Abstract:
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) spatially localizing the second source relative to the first source as a function of the first and second signals;(c) generating a characteristic signal representative of the desired acoustic signal during performance of said localizing; andwherein said localizing includes delaying each of the first and second signals by a number of time intervals to provide a number of delayed first signals and a number of delayed second signals, and determining a first time increment representative of separation of the first source from the second source, the characteristic signal being a function of the first time increment.
