Abstract

This paper focuses on a stereophonic play back system designed to adjust the ``sweet spot' to the listener's position. The system includes an optical face tracker which provides information about the listener's x-y position. Accordingly, the loudspeaker signals are manipulated in real-time in order to move the ``sweet spot'. The stereophonic perception with an adjusted ``sweet spot' is theoretically investigated on the basis of several models of binaural hearing. The results indicate that an adjustment of signals corresponding to the center of the listener's head does improve the localization over the whole listening area. Although some localization error remains due to asymmetric signal paths for off-center listening positions, which can be estimated and compensated for.
