Abstract
This disclosure describes a band-limited beamforming microphone array made by the augmenting a beamforming microphone array with non-beamforming microphones. The band-limited beamforming microphone array includes a plurality of first microphones configured as a beamforming microphone array to resolve first audio input signals within a first frequency range. The band-limited array further includes one or more additional microphone configured to resolve second audio input signals within a restricted second frequency range such that the additional microphones are coupled to the beamforming microphone array. In addition, the band-limited array includes augmented beamforming that processes audio signals from the beamforming microphone array and the additional microphone(s), where the augmented beamforming combines the beamformed first audio input signal with the resolved and restricted second audio input signals to create an audio signal within a band-limited frequency range.
