1. A method for processing a mixed acoustic signal comprised of multiple acoustic signals, the method comprising: localizing multiple time-frequency regions of a spectrogram of the mixed acoustic signal to obtain one or more acoustic properties from respective regions; providing at least one pitch estimate for at least one of the multiple acoustic signals as a function of combining the acoustic properties from multiple regions; and recovering at least one of the multiple acoustic signals as a function of the at least one pitch estimate, the recovering including demodulating individual signal contents using the at least one pitch estimate to recover information corresponding to and individual acoustic signal.
