Erlangen, Germany (September 18, 2013)—The Moving Picture Experts Group (MPEG) standardization body has selected the Fraunhofer IIS channel/object-based proposal as a basis for the future MPEG-H 3D Audio standard.

Following a testing and selection process that included a total of 10 test labs worldwide, more than 50 listeners and more than 41,000 subjective responses, MPEG selected the Fraunhofer IIS channel/object-based proposal to provide a basis for the future high-quality 3D audio content delivery standard.

Submissions from leading audio research facilities across the globe were considered and tested for two use-cases: channel/object-based and scene-based audio signals. Fraunhofer's proposal consisted of an Extended HE-AAC based audio codec and a 3D rendering engine. This technology supports the transmission of 3D audio signals and flexible rendering for the playback of 3D audio in a wide variety of listening scenarios. These include 3D home theater setups, 22.2 loudspeaker systems, automotive entertainment systems and playback over headphones connected to a tablet or smartphone.

"Fraunhofer IIS is proud to develop leading audio technologies that meet the high standards of MPEG," Harald Popp, head of the audio and multimedia business department at Fraunhofer IIS, stated. "Similar to previous standardization activities of MPEG, Fraunhofer IIS's proposal was selected once again for its superior audio quality and performance," he added.

The winning channel/object-based and scene-based proposals will be merged in the future standardization process to be finalized in early 2015.
