Abstract:
An apparatus for multichannel signal processing separates signal components from different acoustic sources by initializing a separation filter bank with beams in the estimated source directions, adapting the separation filter bank under specified constraints, and normalizing an adapted solution based on a maximum response with respect to direction. Such an apparatus may be used to separate signal components from sources that are close to one another in the far field of the microphone array.
