Wave Field Synthesis systems are known to suffer from coloration. Depending on the applied number of loudspeakers comb-filter effects are present in the amplitude spectrum. In a listening experiment participants rated the perceived coloration of a synthesized point source compared to the reference case of a single loudspeaker. The point source was presented by two-channel stereophony and Wave Field Synthesis applying a circular loudspeaker array ranging from 14 up to 3 584 loudspeakers. Test participants were placed at different positions in the audience area for Wave Field Synthesis. The whole experiment was done using binaural synthesis.
