Abstract:
1. A method of signal processing, comprising: (a) detecting an acoustic excitation at both a first location to provide a corresponding first signal and at a second location to provide a corresponding second signal, the excitation being a composite of a desired acoustic signal from a first source and an interfering acoustic signal from a second source spaced apart from the first source; (b) determining location of the second source relative to the first source as a function of the first and second signals, which includes delaying each of the first and second signals by several time intervals to provide several delayed first signals and several delayed second signals and providing a time increment representative of separation of the first source from the second source; and (c) generating a characteristic signal representative of the desired acoustic signal during performance of said determining, the characteristic signal being a function of the time increment.
