CPC H04R 3/005 (2013.01) [H04R 2201/401 (2013.01)] | 27 Claims |
1. A beamforming system, comprising:
a first beamformer configured to generate a first beamformed signal based on first frequency band signals derived from a plurality of audio signals, wherein the first beamformer is configured to process the first frequency band signals using a first beamforming technique comprising a delay and sum beamforming technique preformed in the time domain;
a second beamformer configured to generate a second beamformed signal based on second frequency band signals derived from the plurality of audio signals, wherein the second beamformer is configured to process the second frequency band signals using a second beamforming technique, wherein the second frequency band signals comprise a first group and a second group, and wherein the second beamformer is further configured to process the first group using a superdirective beamforming technique performed in the frequency domain, and process the second group using a delay and sum beamforming technique in the frequency domain; and
an output generation unit in communication with the first and second beamformers, the output generation unit configured to generate a beamformed output signal based on the first beamformed signal and the second beamformed signal.
