Abstract:
An image capture device detects a wind whistle using two or more microphones. The image capture device includes a processor that obtains microphone signals from the two or more microphones and measures coherence values between the microphone signals across a frequency band. The frequency band includes frequency bins, and the processor measures a coherence value for each frequency bin. Based on a detection of an elevated coherence value in a frequency bin, the processor determines the presence of a whistle. The processor attenuates the frequency bin based on a determination that the elevated coherence value is above a threshold.
