Description of MPEG Advanced Audio Coding Introduction. Advanced Audio Coding (AAC) is a wideband perceptual audio coding algorithm that provides state of the art levels of compression for audio signals. AAC is primarily available as MPEG AAC Profile technology, which comprises the AAC Low Complexity technology. Motivation

https://www.loc.gov/preservation/digital/formats/fdd/fdd000036.shtml
Description. Perceptual audio encoding format designed for efficient distribution of waveform sound over moderate bandwidth connections; may be used at higher data rates for better fidelity. The compression approach adopted as a part of MPEG-2 has been further refined within MPEG-4; see also AAC_MP4.

MPEG Audio Coding selects 6DoF Technology for MPEG-I Immersive Audio. MPEG had previously issued a Call for Proposals (CfP) for 6DoF immersive audio technology in April 2021 for convincing Virtual Reality (VR) and Augmented Reality (AR) experiences. At the 137 th MPEG meeting, submissions to this CfP were reviewed and technology was selected ...
