A sound source direction determining device for specifying the incoming direction of a sound based on acoustic signals through two channels obtained by two mikes disposed apart by a predetermined distance has a phase difference spectrum signal generating unit for obtaining the phase difference spectrum of the acoustic signals through the two channels, a power spectrum signal generating unit for obtaining the power spectrum of at least either one of the acoustic signals through the two channels, and a sound source direction specifying unit for obtaining the sound source direction of each sound source based on the phase difference spectrum and the power spectrum.
