Sound Source Radiation Syntheses: From Performance to Domestic Rendering

Abstract

A diffusion device based on a digitally-controlled 3D array of loudspeakers ? La Timée ? was developped in order to synthesize a given radiation pattern from the combination of a set of elementary directivities. This radiation synthesis method, designed for musical and performance constraints (real-time control, musical vocabulary associated to different directivity patterns, ?), has been used for stage performances and sound installations. In order to translate the sound experience for domestic setups, the paper also addresses the post-production step where the spatial image associated to the radiation synthesis is transcoded on conventional formats like transaural, ambisonic or 5.1 formats. The method is based on the characterization of the performance room thru the different elementary directivities, and then on their superimposition.
