This paper overviews the principles of the synthesis of virtual sound environments for application to the fields of music and multimedia production and to the design of advanced multimodal human-computer interfaces (e.g. virtual reality). A real-time spatial processor developed by Espaces Nouveaux and Ircam, the Spatialisateur, is presented. It allows to reproduce and control the localization of sound sources in three dimensions as well as the projection (reverberation) of sounds in an existing or virtual space. A specificity of the Spatialisateur project is the concern to provide direct control over the perceptual spatial attributes associated to each sound source and to the virtual space, while allowing reproduction via various systems or formats over loudspeakers or headphones. The operational advantages of this approach are illustrated in practical contexts.
