Efficient Models for Reverberation and Distance Rendering in Computer Music and Virtual Audio Reality
Jean-Marc M. Jot · 1997
This paper discusses efficient digital signal processing algorithms for real-time synthesis of dynamically controllable, natural-sounding artificial reverberation. A general modular framework is proposed for configuring a spatial sound processing and mixing system according to the reproduction format or setup and the listening conditions, over loudspeakers or headphones. In conclusion, the implementation and applications of a spatial sound processing software are described, and approaches to control interface design and effective distance effects are reviewed. 1 Introduction Immersive real-time audio requires synthesizing and dynamically controlling directional panning and room reverberation effects over headphones or loudspeakers. Artificial reverberation is necessary to ensure a convincing degree of realism of the virtual sound scene and provide control over the perceived distance of virtual sound sources. Applications of spatial sound processing and artificial reverberation techniq...
