Abstract
System and method for beamforming audio signals received from a microphone array. The method includes receiving at least one audio signal from the microphone array. The method includes determining a plurality of beams based on the at least one audio signal. The method includes receiving from a vibration microphone at least one vibration signal, and filtering the at least one vibration signal to generate at least one filtered vibration signal. The method includes filtering the plurality of beams to generate a plurality of filtered beams. The method includes determining a plurality of correlation values, each of the plurality of correlation values based on one of the plurality of filtered beams and the at least one filtered vibration signal. The method includes determining a peak correlation value based on the plurality of correlation values, and selecting one of the plurality of beams based on the peak correlation value.
