Abstract
A beamforming microphone array is described herein, comprising: a plurality of microphones each of which is adapted to receive an acoustic audio signal and convert the same to a microphone (mic) audio signal; a wave sensor system adapted to determine locations of one or more people within a predetermined area about the beamforming microphone array and output the same as user location data signal; and an adaptive beamforming circuit adapted to receive the user location data signal and plurality of mic audio signals and perform adaptive beamforming on the plurality of mic audio signals that takes into account the received user location data signal to adapt a plurality of beam signals, one for each of the microphones, to acquire sound from one or more specific locations in the predetermined area; and a plurality of acoustic echo cancellation devices, one for each of the beam signal outputs from the adaptive beamforming circuit, wherein each of the plurality of acoustic echo cancellation devices is adapted to receive a respective beam signal from the adaptive beamforming circuit and perform acoustic echo cancellation on the received respective beam signal and output the echo-corrected beam signal.
