Sound localization systems aim at providing the position of a particular sound source as perceived by the human auditory system. Interaural level difference, interaural time difference, and spectral representations of the binaural signals are the main cues adopted for localization. When two sound sources are simultaneously active, a virtual source is created. In this paper a novel approach is presented to provide the human perception of a sound image created by two loudspeakers. The solution is based on both frequency-dependent binaural and monaural cues in order to consider the human auditory system sensitivity to spatial sound localization. Experimental results proved the effectiveness of the proposed approach in correctly estimating the horizontal and vertical position of the virtual source.
