Auralization Applying the Parametric Room Acoustic Modeling Technique - the Diva Auralization System

The primary goal of this paper is to give a general view on room acoustic modeling and auralization, and especially to describe the current status of the DIVA auralization system. We have been building the system for several years, and it has evolved a lot during that time. It is a room acoustic modeling and auralization system suitable for both real-time and non-realtime acoustic rendering, and it is designed for research purposes. It applies the parametric room impulse response rendering technique described in the article. In this paper we review the architecture and design principles of the system. A description of recent advances is given and results of perceptual evaluations are presented.
