Abstract

There is provided a sound processing apparatus including a sound separation unit that separates an input sound into a plurality of sounds caused by a plurality of sound sources, 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 mixingratio calculation unit.

Description

technical field [0001] The present invention relates to a sound processing device, a sound processing method, and a program, and more particularly, to a sound processing device, a sound processing method, and a program that remix sounds separated based on input sound characteristics. Background technique [0002] Conversation voices, voices of photographed subjects, and the like are generally recorded by devices such as mobile phones and camcorders equipped with sound recording means capable of recording sounds. The sound recorded in the sound recording device has sounds originating from various sound sources including human speech and environmental noise mixed therein. If sounds from various sound sources are mixed and sounds from a desired sound source are recorded relatively lower than sounds from other sound sources, there is a problem in that it is difficult to determine the content of the desired sound. [0003] Therefore, there has been disclosed a technique of separ...
