AAC? Is it really better than MP3?

This page contains information and resources related specifically to AAC. Other MPEG Audio resources are listed on the Audio or MP3 pages.

AAC (Advanced Audio Coding) is one of the audio compression formats defined by the MPEG-2 standard. AAC used to be called NBC (Non-Backward-Compatible), because it is not compatible with the MPEG-1 audio formats. MPEG-2 also defined another audio format called MPEG-2 Multichannel or MPEG-2 BC (Backward Compatible), which is compatible with MPEG-1.

AAC is more efficient than MP3 (MPEG-1 Layer 3) and is the state of the art in audio compression technology.
