The Use of a Digital Audio Mainframe for Room Acoustical Auralization
Jens Holger Rindel, Claus Lynge, Graham Naylor, Kim Rishoj · 1994
A new user-friendly method for auralization has been developed by interfacing a digital audio mainframe and a room acoustical computer model. Instead of using a convolution technique, early reflections are created by time delays and late reflections byan electronic reverberation processor. The system is verified through measurements of a number of room acoustical parameters on the terminals of the mainframe. 0 INTRODUCTION In recent years many researchers have been working on techniques for auralization of the calculation results from room acoustical computer models. An overview has been presented by Kleiner [1], and it appears that methods for binaural presentation considered until now are based on the convolution of room impulse responses with time sequences of anechoic recordings. This implies in principle that the individual head-related transfer functions must be known at a large number of angles of incidence, and the corresponding impulse responses for the two ears should ...
