Abstract:
A background-sound control apparatus comprising:display means for displaying variations of events, the events displayed in the display means varying according to operations performed on operating means; sound-generating means for generating background sounds using a plurality of channels; background-sound-data containing means containing background-sound data including at least a first background sound for at least a first channel and a second channel, and at least a second background sound, different form the first background sound, the first background sound and the second background sound corresponding to respective ones of the events; output control means for outputting the background-sound data to the sound-generating means to generate the first and second background sounds; sound level control function means for defining a variation of output levels of the first background sound and the second background sound; and sound-level control means for, in response to the variation of events, effecting the following: first varying an output ratio of the output levels of the first channel to the second channel of the first background sound by decreasing the output level of the first channel while increasing the output level of the second channel in accordance with the output levels defined by the sound level control function means to generate the variation of the output ratio; and following the variation of the output ratio, setting the output level of the second background sound to a given level to generate the second background sound and ending generation of the first background sound.
