Patent ID: 8086334

Claim:
A digital signal processing system for creating a multiple channel time-domain output signal from a multichannel signal, the system comprising: a memory; a selection module for selecting two channels from the multichannel signal as a pair; a time-domain to frequency-domain transform that, responsive to one of the two selected channels, generates at each of a plurality of frequencies, a first vector that represents the one selected channel and responsive to the other of the two selected channels, generates at each of the plurality of frequencies, a second vector that represents the other selected channel and that stores the first vector and the second vector in the memory; a vector resolver that, at each of the plurality of frequencies retrieves a first vector and a second vector corresponding to that frequency from the memory and mathematically resolves a set consisting of that first vector and that second vector into a set of at least three derived vectors such that a vector sum of the derived vectors equals the vector sum of that first vector and that second vector; and a frequency-domain to time-domain transform that, responsive to the plurality of derived vectors generates a plurality of derived output channel time-domain signals.
