1. An image capture device with dynamic wind noise compression tuning, the image capture device comprising:
at least two microphones;
a detector configured to detect the presence of wind noise by obtaining a measure of coherence between the at least two microphones;
a compressor configured to process audio signals from the at least two microphones; and
a configuration unit configured to adjust, for the compressor, a compression threshold based on the obtained measure of coherence by the detector,
wherein the compressor is configured to apply adjusted compression parameters to the audio signals when an audio signal for a microphone from the at least two microphones is above the adjusted compression threshold and apply default compression parameters to the audio signals when the audio signal for the microphone is below the adjusted compression threshold.
