ISO/IEC 13818-7:2004 specifies MPEG-2 Advanced Audio Coding (AAC), a multi-channel audio coding standard that delivers higher quality than is achievable when requiring MPEG-1 backwards compatibility. It provides ITU-R "indistinguishable" quality at a data rate of 320 kbit/s for five full-bandwidth channel audio signals.
In comparison to ISO/IEC 13818-7:2003, ISO/IEC 13818-7:2004 supplements information on how to transmit and obtain MPEG-4 SBR data as part of the MPEG-2 AAC access unit.
