The MPEG-I Immersive Audio standard for Virtual;
Augmented Reality (VR/AR) audio with six degrees of freedom
(6DoF) was completed in November 2025 by the MPEG Audio
group (ISO/IEC JTC 1/SC 29/WG 6)). It offers compressed
representation of virtual audio scenes as well as an
efficient; acoustically sophisticated rendering to both
head-tracked binaural headphones; loudspeaker setups.
The latter is a unique feature among VR/AR audio
specifications; enables convincing reproduction of
conventional stereo, surround; 3D material with a large
sweet area in home entertainment setups for a single
tracked user, without the need for a head-mounted
display. This paper describes the technology of MPEG-I
Audio listener-tracked loudspeaker rendering as a
stand-alone application with a special focus on practical
considerations for optimal room calibration.
