| 1. A method of audio processing, comprising:
(a) separating left and right input signals into low frequency bands and high frequency bands;
(b) applying cross-talk cancellation to said low frequency bands to have left and right cross-talk cancelled outputs; and
(c) combining said left high frequency band with said left cross-talk cancelled output, and combining said right high frequency
band with said right cross-talk cancelled output;
(d) wherein a cutoff frequency for said low frequency bands is determined by a peak in the frequency dependence of an inverse
matrix of head-related transfer functions.
