Abstract

Auralization in room acoustics is created by the convolution of an anechoic audio signal with the RIR (room impulse response), either computed or measured at the receiver location. When headphones are used for reproduction, the same auralized signal is often sent to both ears, for simplicity.

This paper addresses the computation of directional impulse responses by a sound ray program. These responses are used in the convolution process in combination with HRTFs to simulate not only the room reverberation, but also the angular location of all sound contributions to the receiver. Computational problems include the separate treatment of specular and diffuse reflections and the compromise between computing time, the number and the accuracy of directional RIRs.
