ABSTRACT:
A moment at which each of a plurality of pieces of sound data is generated in response to one sounding operation is controlled, and the plurality of pieces of sound data are output to different sounding units. Consequently, differences occur among moments at which sounds are radiated by the sounding units, resulting in an occurrence of differences among lengths of time taken by the sounds to reach the ears of a listener, whereby a stereophonic sound can be produced and the listener can localize a sound image. A stereophonic sound system provided with a sound generating unit for generating sound data, a generation control unit for controlling a generation of sound data in the sound generating unit in such a manner that a plurality of pieces of sound data are generated in parallel with one another in response to a sounding operation, a generation moment control unit for controlling a moment at which each piece of the sound data generated in parallel with one another is produced, and an output unit for outputting the plurality of pieces of sound data generated by the sound generating unit under control of the generation control unit, at moments controlled by the generation moment control unit, to different sounding units.
