Abstract
A microphone array includes one or more front-facing microphones disposed on a front surface of the collaboration endpoint and a plurality of secondary microphones disposed on a second surface of the collaboration endpoint. The sound signals received at each of the one or more front-facing microphones and the plurality of secondary microphones are converted into microphone signals. When the sound signals have a frequency below a threshold frequency, an output signal is generated from microphone signals generated by the one or more front-facing microphones and the plurality of secondary microphones. When the sound signals have a frequency at or above a threshold frequency, an output signal is generated from microphone signals generated by only the one or more front-facing microphones.
