Traditional 3D audio systems often have a limited sweet spot for
the user to perceive 3D effects successfully. In this paper, we
present a personal 3D audio system with loudspeakers that has
unlimited sweet spots. The idea is to have a camera track the
user’s head movement, and recompute the crosstalk canceller
filters accordingly. As far as the authors are aware of, our system
is the first non-intrusive 3D audio system that adapts to both
the head position and orientation with six degrees of freedom.
The effectiveness of the proposed system is demonstrated with
subjective listening tests comparing our system against traditional
non-adaptive systems.
