Claims21
-31. (canceled)
A method, comprising:
- receiving a first microphone signal from a first microphone;
- receiving one or more accelerometer signals derived from an accelerometer proximate to the first microphone;
- detecting the presence of wind at the microphone, or determining a probability of wind at the microphone, based on the first microphone signal;
- in response to detecting the presence of wind at the first microphone or determining a probability of wind at the first microphone, determining one or more parameters of wind at the accelerometer based on the one or more accelerometer signals;
- and
- providing the one or more parameters of wind to a wind noise reduction module.
