Digital audio data compression
Fred Wylie · Electronics & Communications Engineering Journal · 1995
Conventional digital audio, as used for instance on compact discs, requires a large bandwidth for transmission and enormous amounts of storage space. Developments in high-speed digital signal processing chips have made it practical to reduce these requirements by employing sophisticated data compression techniques which reduce redundant and irrelevant information in the source signal. The paper reviews the types of digital audio data compression coders that are now available, their applications and the principles involved.
