Beh, you get a stereo pair for normal stareo content, a center
channel for movie dialog, a surround pair for ambience and effects
and a sub for earthquakes. And then some people claimed than you
could use Ls + L resp, R + Rs as stereo pairs for 'surround music'.
Questionable but it has been done. You can use a fairly standard
8-group mixer to create 5.1 content, mapping your intentions to
method is straightforward and not really ambiguous.
 
This doesn not really scale to Aura-3d or 22.2, unless you'd
think that umpteen stereo pairs, some of them vertical, are a
practical approach to creating a surround mix.
