MPEG-I Audio seeks to provide an immersive virtual audio and visual experience to users wearing a head-mounted visual display (HMD) with audio headphones, or using loudspeakers. The user’s view and perception of the virtual reality environment (VR) is responsive to user motion (i.e. position and orientation), where the user is free to move around in a certain bounding box. The audio rendering will also be responsive to interaction with selected virtual items. In a similar way, MPEG-I Audio will support augmented reality (AR) in which virtual objects and associated sounds are placed in the user’s view of the physical world. The project will use the existing MPEG-H 3D Audio Low Complexity Profile (ISO/IEC 23008-3) as a compression engine, and the to be standardized technology MPEG-I Immersive Audio (ISO/IEC 23090-4), as an audio rendering engine. The Call for Proposals for MPEG-I Immersive Audio was issued in April 2021 and submissions were evaluated in January 2022. It is expected that this standard will issue in 2023.
