Claim 31:
32. A method for separating sound sources at a node of a plurality of nodes on a network, the method comprising:
digitizing acoustic signals from a plurality of sources with a microphone array, wherein the microphone array comprises one or more microphones;
estimating spatial parameters of the digitized acoustic signals;
exchanging first data between the node and at least one other node of the plurality of nodes on the network;
estimating a plurality of time-varying source spectra for the plurality of sources from the digitized acoustic data as a function of the digitized acoustic signals from all microphone arrays of the plurality of nodes; and
estimating source signals for each or for a subset of the plurality of sources by filtering the digitized acoustic signals digitized at the node using the spatial parameters of the digitized acoustic signals and the plurality of time-varying source spectra.
