Abstract

Audio data requires a large number of bits for representation. For example, CD quality stereo audio requires 176.4 Kbytes/sec data rate for transmission or storage. This bandwidth is too large for many applications such as voice transmission over the Internet. Even when there is no live audio transmission, the storage cost may be high. An audio CD only typically contains up to 74 minutes of audio. It has been found that if audio data is compressed carefully, excellent quality audio can be stored or transmitted at a much lower bit-rate. In this Chapter, we present the basic principles of audio compression techniques, followed by brief discussions on a few selected audio compression standards.
