Abstract:

A variety of tools are available for the simulation of virtual acoustic environments. For a plausible simulation of acoustic environments, not only the direct sound and early reflections are needed, but also the late, typically diffuse, components of the reverberation. Since simulating late reverberation using image source models is computationally very inefficient, many tools use separate simulation methods for the early and late parts of the acoustic path. Late reverberation can be simulated using feedback delay networks (FDNs). In this talk, we will present an FDN in the Ambisonics domain that rotates the sound field at each reflection. With this approach, spatial scattering of the sound field can be achieved. In addition to applications in auditory research to simulate diffuse reverberation, artistic applications where this approach can be used to precisely shape the rotation and dispersion of the reverberant sound field will also be discussed.
