Spatial audio quality in regard to 3D video

Samuel Moulin , Rozenn Nicol , Laetitia Gros

3D movies provide an improved immersion in terms of visual perception. As for the associate audio channels, most of them are mixed for the conventional format of “multichannel 5.1”. It should be considered that today there are various ways of listening to 5.1 audio content, either over loudspeaker arrays (for instance ITU standard 5.1 set-up), or over headphones. Recently sound projectors were introduced, in order to render surround sound with compact equipments. The choice of the solution to render multichannel audio has obviously an impact on the perceived quality of the sound. In addition, this latter will also depend on whether a visual content is presented in combination with the audio content. This paper will re-examine these issues in the new context of 3D video. The perceived quality of the spatial sound will be assessed by a listening test for a set of audiovisual excerpts of a 3D movie.
