Realisation of an Adaptive Cross-talk Cancellation System for a Moving Listener
The adaptive system described in this paper is based on the static cross-talk cancellation. The main task for an adaptive system is to update the cross-talk cancellation filter depending on the listener's position. The required filter is calculated at run-time of the program. Depending on the head position, the HRTFs required for the filter calculation will be selected from a data base. The conclusion of the a preliminary listening test is that the dynamic cross-talk cancellation produces impressive results. The listener can move in an area of about 1 m2. Head rotation is possible within the angle spanned by the loudspeakers.
