Abstract:
1. An apparatus for separating sound sources, comprising: a parameter determinator determining parameters associated with interchannel correlation for each sound source included in receiving multi-channel audio signals; a sound source value calculator using channel distribution values of the each sound source by the parameters to estimate at least one mixture model and calculating membership probabilities for each model for the each sound source from the at least one estimated mixture model; a sound source separator separating the each sound source from the multi-channel audio signals based on the membership probabilities calculated for the each model of the each sound source; a parameter acquisition unit acquiring the parameters for predetermined sound sources; a sound source value estimator estimating the channel distribution values of the each corresponding sound source by using the acquired parameters; and a sound source value reflector reflecting the estimated channel distribution values when estimating the at least one mixture model and when calculating the membership probabilities.
