Abstract
An audio signal processing system removes at least a portion of a noise component from a number of audio input signals generated by a number of closely proximate agents within an input signal source location. The availability of each audio input signal and the geographically proximate location of each of the agents creating an audio input signal facilitates the real-time or near real-time reduction in ambient noise level in each of the audio input signals using a Blind Sound Source Separation (BSSS) technique.
