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 8):
An audio processing apparatus comprising:\n an input unit configured to input audio signals of right and left channels; a reduction unit configured to reduce wind noise of the audio signal by performing a high-pass filter process on the audio signal input by the input unit; and a controller configured to set a cutoff frequency of the high-pass filter of the reduction unit based on a difference between a signal obtained by adding the audio signal of the right channel and the audio signal of the left channel which are input by the input unit and a signal obtained by subtracting one of the audio signals of the right and left channels from the other of the audio signals and controls a speed of reduction of the cutoff frequency of the high-pass filter of the reduction unit based on a magnitude of the added signal.
