Claim 17:
18. A system for separating sound sources comprising:
a plurality of nodes on a network, each of the plurality of nodes comprising a microphone array and a processor configured to:
digitize acoustic signals from a plurality of sources with the microphone array;
estimate spatial parameters of the digitized acoustic signals;
transmit first data to at least one other node of the plurality of nodes;
receive second data from at least one other node of the plurality of nodes;
estimate a plurality of time-varying source spectra for one or more of the plurality of sources from the digitized acoustic signals and from the second data; and
estimate one or more source signals for one or more 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,

wherein the microphone array of each of the plurality of nodes comprises one or more microphone.
