The ISO-MPEG-Audio Layer III digital audio compression scheme is the most powerful of the three audio compression algorithms standardized in ISO-MPEG IS-11172. Even at very low bitrates Layer III provides a high sound quality. This facilitates the transmission of high quality audio via standard 64 kbit/s data channels. Apart form the sound quality in MPEG audio only Layer III offers additional features that allow very effective solutions for the synchronization of the sample clock to the transmission clock. This paper describes the basic features of Layer III as well as practical implementation.
