AB  - With 3D picture being the driving force of today’s motion picture production, there is a growing need for adequate audio solutions, e.g. spatial audio algorithms for reproduction with flexible loudspeaker setups. While these reproduction systems will have to fulfill high quality demands, the amount of loudspeakers needed should be kept as low as possible to optimize commercial aspects. One suitable algorithm from a quality point of view is Wave Field Synthesis (WFS), which, however, requires a huge amount of speakers if implemented as stated in literature. This paper presents the results of a perceptual evaluation of a new algorithm based on WFS. A listening experiment has been performed to compare state-of-the-art WFS, the new algorithm, and Vector Base Amplitude Panning regarding localization and coloration.
