Synthetic Transaural Audio Rendering (STAR): A Perceptive 3D Audio Spatialization Method

The synthetic transaural audio rendering (STAR) method aims at canceling the cross-talk signals between two loudspeakers and the ears of the listener (in a transaural way), with acoustic paths not measured but computed by some model (thus synthetic). Our model is based on perceptive cues used by the human auditory system for sound localization. The aim is to give the listener the sense of the position of each source rather than reconstruct the corresponding acoustic wave or field. Although the method currently focuses on the azimuth dimension, extensions to elevation and distance are now considered, for full 3D sound, with a discussion to conduct further works needed to improve overall quality and validate such extensions.
