A new rendering algorithm is introduced which allows to model a given room parameterized by a setof perceptual parameters. The processing-cost and memory requirements are minimized and thesystem is capable of reproducing a large number of sound sources and processing many differentlistening positions independently. Rather than reproducing a large number of reflections independently(as in mirror-image rendering or ray-tracing), sets of reflections are combined in a simple statisticalrepresentation of direction of incidence, diffuseness, absorption, etc. For all perceptual parameters astatistical representation is defined, which can easily be used to reproduce impulse responses for anynumber of reproduction channels from 2 up to n. For a high number of reproduction channels, wavefieldsynthesis techniques can be used to reproduce a complete sound-field, rather than a sweet-spotbased perception for one listening position.
