Abstract
This disclosure describes a method to manufacture a conferencing apparatus for echo cancelation with beamforming microphone arrays. This method provides a beamforming microphone array for developing a plurality of microphone signals, where each microphone of the beamforming microphone array is configured to sense acoustic waves from a direction vector substantially different from other microphones in the beamforming microphone array. Additionally provided is a memory configured for storing computing instructions. Operably coupled is a processor that executes computing instructions to: perform a beamforming operation to combine the plurality of microphone signals to a plurality of combined signals that includes a number of signals between one and a number of signals in the plurality of microphone signals, each of the plurality of combined signals corresponding to a different fixed beam; and perform an acoustic echo cancelation operation on the plurality of combined signals to generate a plurality of combined echo-canceled signals.
