SoundToolKit is a 3D realtime game audio library utilizes beam tracing 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. A short films of the current version of the system are available at:

Software works in a similar fashion as tools like CATT Acoustics, but calculations are conducted in real time. SoundToolkit is a result of RAYAV project conducted in a consortium of and .
