Claim 7:
8. A computer readable storage device having stored thereon instructions that when executed by one or more processors result in the following operations comprising:
generating a respective subarray data set for each microphone subarray of a 3-tuple coprime microphone array based, at least in part, on an input acoustic signal comprising at least one speech signal, the input acoustic signal captured by the 3-tuple coprime microphone array and the 3-tuple coprime microphone array comprising three microphone subarrays;
determining a point by point product of the three subarray data sets; and
determining a cube root of the point by point product to yield an acoustic signal output data, the acoustic signal output data having an output amplitude and an output phase corresponding to an input amplitude and an input phase of a selected speech signal of the at least one speech signal.
