Training and Simulation Get Spatial Audio Standard

⊲ audioXpress ⊳ MPEG-I Immersive Audio brings standardised 6DoF sound to VR, AR and mixed reality through compressed scene metadata and a normative renderer. It models geometry, materials, occlusion, diffraction, portals, reverberation, distance and movement, allowing audio to respond naturally as users move through virtual spaces. Compatible with MPEG-H 3D Audio, it reduces reliance on proprietary pipelines and manual audio tuning, with applications spanning simulation, industrial training, maintenance, inspection and digital twins where accurate spatial cues can support situational awareness.
⊲ Fraunhofer IIS researchers Andreas Silzle and Sascha Disch frame MPEG-I as ending years of proprietary audio lock-in, forcing device makers to compete on quality within one shared ISO/IEC specification. ⊳
