    Patent number: 5617506
    Abstract: A method and apparatus for a 2:1 compression of a digital audio signal including 1) a compression operation for compressing a sixteen bit sample of the audio signal as both an exact value and a delta value, and 2) a regeneration operation for regenerating the compressed exact and delta values once again into a sixteen bit word. The regenerated exact and delta values are then compared against the original sample. Whichever regenerated value most closely matches the original sample has its corresponding compressed value encoded onto a storage medium.
