%X The integration of the auditory modality in virtual re- ality (VR) is known to promote the sensations of im- mersion and presence. However it is also known from psychophysics studies that auditory-visual interaction obey to complex rules and that multisensory conﬂicts may disrupt the adhesion of the participant to the pre- sented virtual scene. It is thus important to measure the accuracy of the auditory spatial cues reproduced by the auditory display and their consistency with the spatial visual cues. This study evaluates auditory lo- calisation performances under various unimodal and auditory-visual bimodal conditions in a VR setup us- ing a stereoscopic display and binaural reproduction over headphones in static conditions. The auditory lo- calisation performances observed in the present study are in line with those reported in real conditions, sug- gesting that VR gives rise to consistent auditory and visual spatial cues. These results validate the use of VR for future psychophysics experiments with audi- tory and visual stimuli. They also emphasize the im- portance of a spatially accurate auditory and visual rendering for VR setups.
