Abstract
A background-sound switching method and apparatus is provided for switching of background-music data. A partitioning code represents an end position of a phrase of background sounds outputted through a speaker. A switching instruction device outputs a switching-instruction signal which causes switching from the background-sound data being outputted to a D/A converter to other background-sound data. Following output of the switching-instruction signal, a data-number controller stores in RAM a data number which defines a next background-sound data to be outputted to the D/A converter. A code detector detects the partitioning code of the background-sound data being outputted. At each time the partitioning code is detected, a switching controller determines whether or not the data number is stored in the RAM and, if the data number is stored in the RAM, the background-sound data being outputted is switched to the other background-sound data defined by the data number.
