Abstract
A method, apparatus, and manufacture of beamforming is provided. Adaptive null beamforming is performed for signals from first and second microphones of a two-microphone array. The signals from the microphones are decomposed into subbands. Beamforming weights are evaluated and adaptively updated over time based, at least in part, on the direction of arrival and distance of the target signal. The beamforming weights are applied to the subbands at each updated time interval. Each subband is then combined.
