Background-sound control apparatus, background-sound control method, readable recording medium with recording background-sound control program, and video game apparatus

摘要

A background-sound control apparatus, a background-sound control method, readable recording medium (5) containing a background-sound control program (5), and a video game apparatus improve effectiveness of background-sound data within the predetermined number of channels. When background sounds are produced through a speaker (4), sound-level control means in sound control means (81) controls output ratios for sound levels defined in background-sound data (52) on a channel basis and uses a sound-level control function (51) to perform crossfading sound-level control.
