Abstract: An audio processing apparatus includes an attachment unit for a lens including a noise source, a first microphone for ambient sound, a second microphone for sound occurring from the noise source, a first conversion unit for Fourier transform of an audio signal output from the first microphone to generate a first audio signal, a second conversion unit for Fourier transform of an audio signal output from the second microphone to generate a second audio signal, a generation unit which generates noise data using the second audio signal and a parameter concerned with noise of the noise source, a subtraction unit which subtracts the noise data from the first audio signal, and a third conversion unit which performs inverse Fourier transform of an audio signal output from the subtraction unit. The generation unit uses, as the parameter, a parameter associated with a type of the lens attached to the attachment unit.

Abstract: An apparatus includes a CPU and a memory storing a program that causes the apparatus to function as the following units. A first amplification unit that amplifies a the sound signal from a first microphone for acquiring an environment sound, a second amplification unit that amplifies a sound signal from a second microphone for acquiring a noise of a noise source in accordance with a amplification amount, a conversion unit that performs Fourier transform on sound signals from the first amplification unit and the second amplification unit, a reduction unit that reduces noise from first sound data using noise data. The amplification amount is set based on at least one of a level of the sound signal from the second amplification unit and a type of the noise source.
