this is planned but will happen after the rest is
in place.
assuming it is dolby prologic encoded 2ch
audio.
thus
C=L+R
LFE=ignore or LPF 100Hz C (not sure the correct
value)
LS=RS=L-R or perhaps LS=L-R, RS=R-L with perhaps a
30ms delay.
otherwise there will be a problem playing out 2ch
on a 6ch audio out system (you would only get L and R with sound)
cheers

Comment (by Mark Spieth):
added 14 which fixes
- ac3 audio
amplitude levels are now invariant (encode/decode produces
same
levels)
- only allow 2 and 6 channel modes
- if 6 channel on decode
and want 2 then use DOLBY surround encoding
- decode to and encode from
L,R,LS,RS,C,LFE format

could your work be used to convert 2 channel dolby surround
into a 5.1 signal?
