Audio technology - customized listening experiences in 3D | Joseph von Fraunhofer Prize 2023

Whether streaming music and movies, watching TV or in the car: The MPEG-H Audio system makes it possible to fully immerse yourself in soundscapes and adjust them to your own preferences. Three researchers from the Fraunhofer Institute for Integrated Circuits IIS @FraunhoferIIS - representing a large team - are being awarded the Joseph von Fraunhofer Prize 2023 for this development.
Turn up the volume on the TV movie dialogue, lower the background noise? Select your favorite sport commentator at the touch of a button? Or turn the drums down a bit while listening to music? The MPEG-H Audio system from the Fraunhofer Institute for Integrated Circuits IIS makes it easy to personalize 3D sound. For the development of the system, Harald Fuchs, Dr. Achim Kuntz and Adrian Murtaza - representing the team - will be awarded the Joseph von Fraunhofer Prize 2023.
The MPEG-H Audio system brings the three-dimensional world of sound to more and more playback devices. The process used for this clearly distinguishes the technology from Fraunhofer IIS from other 3D sound systems: Instead of using only classic audio tracks, the format works with audio objects. Such an object, for example a singing bird, is assigned properties such as position and volume through metadata. They are used to determine what happens to the sound: The birdsong moves in three-dimensional space, becoming louder and softer. All this information is sent to the playback system, where it is combined with information about the playback environment. Only now are the loudspeaker signals created - in contrast to usual surround formats such as 5.1 or 7.1.
The new approach of describing audio objects through metadata also enables content to be personalized: choosing between different languages, making movie dialogues louder and thus more understandable, positioning the voice of the sports commentator freely in the room, and hearing more or less audience sound at live events.
