VIRTUALACOUSTICS

Virtual Acoustics (VA) creates audible sound from a purely virtual situation. To do so, it uses digital input data that is pre-recorded, measured, modelled or simulated. However, VA creates dynamic auditory worlds that can be interactively endevoured, because it accounts for modifications of the virtual situation. In the simplest case, this means that sound sources and listeners can move freely, and sound is changed accordingly. This real-time auralization approach can only be achieved, if certain parts of the audio processing are updated continuously and fast. We call this audio rendering, and the output is an audio stream that represents the virtual situation. For more complex situations like rooms or outdoor worlds, the sound propagation becomes highly relevant and very complex. VA uses real-time simulation backends or simplified models to create a physics-based auditory impression. If update rates are undergoing certain perceptive thresholds, this method can be readily used in..
