Abstract: Methods, systems, and computer readable media for supporting source or listener directivity in a wave-based sound propagation model are disclosed. According to one method, the method includes computing, prior to run-time, one or more sound fields associated with a source or listener position and modeling, at run-time and using the one or more sound fields and a wave-based sound propagation model, source or listener directivity in an environment.

Abstract: The subject matter described herein includes a method for simulating directional sound reverberation. The method includes performing ray tracing from a listener position in a scene to surface as visible from a listener position. The method further includes determining a directional local visibility representing a distance from a listener position to nearer surface in the scene alone each ray. The method further includes determining directional reverberation at the listener position based on the directional local visibility. The method further includes rendering a simulated sound indicative of the directional reverberation at the listener position.

Abstract: Methods, systems, and computer readable media for simulating sound propagation are disclosed. According to one exemplary method, the method includes decomposing a scene having at least one object into at least one near-object region and at least one far-object region. The method also includes generating at least one transfer function for the at least one near-object region, wherein the at least one transfer function maps an incoming sound field reaching the at least one object to an outgoing sound field emanating from the at least one object, wherein the incoming sound field is based on a geometric acoustic technique and the outgoing sound field is based on a numerical acoustic technique. The method further includes utilizing the at least one transfer function to perform simulation of sound propagation within the scene.

Abstract: Methods, systems, and computer program products for simulating propagation of sound in a static scene can be operated for pre-computing a transfer operator for simulating results of sound reflection within a modeled scene, simulating distribution of sound energy from a sound source positioned within the scene, applying the transfer operator to the distribution of sound energy from the sound source to compute simulated sound at a plurality of points within the scene, and simulating collection of sound energy from the plurality of points within the scene to a listener positioned within the scene.

Abstract: Methods, systems, and computer program products for simulating sound propagation can be operable to define a sound source position within a modeled scene having a given geometry and construct a visibility tree for modeling sound propagation paths within the scene. Using from-region visibility techniques to model sound diffraction and from-point visibility technique to model specular sound reflections within the scene, the size of the visibility tree can be reduced. Using the visibility tree, an impulse response can be generated for the scene, and the impulse response can be used to simulate sound propagation in the scene.
