Abstract

By the use of cross-talk cancellation techniques, it is possible to reproduce binaural audio with loudspeakers. One drawback of such systems is that they have a very narrow sweet-spot, which constraints the listener to be in a specific position with respect to loudspeakers. As to overcome this difficult, a formulation has been developed that adapts the cross-talk cancellation filters of
a loudspeaker array to the listener´s position, which is estimated by means of a computer vision head- tracking system. To perform the adaptation, the cross-talk cancellation filters are decomposed into a series of gain-delay individual elements to control the radiation pattern of the loudspeaker array and a finite impulse response (FIR) equalisation filter. The formulation has been implemented in a loudspeaker array consisting of 28 small-size radiators, allowing a sweet-spot-free binaural reproduction for a single listener.
