Standards Review: Considerations for the MPEG-H Audio Standard

July 31 2015, 10:00

This article discusses the plan for the new MPEG-H Audio standard, a real-time 3-D audio encoder system with applications for broadcast and streaming distribution, developed in large part by the Fraunhofer Institute in Germany, and recently finalized and submitted as an ISO/MPEG standard. It features a contribution by Robert Bleidt, titled “Delivering Multi-Platform Immersive Audio with the New MPEG-H Audio Standard.”

MPEG-H is a group of standards under development by the ISO/IEC Moving Picture Experts Group (MPEG) for a digital container standard, a video compression standard, an audio compression standard, and two conformance-testing standards.

The group of standards is formally known as ISO/IEC 23008—high-efficiency coding and media delivery in heterogeneous environments. MPEG-H Audio is just the third part of 13 document chapters and basically covers the codec for 3-D audio, which supports: an object-audio codec for “interactive sound mixing;” a realistic audio experience with additional front- and rear-height speaker channels to traditional surround sound setups; and higher order ambisonics (HOA), a technique for reproducing
a complete spherical soundfield to provide a fully immersive live sound experience.

The basic MPEG-H audio technology, which is under discussion for publication as an ISO/IEC international standard, results basically from cooperation between the Fraunhofer Institute for
Integrated Circuits IIS, Technicolor, and Qualcomm.
