TASCAR - Toolbox for Acoustic Scene Creation and Rendering
TASCAR (Toolbox for Acoustic Scene Creation and Rendering) is a research toolkit for rendering virtual acoustic environments. TASCAR is developed in collaboration with the University of Oldenburg. It is the central rendering software for the Gesture Lab and the 3D Virtual Reality Lab at UOL. HTCH and UOL are working closely together in the areas of virtual reality reproduction and behavioral interaction.

Moving sound sources are simulated in a physically correct way; air absorption and Doppler effect are taken into account. A mirror sound source model with simple reflection parameters allows static and dynamic moving reflectors. The simulation takes place in real time in the time domain, allowing interactive positioning of objects, e.g. control of listener position via body motion trackers. The output signal can be played back in Higher-Order Ambisonics (HOA), Vector-Base Amplitude Panning (VBAP) or binaurally via headphones. Generic or custom HRTFs can be used for binaural output.
An interface for synchronization with video sources or interactive computer graphics is available via Open Sound Control (OSC). In principle, there are possibilities to interface with the Blender Game Engine or the Unreal Game Engine.
