Abstract:
A signal processing apparatus (201) according to the present embodiment is provided with: a measurement signal generation unit (211) which generates a measurement signal output from a sound source; a sound collection signal acquisition unit (212) which acquires sound collection signals collected by a plurality of microphones (2L, 2R); a sound source information acquisition unit (230) which acquires sound source information related to a horizontal direction angle of the sound source; filters (221, 222) which have passbands set on the basis of the sound source information, receive the sound collection signals and output filter passing signals; a phase difference detection unit (223) which detects a phase difference between the two sound collection signals on the basis of the filter passing signals; and a determination unit (225) which determines measurement results of the sound collection signals by comparing the phase difference with an effective range set on the basis of the sound source information.
