Auralization of room acoustics by Wave Field Synthesis based on array measurements of impulse responses

Wave Field Synthesis (WFS) enables correct spatial reproduction of acoustic events for larger groups of people. Such events often include acoustic information of the recording space which is then “auralized” after convolution with the sound sources. The acoustic information is acquired by measuring impulse responses. Spatial information is only obtained when the responses are measured along arrays (e.g., linear or circular) of microphone positions. In the presentation it will be explained how the measured datasets are parameterized and processed to be reproduced in the most efficient way: significant data reduction is possible due to the limited ability of the human hearing system to discriminate temporal and spatial details.
