Abstract

A sound processing device performs obtaining a first frequency spectrum that corresponds to a first sound signal and a second frequency spectrum that corresponds to a second sound signal, calculating a level difference between a level of each of frequency components in the first frequency spectrum and a level of each of frequency components in the second frequency spectrum, calculating a spread of a distribution of the level difference during a prescribed period for each of the frequency components, and determining a gain to be multiplied to the frequency component in the first frequency spectrum and a gain to be multiplied to the frequency component in the second frequency spectrum in accordance with the spread of the distribution of the level difference.
