Abstract
This paper presents elaborations upon the beam tracing algorithm first introduced to acoustic research in 1998. Beam tracing for audio approximates reverberation filters present in physical architectural scenes by analyzing digital models of those scenes to compose the impulse responses of those filters. The algorithm as originally presented takes into account some of the acoustic absorption properties of the materials making up the scene. However, it has previously assumed that each surface which reflects or transmits sound does so at an even distribution across the space of audible frequencies. This paper describes a method for incorporating non-flat frequency responses of surfaces, which resolves this shortcoming. A survey of human subjects confirms that after these improvements, the algorithm produces more convincing and realistic filters.
