ABSTRACT:
A data compression method and apparatus 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, utilizing processing of sound data samples to delete sound data between the attack portion and just before the loop start portion. The improved method further includes a step of digitally splicing the remaining attack and loop portions to form a spliced data sample.
