Scope: This specification specifies the technical solution for multi-channel digital audio compression coding and decoding: including code stream format (syntactic structure and semantics), decoding process and technical requirements for each decoding technology module, and provides informative information on the encoding part using this technology. Suggestions and implementation methods. The signal channel of the digital audio coding and decoding technology solution specified in this standard can maintain an accuracy of more than 24 bits (except for the accuracy that is intentionally discarded due to quantization). In addition to the common stereo, 5.1 surround sound, 6.1 surround sound and 7.1 surround sound, the supported channel settings also reserve space for future audio technology development (up to 64.3 surround sound can be supported). This standard can support standard sampling frequencies from 8kHz to 192kHz, including 44.1KHz and 48KHz. This standard has no clear limit on the encoding bit rate (code rate), which can be set according to channel bandwidth and sound quality requirements in specific applications. This standard applies to various digital audio broadcasting, digital TV sound, home theater, network streaming media and personal media players and other application fields.
