In this paper high-quality model-based sound synthesis of plucked string and woodwind instruments is combined with room simulation and auralization techniques. The result is a real-time virtual three-dimensional room where the listener and multiple virtual instruments can be moved. The system was designed using signal processors in a multiprocessing environment. Sound radiation patterns of musical instruments were measured and direction-dependent filtering was applied to instrument simulation models. Auralization is achieved by measuring and using head-related transfer functions. The binaural three-dimensional audio output of the virtual environment is directed to headphone listening. The environment is controlled by a mouse-operated user interface while the virtual instruments are played via MIDI.
