Abstract
A method of processing a series of microphone inputs of an audio conference, the method including the steps of: (a) conducting a spatial analysis and feature extraction of the audio conference based on current audio activity; (b) aggregating historical information to obtain information about the approximate relative location of recent sound objects relative to the series of microphone inputs; (c) utilizing the relative location or distance of the sound objects from the series of microphone inputs to determine if beam forming should be utilized to enhance the audio reception from recent sound objects.
