MPEG-H Audio—The New Standard for Universal Spatial/3D Audio Coding

Document Thumbnail

In order to facilitate high-quality bitrate-efficient distribution and flexible reproduction of 3D sound, the MPEG standardization group is engaged in the development of MPEG-H Audio Coding. This proposed standard will allow for universal carriage of encoded 3D sound from channel-based, object-based, and HOA-based sound formats. Reproduction is supported for many output setups ranging from 22.2 and beyond down to 5.1, stereo, and binaural reproduction. Depending on the available reproduction configuration, the encoded material is rendered to yield the highest spatial audio quality, overcoming the incompatibility between various 3D reproduction formats. Moreover, MPEG-H Audio is a unified system for carriage of channel-oriented, object-oriented, and Higher Order Ambisonics-based content. This paper describes the current status of the standardization project and provides an overview of the system architecture, technology, capabilities, and current performance.
