The perceptual relevance of such spatial audiovisual coherence is of significant interest. In this paper, we explain why the combination of accurate sound positioning and stereoscopic-3D images can lead to an incongruence between the sound and the image for multiple spectators. Then, we adapt to s-3D viewing a method originally proposed for 2D images in the literature to reduce this error. Finally, a subjective experiment is carried out to prove the efficiency of the method.

Applying this technique to synthesize virtual sources located within an indoor environment can create striking audio ef- fects in the context of virtual or augmented reality applica tions. However, interactions of the synthesized sound field with th e lis- tening room must be taken into account for they cause modifica - tions in the resulting sound field. This paper enumerates som e of these interactions according to different virtual scene co nfigura- tions and applications. Particular attention is paid to the repro- duction of the sound source directivity and to the reproduction of a room effect coherent with the real environment. Solutions for synthesizing the directivity of the source and the associat ed room effect are proposed and discussed around simulations, developpe- ments and first perceptual validation. 1. CONTEXT
