Abstract / scope
ISO/IEC 13818-7:2006 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.
ISO/IEC 13818-7:2006 also supplements information on how to utilize the bandwidth extension technology (SBR) specified in ISO/IEC14496-3 in conjunction with MPEG-2 AAC.
