BACKGROUND SOUND SWITCHER, BACKGROUND SOUND SWITCHING METHOD, READABLE RECORDING MEDIUM IN WHICH BACKGROUND SOUND SWITCHING PROGRAM IS RECORDED, AND VIDEO GAME MACHINE

摘要

PROBLEM TO BE SOLVED: To switch favorably background sound data. SOLUTION: A delimiter 53 indicates the ending position of a passage of background sound when being output from a speaker 4. A switching instruction means 72 outputs a switching instruction signal to switch background sound data being output to a D/A converter to another background sound data. A data number control means 82 stores a data number 54 specifying background sound data 52 to be output next to the D/A converter 18 to a RAM 8. A code detection means 83 detects the delimiter 53 of background sound data being output. The switching control means 84 decides if a data number 54 has been stored in the RAM 8 every time the delimiter 53 is detected, and switches the background sound data 52 being output to another background sound data 52 specified by this data number 54 if the data number has been stored.
