Abstract: Sample data stored in a storage device, such as a hard disk, are sequentially read out and transferred to a buffer memory, and the sample data are read out from the buffer memory, one sample per sampling period. Sample data at addresses of the buffer memory, where sample data read out has been completed, are sequentially updated with sample data newly read out from the storage device. Jump-from address and jump-to address are set while the sample data are being read out, sample by sample, from the buffer memory. When the read address of the buffer memory reaches the set jump-from address, the read address of the buffer memory is caused to jump to the jump-to address to carry on reading out the sample data from the jump-to address onward. Such readout control for the address jump is used for reproduction of silent data and repetitive sound.
