Patent ID: 8924204

Claim:
An apparatus for detecting and suppressing wind noise in a primary signal received by a primary microphone, the apparatus comprising: a reference signal adjustment processor, in communication with a memory, configured to adjust a reference signal received by a reference microphone based on a difference between a parameter of the reference signal and a parameter of the primary signal to provide an adjusted reference signal, wherein the parameter of the reference signal and the parameter of the primary signal is a delay, gain, spectral shape, or background noise level, wherein the reference signal is adjusted to better match the parameter of the reference signal to the parameter of the primary signal; and a waveform substitution processor, in communication with a memory, configured to substitute at least a portion of a frame of samples of the primary signal with at least a portion of a frame of samples of the adjusted reference signal if a primary microphone wind noise detection signal indicates that wind noise is present or above a first threshold in the frame of samples of the primary signal and a reference microphone wind noise detection signal indicates the wind noise is absent or below a second threshold in the frame of samples of the adjusted reference signal.
