Download Monitoring distance effect with wave field synthesis
Wave Field Synthesis (WFS)  rendering allows the reproduction of virtual point sources. Depending on source positioning, the wave front synthesized in the listening area exhibits a given curvature that is responsible for a spatial perspective sensation. It is then possible to monitor the distance of a source with a “holophonic distance” parameter concurrently with conventional distance cues based on the control of direct/reverberation ratio. Presentation of this holophonic distance is made and then discussed in the context of authoring sound scenes in WFS installations. Three goals to this work: Introducing WFS to sound engineers in an active listening test where they manipulate different parameters for the construction of a sound scene. Assessing the perceptual relevance of the holophonic distance modifications. Studying the possible link between the holophonic distance parameter and conventional subjective distance parameters traditionally used by sound engineers.
