Abstract
A sound processing apparatus is provided. The apparatus includes an input correction unit that corrects a difference between characteristics of a first input sound input from a first input apparatus and characteristics of a second input sound input from a second input apparatus. The apparatus further includes a sound separation unit that separates the first input sound corrected by the input correction unit and the second input sound into a plurality of sounds. The apparatus further includes a sound type estimation unit that estimates sound types of the plurality of sounds. The apparatus further includes a mixing ratio calculation unit that calculates a mixing ratio of each sound in accordance with the estimated sound type. The apparatus further includes a sound mixing unit that mixes the plurality of sounds separated by the sound separation unit in the mixing ratio calculated by the mixing ratio calculation unit.
