ISO/IEC JTC 1/SC 29/WG 6 - MPEG Audio coding

This document specifies technology that supports the real-time interactive rendering of an immersive virtual or augmented reality audio presentation while permitting the user to have 6DoF movement in the audio scene. It defines metadata to support this rendering and a bitstream syntax that enables efficient storage and streaming of immersive audio content.

This document contains simulation software for the MPEG-H 3D audio standard as defined in ISO/IEC 23008-3.

This document specifies technology for loudness and dynamic range control (DRC). It is applicable to most MPEG audio technologies. It offers flexible solutions to efficiently support the widespread demand for technologies such as loudness normalization and dynamic range compression for various playback scenarios.

This document contains simulation software for the Unified speech and audio coding standard as defined in ISO/IEC 23003-3.

This document specifies technology that supports the efficient transmission of immersive audio signals and flexible rendering for the playback of immersive audio in a wide variety of listening scenarios. These include home theatre setups with 3D loudspeaker configurations, 22.2 loudspeaker systems, automotive entertainment systems and playback over headphones connected to a tablet or smartphone.

This document specifies conformance criteria for both bitstreams and decoders compliant with the MPEG-D Unified speech and audio coding standard as defined in ISO/IEC 23003‑3. This is done to assist implementers and to ensure interoperability.
