Crosstalk cancellation is a well-known technique to deliver virtual 3D sound to a listener via two or more loudspeakers. In this method, the binaural source signals are processed with a network of prefilters prior to loudspeaker reproduction in order to ensure that only the prescribed source signals reach the corresponding ears of the listener, such that all acoustic crosstalk is cancelled out and no significant reverberation is present. Since listeners might slightly move their heads within a certain range while listening, robust designs are needed. In this paper, we propose a method for the robust design of crosstalk cancellers in which we replace known least-squares techniques by a p-norm optimization that allows us to explicitly control the amount of crosstalk and shape the remaining reverberation effects according to a desired decay.
