Abstract:
1. A method comprising: receiving a first signal at a first detector and a second signal and a third signal at a second detector; determining a correlation between the second signal and the third signal received at the second detector and deriving from the correlation a plurality of wind metrics, wherein the plurality of wind metrics comprises a first wind metric, a second wind metric, and a third wind metric that characterize wind noise that is acoustic disturbance corresponding to at least one of air flow and air pressure in the second detector; determining based on the first wind metric a magnitude associated with the wind noise; determining based on the second wind metric whether to suspend an activity of a system coupled to the first detector and the second detector; determining based on the third wind metric a duration of time that the magnitude associated with the wind noise exceeds a threshold, wherein exceeding the threshold causes the system to switch from a first state to a second state; controlling a configuration of the second detector according to the plurality of wind metrics; and generating an output signal for transmission by dynamically mixing the first signal, the second signal, and the third signal according to the plurality of wind metrics.
