Claim 9:
10. The method of claim 1, further comprising:
generating headtracking data;
computing, based on the headtracking data, a front delay, a first front set of filter parameters, a second front set of filter parameters, a rear delay, a first rear set of filter parameters, and a second rear set of filter parameters;
for a front binaural signal that includes a first channel signal and a second channel signal:
generating a first modified channel signal by applying the front delay and the first front set of filter parameters to the first channel signal;
generating a second modified channel signal by applying the second front set of filter parameters to the second channel signal;

for a rear binaural signal that includes a third channel signal and a fourth channel signal:
generating a third modified channel signal by applying the second rear set of filter parameters to the third channel signal;
generating a fourth modified channel signal by applying the rear delay and the first rear set of filter parameters to the fourth channel signal;

outputting, from a first front loudspeaker, the first modified channel signal;
outputting, from a second front loudspeaker, the second modified channel signal;
outputting, from a first rear loudspeaker, the third modified channel signal; and
outputting, from a second rear loudspeaker, the fourth modified channel signal.
