Abstract

A method of sound reproduction for reproducing sound by way of a plurality of loudspeakers comprises the steps of determining wherein a defined space a virtual sound source is located and, for a particular virtual sound source, applying a cross talk cancellation process to a sub-set of the loudspeakers, said sub-set being selected on the basis of the location of the virtual sound source in the defined space.
