AES Europe 2025

In this session, we propose a path for the evolution of immersive audio technology towards accelerating commercial deployment and enabling rich user-end personalization, in any linear or interactive entertainment or business application. We review an example of perceptually based immersive audio creation platform, IRCAM Spat, which enables plausible aesthetically motivated immersive music creation and performance, with optional dependency on physical modeling of an acoustic environment. We advocate to alleviate ecosystem fragmentation by showing: (a) how a universal device-agnostic immersive audio rendering model can support the creation and distribution of both physics-driven interactive audio experiences and artistically motivated immersive audio content; (b) how object-based immersive linear audio content formats can be extended, via the notion of Acoustic Objects, to support end-user interaction, reverberant object substitution, or 6-DoF navigation.
