Abstract
The present invention provides a sound image position correction system that applies sound image position correction processing to a voice signal so that an optimal sound image position is obtained. There is provided a sound image position correction system which corrects the position of a sound image output from a plurality of speakers in a multichannel reproduction system having three or more channels, which includes a speaker moving section that moves the positions of the plurality of speakers provided in the multichannel reproduction system, a speaker position detection section that detects the positions of the plurality of speakers moved by the speaker moving section, and a sound image position correction section that applies sound image position correction processing to a sound signal to be supplied to the plurality of speakers based on the positions of the speakers detected by the speaker position detection section.
