Zusammenfassung:PROBLEM TO BE SOLVED: To cope with even a short loop section by managing each of loop start frames and loop end frames by a one-bit flag in a sound source adopting a system of compressing and storing waveform data in the unit of a frame. SOLUTION: Values of "L flag" for respective frames are given on each axis of abscissa in Fig. When the L flag for a frame is changed from "0" to "1", a frame next to the changed frame is set as a loop start frame. When the L flag for a frame is changed from "1" to "0", the changed frame is set as a loop end frame. Thus even a loop size being one frame can be coped with as shown in Fig.(b).
