1. A method for operating a beamforming microphone array for use in a predetermined area, the method comprising:
receiving acoustic audio signals at each of a plurality of microphones, converting the same to an electrical mic audio signal, and outputting each of the plurality of electrical mic audio signals;
generating a user location data signal by a wave sensor system, and outputting the user location data signal, wherein the user location data signal includes location information of one or more people within the predetermined area;
receiving both the user location data signal and plurality of electrical mic audio signals at an adaptive beamforming circuit;
generating one or more beams by the adaptive beamforming circuit based on the user location data signal and the plurality of electrical mic audio signals wherein each of the one or more beams acquires sound from one or more specific locations in the predetermined area.
