DATA COMPRESSION OF SOUND DATA

摘要

A data compression method and apparatus (Fig. 14) for the compression of sound data utilized in digital sampling keyboard instruments. The present invention reduces memory requirements for sampled sounds without compromising sound quality. Samples have an attack portion and a cross/faded loop portion. Sound data between the attack portion and just before the loop start portion are deleted. The remaining attack and loop portions are spliced to form a spliced data sample (Fig. 6).
