The invention is a crosstalk canceler wherein different frequency bands
are canceled at different locations so as to allow greater listener
movement about the "sweet spot" while maintaining effective crosstalk
cancellation. A spectrally smooth canceler equalization is used, reducing
artifacts for listeners away from the sweet spot and further enlarging
the sweet spot. Finally, the canceler equalization is adapted to either
the anticipated or the actual crosscoherence among the input channels,
producing a natural equalization regardless of the input.
