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 on the horizontal plane. Recently, the authors proposed a hybrid system that combines HRTF-based spectral filtering with WFS. This system makes use of the conventional WFS approach to achieve localization in the horizontal plane, whereas elevation effects are simulated by means of spectral elevation cues. This paper provides a review of the proposed method together with a compilation of the last experiments carried out to evaluate the perception of elevated sources in this novel system.
