Abstract:
Wind noise reduction in microphone signals. A first microphone signal is obtained from a first omnidirectional microphone and, contemporaneously, a second microphone signal is obtained from a second omnidirectional microphone. The first and second microphone signals are mixed to produce an output signal. Mixing involves weighting the first and second microphone signals by respective first and second signal weights to produce respective first and second weighted microphone signals, and summing the first and second weighted microphone signals together to produce the output signal. The first and second signal weights are calculated to minimize the power of the output signal.

Claim (Index 8):
The method of  claim 7  wherein a weighting factor a i  is calculated for each subband i, and the a i  are applied on a subband-by-subband basis to give different mixing ratios at different frequencies.
