Rear and side reproduction of elevated sources in Wave-Field Synthesis

Wave-Field Synthesis (WFS) is a spatial sound reproduction technique that has attracted the interest of many researchers in the last decades. Unfortunately, although WFS has been shown to provide excellent localization accuracy, this property is restricted to sources located in the horizontal plane. In order to deal with this problem, a spectral-filtering-based solution has been recently proposed for achieving slight elevation effects. This paper reports new experiments regarding side and rear reproduction of elevated virtual sources in WFS. Results show that elevation can be also perceived in these cases, confirming the validity of the spectral-filtering approach.
