Résumé

This paper overviews the principles and methods for synthesizing complex three-dimensional sound scenes by processing multiple individual source signals. Signal processing techniques for directional sound encoding and rendering over loudspeakers or headphones are reviewed, as well as algorithms and interface models for synthesizing and dynamically controlling room reverberation and distance effects. A real-time modular spatial sound processing software system, called Spat, is presented. It allows reproducing and controlling the localization of sound sources in three dimensions and the reverberation of sounds in an existing or virtual space. A particular aim of the Spatialisateur project is to provide direct and computationally efficient control over perceptually relevant parameters describing the interaction of each sound source with the virtual space, irrespective of the chosen reproduction format over loudspeakers or headphones. The advantages of this approach are illustrated in practical contexts, including professional audio, computer music, multimodal immersive simulation systems, and architectural acoustics.
