Abstract:
1. A sound processing apparatus, comprising: 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 that are different from the characteristics of the first input sound, wherein the input correction unit corrects a difference in sampling frequency between the first input sound input and the second input sound input; 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; a sound type estimation unit that estimates sound types of the plurality of sounds separated by the sound separation unit; a mixing ratio calculation unit that calculates a mixing ratio of each sound in accordance with the sound type estimated by the sound type estimation unit; and 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.
