Abstract: Efficient computation with low latencies is important for rendering interactive, virtual acoustics, especially on mobile devices. In Ambisonic rendering, the computational costs are increasing with the spatial resolution. It is known that direct sound requires a spatial resolution exceeding the order of 3 to be rendered perceptually accurate on headphones, and rendering of the diffuse late part of spatial impulse responses mainly requires preserving the binaural covariance. This study evaluates the perceptual requirements for the intermediate, early reflections. The evaluation employs various settings (e.g. audio material, room size, source position, number of reflections) and compares lower-order playback to a 7th-order reference using head-tracked binaural Ambisonics.
