Classification: CPC G  H | IPC G  H

Claim 0:
1. A method for separating sound sources, the method comprising:
digitizing acoustic signals from a plurality of sources with a plurality of microphone arrays,
wherein each of the plurality of microphone arrays comprises one or more microphones;

at each of the plurality of microphone arrays, sending first data to a processing node;
estimating spatial parameters of the digitized acoustic signals;
estimating a plurality of time-varying source spectra for the plurality of sources from the digitized acoustic signals as a function of the received first data; and
estimating source signals for one or more of the plurality of sources by filtering the digitized acoustic signals digitized at the microphone arrays using the spatial parameters of the digitized acoustic signals and the plurality of time-varying source spectra from all of the plurality of microphone arrays.
