Full title and description

St ISO IEC 13818-7:2006 Cor 2:2010 — Information technology — Generic coding of moving pictures and associated audio information — Part 7: Advanced Audio Coding (AAC). This entry refers to the 2006 fourth edition of ISO/IEC 13818-7 (MPEG-2 AAC) together with Technical Corrigendum 2 published in 2010, which corrects and clarifies limited technical text in the 2006 edition.

Abstract

ISO/IEC 13818-7:2006 specifies the MPEG-2 Advanced Audio Coding (AAC) format: a high-efficiency, multi-channel audio coding system intended to provide improved audio quality compared with earlier MPEG-1 audio while supporting extensions such as Spectral Band Replication (SBR) and transport of MPEG Surround. Corrigendum 2 (2010) makes editorial and technical corrections to parts of the 2006 text to ensure correct interpretation and implementation.

Scope

This part of the ISO/IEC 13818 series defines the Advanced Audio Coding (AAC) bitstream syntax, coding tools, profiles and performance targets for MPEG‑2 AAC. It covers multi-channel coding, decoder model, and integration notes for using bandwidth‑extension techniques (e.g., SBR) and related transports. Corrigenda address editorial and technical corrections to ensure interoperable implementations.

Key topics and requirements

• Definition of AAC bitstream syntax and decoder model.
• Profiles, tool sets and signaling for MPEG‑2 AAC.
• Multi‑channel audio coding techniques and performance objectives.
• Guidance for use of bandwidth extension (SBR) in conjunction with AAC.
• Transport and metadata considerations (including provisions for MPEG Surround transport via amendments).
• Interoperability and conformance requirements for decoders and bitstreams.

Typical use and users

Implementers of audio codecs and decoders, broadcast and streaming system engineers, consumer electronics manufacturers (set‑top boxes, TVs, mobile devices), multimedia software developers, audio compression researchers, test and conformance labs, and standards bodies use this standard to implement and verify AAC encoding, decoding and transport.

FAQ

Q: What is this standard?

A: ISO/IEC 13818-7:2006 is the MPEG‑2 Advanced Audio Coding (AAC) specification (fourth edition, 2006). The designation "Cor 2:2010" refers to Technical Corrigendum 2 published in 2010 which corrects parts of the 2006 text.

Q: What does it cover?

A: It defines AAC bitstream format, coding tools, decoder model, profiles and guidance for combining AAC with bandwidth‑extension technologies (e.g., SBR) and for transport of advanced features like MPEG Surround (through amendments).

Q: Who typically uses it?

A: Codec implementers, device and consumer electronics manufacturers, broadcasters, streaming platform engineers, audio software developers, and conformance/test laboratories.

Q: Is it current or superseded?

A: The 2006 fourth edition with its published corrigenda and amendments remains the referenced edition of ISO/IEC 13818-7; the standard has been subject to routine review cycles. Users should check the issuing organizations for any later amendments, corrigenda or replacements when precise current status is required.

Q: Is it part of a series?

A: Yes. It is Part 7 of ISO/IEC 13818 (the MPEG‑2 suite). It is related to other parts of ISO/IEC 13818 and to ISO/IEC 14496 (MPEG‑4), particularly where AAC, SBR and related transports intersect.

Q: What are the key keywords?

A: AAC, MPEG‑2, audio coding, SBR, HE‑AAC, MPEG Surround, bitstream, decoder, ISO/IEC 13818-7, corrigendum.
