The DIVA auralization system
msra(2001)
摘要
This is the position paper of DIVA sound group for Acoustic Rendering Campfire. In this paper we briefly overview the DIVA auralization system and also tell our except- ations related to this Campfire. In VAE creation our ultimate goal has been to develop a sound rendering application that can be used in acoustic design. In its ideal form an authentic reproduction of a real envir- onment would be indistinguishable from the real environment without any exception (4). Of course, this is not possible because of simplifications that have to be made in room acoustic modeling. We try to do plausible, perceptually authentic, auralization that can be used as a reliable tool in room acoustics design. We know very well that the rendering with same level of naturalness can be implemented with more efficient algorithms with perceptual modeling. However, our starting point has been to take the room geometry and all the physics-based data that we can get and with this information to realize natural sounding auralization. To achieve this ambitious goal, we utilize the DIVA auralization system which is a physics- based room acoustic modeling and auralization system that does rendering in time domain. The applied auralization method enables dynamic rendering (also in real time) with normal PC (without any additional DSP-cards), running Linux operating system.
