ACOUSTIC DEVICE, VOICE REPRODUCTION METHOD, VOICE REPRODUCTION PROGRAM, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To generate a reproduction voice approximated to a real voice at a recording time of a voice content even if a plurality of channels different from a channel composition at the recording time of the voice content are composed.

SOLUTION: An extraction portion 210 extracts a voice component per voice source of a musical instrument or the like based on music information with respect to voice data recorded in a monaural form. A distribution portion 220 distributes the voice components to an L channel and an R channel based on the music information so that an audio image of the voice component extracted by the extraction portion 210 may move close to a sound image at a recording time. Then, an addition portion 230 adds a signal distributed to the L channel and adds the signal distributed to the R channel. A voice based on L channel processing data PCDLand a voice based on R channel processing data PCDRthus generated are reproduced and outputted from voice output units 130Land 130R.
