Abstract
Method, apparatus, and computer-readable media to manage undesired sound sources in microphone pickup/focus zones preferably mitigates one or more of the undesired sound source(s) in a space having a plurality of microphones and at least one desired sound source. Preferably, at least one microphone input receives plural microphone input signals from the plurality of microphones in the space. Preferably, the least one processor is coupled to the at least one microphone input and receives the plural microphone input signals. Preferably, the at least one processor determines plural micro-zones in the space. Preferably, the at least one processor determines a threshold sound field level for each micro-zone based on received plural microphone input signals that correspond to the one or more undesired sound source(s). Preferably, the at least one processor recognizes a desired sound source when received plural microphone input signals exceed one or more threshold sound field level.
