METHODS AND APPARATUS TO DETERMINE A LOCATION OF AN AUDIO SOURCE

Abstract:

Methods, apparatus, systems, and articles of manufacture to determine a physical location of an audio source are disclosed. One such apparatus includes a microphone set identifier to identify ordered microphone sets from a plurality of microphones and an estimated source location calculator to calculate estimated source locations for the audio source. The apparatus further includes an estimation error calculator to calculate respective estimation errors for corresponding ones of the estimated source locations. A likelihood calculator calculates respective likelihood values for corresponding ones of the estimated source locations and a first one of the estimated source location associated with a selected one of the likelihood values is used to represent the physical location of the audio source.
