Abstract
An audio processing method including: generating a plurality of frequency spectra by transforming a plurality of audio signals inputted to a plurality of input devices respectively, comparing an amplitude of each of frequency components of a specific frequency spectrum included in the plurality of frequency spectra with an amplitude of each of frequency components of one or a more other frequency spectra different from the specific frequency spectrum included in the plurality of frequency spectra, for each of the frequency components, extracting, from the frequency components, a frequency component in which an amplitude of the specific frequency spectrum is larger than an amplitude of the one or more other frequency spectra, and controlling an output corresponding to the plurality of audio signal inputted to each of the plurality of input devices based on a proportion of the extracted frequency component in the frequency components whose amplitudes has been compared.
