Abstract
An image capture device includes a processor for wind noise processing. The processor receives signals from a first microphone, a first plurality of microphones, and a second plurality of microphones. The processor may segment each signal into low frequency bins and high frequency bins. The processor may select a minimum level signal bin for each low frequency bin. For the high frequency bins, the processor may select a minimum level signal bin for a first group of microphones or a second group of microphones. The processor may generate a composite signal by combining the selected minimum level signal bins for each low frequency bin and the selected minimum level signal bins for each high frequency bin.
