AB  - The MPEG-I immersive audio standard [1] for compressed audio representation and rendering for Virtual and Augmented Reality (VR/AR) applications with six degrees of freedom (6DoF) was technically completed in January 2025 by the MPEG Audio group (ISO/IEC JTC 1/SC 29/WG 6). This standard enables efficient bitrate management, high-quality storage, and transmission of virtual environments, including audio sources with spatial dimensions and specific radiation traits (such as musical instruments), along with geometric description of acoustically relevant scene details (e.g., walls, doors, sound reflecting, and occluding elements). The audio rendering process incorporates comprehensive modeling of room acoustics and intricate acoustic phenomena, including occlusion, reflection, and diffraction caused by sound obstacles, Doppler effect, and dynamic environment changes triggered by user interactivity. This paper presents its finalized technology.
