sorry for being unclear, i was joking with words...
what i'm looking for is exactly the behaviour i get from a stereo
correlation meter (or the W-X one for that matter), where negative means
out-of-phase, zero means mono and positive means stereo'ish.
my intent is to be able to tell at a glance whether a signal has lots of
X, Y, or Z information. for instance, i would expect the Y and Z meters
to linger around 0 for an open-air recording of a single musician at the
same elevation as the microphone. Z would move to 1 when a plane flies
overhead (or a subway rumbles below), and Y would indicate sounds coming
from off the median plane.

Kurt is up in Heaven now.
can i humbly request configurable correlation
meters for the next
release? it would be really useful to have one for each W/X, W/Y and W/Z
(for "forwardness", "rightness" and "upness" :)
I don't think it would work as you expect. Correlation is not the
right thing to find directions, as it is completely independent
of the relative levels. For example, a single source at 85 degrees
left sitll indicates +1 for W/X correlation. You'd probably expect
a large negative 'rightness' and something like 0.1 'forwardness',
but that would need a different kind of meter.
