<p>A sound source separation apparatus includes a first sound source separation unit that performs blind source separation based on independent component analysis to separate a sound source signal from a plurality of mixed sound signals, thereby generating a first separated signal; a second sound source separation unit that performs real-time sound source separation by using a method other than the blind source separation based on independent component analysis to generate a second separated signal; and a multiplexer that selects one of the first separated signal and the second separated signal as an output signal. The first sound source separation unit continues processing regardless of the selection state of the multiplexer. When the first separated signal is selected as an output signal, the number of sequential calculations of a separating matrix performed in the first sound source separation unit is limited to a number that allows for real-time processing.</p> |
