Abstract : Sound plays an important role in immersion when consuming content in eXtended reality (AR/VR). Modeling the acoustics of the virtual/real space one occupies is a key element in engagement and immersion. Multichannel spatial content must be adapted to mimic the acoustics of a space, and rendered binaurally over headphones. This talk will focus on modeling late reverberation for AR/VR, and discuss the optimum techniques for different scenarios with a focus on low-latency, real-time methods that provide perceptual plausibility. Particular focus will be given to delay-network based parametric reverberators that can be tuned to emulate a space and can be run in real-time.
