A unified approach to electronic simulation of auditorium acoustics
Jeffrey Borish · The Journal of the Acoustical Society of America · 1982
A unified approach to simulating auditorium acoustics electronically is described. The technique begins with a modeling phase in which the geometry and acoustical characteristics of an auditorium are programmed into a computer. The computer calculates the directional impulse response characterizing the transmission of sound from the source to the listener. The impulse response is convolved with an audio signal in real time by using a high-speed transversal filter. The result of the convolution can be presented to a listener with a few speakers and still achieve a result which is natural-sounding and realistic.
