Abstract:
An audio processing apparatus includes an audio input unit configured to input a plurality of audio signals, a reduction unit configured to reduce the amount of wind noise in the plurality of input audio signals, and a controller configured to control the reduction amount of the wind noise by the reduction unit based on a difference between an in-phase component and an antiphase component of the plurality of audio signals and control the speed of change of the reduction amount of the wind noise by the reduction unit based on a magnitude of the in-phase component of the plurality of audio signals. The audio processing apparatus reduces the adverse effects of the wind noise reduction process on the audio quality of the audio signals.

Claim (Index 3):
The audio processing apparatus according to  claim 1 ,\n wherein a plurality of stages of reduction amounts of the wind noise are set in the reduction unit in accordance with a difference between an in-phase component and an antiphase component of the plurality of audio signals, and when the reduction unit decreases the reduction amount of the wind noise, the controller changes the reduction amount of the wind noise to a target stage on a stage-by-stage basis with a first change interval corresponding to a set stage when the in-phase component of the plurality of audio signals is not larger than a threshold value, and changes the reduction amount of the wind noise to a target stage on a stage-by-stage basis with a second change interval which is shorter than the first change interval irrespective of a set stage when the in-phase component of the plurality of audio signals is larger than the threshold value.
