Abstract
An audio processing apparatus includes a first microphone configured to obtain ambient sound, a second microphone configured to obtain noise from a noise source, a first conversion unit configured to perform a Fourier transform on an audio signal from the first microphone to generate a first audio signal, a second conversion unit configured to perform a Fourier transform on an audio signal from the second microphone to generate a second audio signal, a generation unit configured to generate noise data by using the second audio signal and a parameter related to the noise from the noise source, a subtraction unit configured to subtract the noise data from the first audio signal, and a third conversion unit configured to perform an inverse Fourier transform on an audio signal from the subtraction unit.
