Eric,
By definition, a 5.0 or 5.1 array needs five discrete sources, normally
mixed down from many sources on a mixer. The ".1" is bass mixed from the 5=
channels sent to a single non-directional woofer.
I listened to the Cingo demo and it is a professional mixdown from the usua=
l
multiple studio music sources to stereo. They do clever things with phase t=

produce an expanded sound using headphones, but I can't see how a similar
result could be got from a single outdoor mic rig.
Cingo seems to be aimed at the playback market and the codec would not be
aimed at the individual user. As far as I can see, you take a multiple
sources mixdown to stereo (2.0) and play it on a Cingo enabled hardware
device.
As for 5.0 or 5.1, in practice you can't derive five sources using a single=
mic position unless it is a narrow angle gun mic array and that gives
multiple other problems. Multiple cardioids will give you shared signals
from single discrete sources. A cardioid pair is effectively two (combined)=
omnis and two fig-8's which will collect sounds from 360 degrees but from
only two directions on the fig-8's at best, giving three channels with many=
shared sounds between them to mix.
