PROBLEM TO BE SOLVED: To solve the problem that the same number of data transfer means as the number of sound channels is required for transferring sound data, and when the number of sound channels is increased, increase in the number of data transfer means is required and a hardware scale may be increased. SOLUTION: Data signals of a plurality of channels are divided into data blocks of a prescribed block size in each channel and the data blocks of respective channels are written in continuous areas in a memory so as to be continued in the order of channels to DMA-transfer the sound data of a plurality of channels collectively by one DMA transfer.
