Abstract
This is a brief description of audio channel or sound source separation algorithm using spatial cues. Basically inter-channel level difference (ICLD) is used for discriminating sound sources in a spatial grid for each channel pair and analysis subband. Interchannel cross-correlation (ICC) is also used for determining sound source location area and contribution factor for the considering composite sound source. In this paper, the center and side channel separation of stereophonic music signal using spatial sound source discrimination method is introduced. This is simply implemented by using given information of center channel location and derived spatial cues. The separated center channel signal is well matched with separated side channels when reproduced simultaneously.
