Abstract
Methods and systems for selectively switching between microphones in a plurality of microphones are disclosed, including providing a first state that corresponds to one or more microphones selected from the plurality of microphones. A subset of microphones may be selected from the plurality of microphones in response to determining an average power of an input signal for each of the plurality of microphones. A second state may be identified that includes at least one of the subset of microphones in response to evaluating the average powers of the input signals for the subset of microphones against a predetermined condition. A transition from the first state to the second state may be delayed in response to determining a transition delay time corresponding to the first state.
