in each of the plurality of frames, using the relative positions corresponding to each of the plurality of frames, such that a phase difference between the sound signals of the first channel and the sound signals of a second channel among the plurality of channels is a predetermined value in each of the plurality of frames; one or more processors; a memory coupled to the one or more processors, the memory having stored thereon instructions which, when executed by the one or more processors cause the sound source separation apparatus to: a sound source separator configured to, for each of the plurality of frames, perform sound source separation for separating sound signals generated by the sound source from the sound signals by using a separation filter based on the sound source separation parameter.
