Abstract
An audio processing system and method are described. A microphone is arranged to generate a microphone output signal responsive to an acoustic input. A speaker is arranged to generate an acoustic output responsive to a speaker input signal and to generate a speaker output signal responsive to the acoustic input. A wind noise detector is arranged to receive and process the microphone output signal and/or the speaker output signal to detect wind noise. A signal processor is arranged to receive the microphone output signal and is configured to process the speaker output signal when wind noise has been detected. The microphone output signal is modified using a result of processing the speaker output signal to reduce the amount of wind noise in a processed audio signal output by the signal processor.
