In an apparatus and method for isolating a multi-channel sound source, the probability of speaker presence calculated when noise of a sound source signal separated by GSS is estimated is used to calculate a gain. Thus, it is not necessary to additionally calculate the probability of speaker presence when calculating the gain, the speaker's voice signal can be easily and quickly separated from peripheral noise and reverb and distortion are minimized. As such, if several interference sound sources, each of which has directivity, and speakers are simultaneously present in a room with high reverb, a plurality of sound sources generated from several microphones can be separated from one another with low sound quality distortion, and the reverb can also be removed.
