Advanced Audio Coding (AAC) is a multichannel perceptual audio coding standard: it compresses audio while aiming to preserve the sound people hear. AAC describes the coding technology, not one fixed bitrate or a guaranteed level of sound quality.
What does AAC stand for?
AAC stands for Advanced Audio Coding. It is a way of encoding audio so that it takes less data to store or transmit while retaining perceived sound quality. The standard allows for audio coding; the result depends on encoding settings and listening conditions.
What standard defines AAC?
ISO/IEC 13818-7:2006 specifies MPEG-2 AAC as a multichannel audio coding standard. ISO’s catalog lists the edition as published in January 2006 and says it was reviewed and confirmed in 2017, leaving that edition current in the catalog. The catalog also notes one amendment. ISO/IEC 13818-7:2006 describes AAC as delivering higher quality than is achievable when requiring MPEG-1 backwards compatibility.

AAC is part of a wider standards landscape, not a single quality setting for every situation. MPEG-4 Audio is a broader framework intended to address different types of sound and delivery needs, including speech and music, natural and synthetic audio, low bitrates and high-quality applications, and complex soundtracks. MPEG’s MPEG-4 Audio overview provides that context.

Does AAC have a particular bitrate or sound quality?
No single bitrate or quality level follows from the name AAC. In an October 2005 overview, MPEG characterized AAC as a multichannel perceptual audio coder and said stereo audio material coded at 128 kb/s could achieve transparent quality relative to a stereo Compact Disc original. That is MPEG’s characterization for the stated material and comparison—not a universal minimum, modern benchmark, or promise for every recording, encoder, or listener. MPEG document N7704, authored by S. Quackenbush, contains the statement.
What AAC does—and does not—tell you
- It tells you about audio coding: AAC is the standard or codec technology used to encode audio.
- It does not specify one sound result: settings and listening conditions affect perceived quality.
- It does not identify a particular device or product: the definition alone does not establish that special hardware or software is required.
The standard’s definition also does not, by itself, establish a file container, filename extension, device compatibility, or which codec is best for a particular use. Those details require information about the specific format, device, or application.
