摘要
A system and method of compressing and decompressing a digital signal using scaled quantization of variable-sized packets of difference samples. Difference samples are generated and subdivided into packets. Packet boundaries may be moved to maximize resolution. A scale value is established for each packet, and scaled samples are generated for the difference samples. Packet boundaries, scale values, and scaled samples are then output as the compressed signal. Decompression is performed by multiplying scaled samples by the appropriate scale value. The resulting set of decompressed difference samples are sequentially added to an initial sample to produce a decompressed signal.
