Abstract: Directional Audio Coding (DirAC) for virtual worlds provides a new set of tools to synthesize sound sources in virtual worlds. In this paper, two methods are proposed that use projection of real and virtual auditory environments onto 3D-surfaces in a virtual world. The first method projects a B-format recordings onto an arbitrary surface by analyzing the spatial properties of time-frequency tiles of the input signals and by distributing them to the surface. The result is an ability to move in relation to the original microphone position in B-format recordings. The second method similarly projects room reverberation onto a surface in a doorway between two rooms, thus simulating the audible reverberation to the listener through a doorway. Informal listening suggests that the proposed methods provide a perceptually believable result.
