Conventional finite impulse response (FIR) filters are not ver efficient for providing the low- frequency boost required for efficient cross-talk cancellation over a wide frequency range. Warped FIR (WFIR) filters are better suited for the task since they have better resolution at low frequencies. An implementation of a cross-talk cancellation network for the stereo dipole demonstrates the advantage of using warped filters.
