A method for acoustically and perceptively characterising stereophonic phenomena is applied using the velocity vector. The latter is first defined as a synthetic descriptor of local acoustic properties in any sound field, from which localisation cues can be objectively derived. When applied to sound imaging systems, usual laws and artefacts are interpreted, and compromises are highlighted depending on the loudspeaker geometry.
