VIRTUAL SOUND IMAGE CONTROLLER

摘要

PROBLEM TO BE SOLVED: To provide a virtual sound image controller that makes the moving direction of a sound image changeable during the movement and enables noise-free coefficient switching at the time of the change.

SOLUTION: The virtual sound image controller has: a gain control means 302 for generating a localized sound signal consisting of sound source signals of virtual sound images at the start point and end point of gain control by using a localized sound signal generated by a localized sound generating means 301 and by using a gain coefficient increasing or decreasing relatively to time; and mixing means 303 and 304 for mixing the sound source signals at the start point and end point generated by the gain control means 302 separately in a left channel and a right channel. Outputs of the mixing means 303 and 304 are passed through a sound signal output means 401 and outputted from speakers of the two left and right channels.
