Abstract
A method may include forming a plurality of beams to receive and spatially filter audible sounds from a first microphone and a second microphone. The plurality of beams may include a first unidirectional beam to receive audible sounds from the first microphone and the second microphone, a second unidirectional beam to receive audible sounds from the first microphone and the second microphone, the second unidirectional beam having a spatial null in a direction different from that of the first unidirectional beam, and an omnidirectional beam to receive audible sounds from the first microphone and the second microphone. The method may also include determining a first energy of audible sounds filtered by the first unidirectional beam and a second energy of audible sounds filtered by the second unidirectional beam and, based on the first energy and the second energy, selecting one of the plurality of beams as a selected beam.
