Submission + - RAYA - realtime audio engine simulation in Quake (youtube.com)
bziolko writes: RAYA is a realtime game audio engine that utilizes beamtracing to provide user with realistic audio auralization. All audio effects are computed based on the actual geometry of a given game level as well as its acoustic properties (acoustic materials, air attenuation). The sound changes dynamically along with movement of the game character and sound sources, so the listener can feel as if they were right there — in the game.
