We have previously presented an augmented reality (AR) audio application, where scattering delay networks efficiently generate and organize a reverberator, based on room geometry scanned by an AR device. The application allowed for real-time processing and updating of reflection path geometry and provided a proof-of-concept for plausible audio-spatial registration of a virtual object in real environments. Here we present our ongoing work that aims to extend the simulation to outdoor scenes by using the Waveguide Web, instead of the original formulation with the Scattering Delay Networks. The current implementation is computationally more demanding, but has a potential to provide more accurate second-order reflections, and therefore, better registering of audio-visual AR scenes.
