Abstract:
1. A sound processing apparatus, comprising: a sound separation unit that separates an input sound into a plurality of sounds caused by a plurality of sound sources, wherein the sound separation unit separates the input sound into a plurality of sounds in units of blocks of a predetermined length and determines whether the sounds separated by the sound separation unit are identical among the plurality of blocks, the determination being based on whether the blocks originate from the same sound source; 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 automatically 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.
