1. An image capture device, comprising:
a processor configured to:
determine coherence values between a first microphone signal and a second microphone signal across a frequency band comprising frequency bins;
compare the coherence value of each frequency bin against an average coherence value across the frequency band;
detect an elevated coherence value in at least one frequency bin of the frequency band, wherein the elevated coherence value indicates a presence of a whistle; and
attenuate the first microphone signal over the at least one frequency bin based on a determination that the elevated coherence value is above a threshold.
