Edition - 1: Immersive Audio

Publication Year: 0
Status: ongoing
Motivations: MPEG-H 3D Audio supports a 3DoF (yaw, pitch, roll) user experience at the movie "sweet spot," but it is desired to extend this to 6 DoF (adding x, y, z).
Objectives: MPEG-I Audio builds upon MPEG-H 3D Audio to provide an immersive audio VR experience with 6 DoF. MPEG-I Audio standardizes additional metadata and rendering technology that delivers a compelling user experience with full 6DoF freedom of navigation.
