ScatAR: a mobile augmented reality application that uses scattering delay networks for room acoustic synthesis

We present 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 allows for real-time processing and updating of reflection path geometry. It provides a proof-of-concept for plausible audio-spatial registration of a virtual object in a real environment, but further tests are needed in perceptual evaluation.
