Processing digitized microphone signal data in order to detect wind noise. A first signal and a second signal are obtained from at least one microphone. The first and second signals reflect a common acoustic input, and are either temporally distinct or spatially distinct, or both. The first signal is processed to determine a first distribution of the samples of the first signal. The second signal is processed to determine a second distribution of the samples of the second signal. A difference between the first distribution and the second distribution is calculated. If the difference exceeds a detection threshold, an indication is output that wind noise is present.
