In the new system LRL is computed with interpolation, just as LRR
for cs = 0 to 15
LRL = ((sra(lr) + (sra(lr)-GS(lr))*(15-cs)/15) +
sri(-cs))*tvcorr(|lr|+|cs|);
for cs = 15 to 22.5
LRL = (sra(lr) + sri(-cs))*tvcorr(|lr|+|cs|);
Rear outputs during steering from Left Rear to Full Rear
As the steering goes from left rear to full rear the elements follow the ones given in the
AES paper, with the addition of the corrections for rear loudness.
For cs > 22.5, lr < 22.5
LRL = (sra(lr) + sri(cs) + rboost(cs))
LRR = -srac(lr) + sric(cs_bounded)
This completes the LRL and LRR matrix elements during left steering. The values for
right steering can be found by swapping left and right in the definitions.
Center matrix elements
The center matrix elements in v1.11 have major differences with the center elements in
the July 1996 patent application. The ’89 patent and pro logic have the following matrix
elements.
For front steering
CL = 1 + .41*G(cs) - G(lr)
CR = 1 + .41*G(cs)
For rear steering
CL = 1 - G(lr)
CR = 1
