Abstract:
An audio processing apparatus includes a transform unit that transforms time series audio data obtained from first and second microphones into first and second frequency spectrum data; a driving noise computation processing unit that computes a subtraction amount of the driving noise for each of frequencies from the first and second frequency spectrum data obtained by the transform unit; a generating unit that, on the basis of the first and the second frequency spectrum data obtained by the transform unit and the driving noise subtraction amount obtained by the driving noise computation processing unit, generates left and right channel frequency spectrum data in which the driving noise is respectively suppressed; and an inverse transform unit that inverse-transforms the left and right channel frequency spectrum data generated by the generating unit into left and right channel time series audio data, respectively.

Claim (Index 12):
An audio processing apparatus comprising:\n a housing; a driving unit; a first microphone housed within the housing so that sound propagates through a first opening provided in a first predetermined position of the housing; a second microphone to which sound propagates through a second opening provided in a second predetermined position of the housing related to the first predetermined position and that has a smaller area than the first opening, the second microphone being housed within the housing so that a volume of a second space between the second microphone and the second opening is greater than a volume of a first space between the first microphone and the first opening; a transform unit that transforms time series audio data obtained from the first microphone into first frequency spectrum data and transforms time series audio data obtained from the second microphone into second frequency spectrum data; a calculation unit that calculates an amount of driving noise produced by the driving unit at each of frequencies from the first frequency spectrum data and the second frequency spectrum data obtained by the transform unit; a generating unit that, on the basis of the first frequency spectrum data, the second frequency spectrum data, and the amount of driving noise calculated by the calculation unit, generates left channel frequency spectrum data and right channel frequency spectrum data in which the driving noise is respectively suppressed; and an inverse transform unit that inverse-transforms the left channel frequency spectrum data and right channel frequency spectrum data generated by the generating unit into left channel time series audio data and right channel time series audio data, respectively.
