Immersive audio - or 3D-audio - enables a new realism in sound reproduction by adding elevated speakers above or below the listeners. With the MPEG-H Audio System and its available production and authoring tools for live- and post-productions, mixing 3D immersive sound was never easier!
With MPEG-H Audio, listeners can interact with the audio elements and choose from different languages or commentators or even change the position of audio objects. The configuration of user interactivity is always under the full control of the content creator.
The MPEG-H Audio System is designed to work in streaming systems as well as in existing and future broadcast systems from contribution to emission. In numerous trials around the globe, broadcast specialists experienced the easy integration into their existing workflows.
The MPEG-H Authoring Suite (MAS) is a set of tools that make the production of MPEG-H Audio content easier, faster, more intuitive and more powerful. They support the recently published MPEG-H ADM Profile, as well as binaural monitoring for immersive audio reproduction over headphones.

The MPEG-H Authoring Plug-in takes you through all the steps of creating object- or channel-based MPEG-H Audio productions inside a VST3- or AAX-enabled Digital Audio Workstation (DAW). You will be able to export your immersive and interactive MPEG-H Audio scenes to either MPEG-H Production Format (MPF), or MPEG-H BWF/ADM, containing audio and metadata, ready for distribution via MPEG-H-enabled channels.
The MPEG-H Authoring Tool is a new software tool for Mac and Windows for creating MPEG-H metadata with existing audio material. The MPEG-H Authoring Tool allows for easy MPEG-H authoring without the need of a Digital Audio Workstation. You can define specific MPEG-H parameters, instantly listen to your configurations and export your authored mixes either as MPEG-H Production Format (MPF), MPEG-H BWF/ADM or as a template export in an XML file.
Immersive audio or 3D-audio mixing for home delivery is done using loudspeakers in an audio control room or near field mixing environment.
Fraunhofer with its extensive experience in 3D-audio mixing, and in setting up studios as well as listening rooms can provide all the structural requirements and technical specifications for a 3D-audio production environment for accurate mixing and reproduction in a flexible manner for loudspeaker reproduction systems ranging from 1.0 up to 7.1+4H channel layouts.
Fraunhofer offers consultation for room geometry and room acoustics, loudspeaker positioning and electroacoustic performance, 3D-audio monitoring and mixing capabilities and provides recommendations for related literature.

The Audio Definition Model (ADM) according to ITU-R BS.2076 defines an open metadata format for production, exchange and archiving of Next Generation Audio (NGA) content in file-based workflows. Its comprehensive metadata syntax allows describing many types of audio content including channel-, object-, and scene-based representations for immersive and interactive audio experiences. A serial representation of the Audio Definition Model (S-ADM) is specified in ITU-R BS.2125 and defines a segmentation of the original ADM for use in linear workflows such as real-time production for broadcasting and streaming applications.
The MPEG-H ADM Profile defines constraints on ITU-R BS.2076 and ITU-R BS.2125 that enable interoperability with established NGA content production and distribution systems for MPEG-H Audio as defined in ISO/IEC 23008-3.
The freely available Fraunhofer ADM Info Tool is a software utility that provides support in creating profile-conform ADM metadata. Its conformance check framework runs input ADM metadata against an exhaustive set of checks derived from the MPEG-H ADM Profile, gathering detailed reports of any encountered conformance issues and providing information on how to resolve them.
Fraunhofer has an interdisciplinary team of researchers, engineers and Tonmeisters. We support production teams on-site during live broadcast trials. We can offer seminars for MPEG-H production at our headquarters in Erlangen, Germany, or even on site at broadcast studios around the world. We also offer offline tutorial series and provide dedicated training material to fit your needs. Please contact us for details.
