TASCAR (Toolbox for Acoustic Scene Creation and Rendering) is a research toolkit for rendering virtual acoustic environments.

TASCAR is provided under GNU GPL v2. https://github.com/HoerTech-gGmbH/tascar

Research

TASCAR is being developed  in co-operation with University of Oldenburg. It is the core rendering software for the Gesture Lab and the 3D Virtual Reality Lab at UOL. HTCH and UOL cooperate closely in the domains of virtual reality reproduction and behavioural interaction studies.

Technology

Moving sound sources are simulated physically correct; air absorption and Doppler effect are taken into account. A mirror sound source model with simple reflection parameters enables static and dynamic moving reflectors. The simulation takes place in real time in the time domain and thus enables interactive positioning of objects, e.g. control of the listener position via body motion trackers. The output signal can be reproduced in Higher-Order Ambisonics (HOA), Vector-Base Amplitude Panning (VBAP) or binaural via headphones. Generic or individual 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 connect to the Blender game engine.

The software only runs under Linux operating systems.
