  title={Accelerated Beam Tracing Algorithm},
  author={Samuli Laine and Samuel Siltanen and Tapio Lokki and Lauri Savioja},
Determining early specular reflection paths is essential for room acoustics modeling. Beam tracing algorithms have been used to calculate these paths efficiently, thus allowing modeling of acoustics in real-time with a moving listener in simple, or complex but densely occluded, environments with a stationary sound source. In this paper it is shown that beam tracing algorithms can still be optimized by utilizing the spatial coherence in path validation with a moving listener. Since the… CONTINUE READING
