Positions of the virtual sound sources p_src in the localization experiment (black symbols). The white area indicates the projection screen, the loudspeaker positions are represented as gray dots. Black crosses denote source positions with 0° elevation, triangles elevation > 0°, and squares elevation < 0°. Please note that not all rendering methods used all loudspeakers. Only the frontal part of the setup, i.e. the area including the virtual sound source positions, is shown here. The setup also involved loudspeakers at positions that are not shown here.
