摘要: An apparatus for providing directional audio capture may include a processor and memory storing executable computer program code that cause the to at least perform operations including assigning one beam direction, among plurality of directions, in which direct directionality an output signal or more microphones. The further divide microphone signals microphones into selected frequency subbands wherein analysis performed. select set subbands. optimize assigned direction by adjusting beamformer parameter(s) based on Corresponding methods products are also provided.
