Default What is the "stereo angle'?

Quite often, when discussing a stereo mike setup, there is reference to the
stereo angle. Just what is the definition of the stereo angle, and how is
it defined mathematically?

Thanks,

Hey Norm...

This is off the top of my head and it's been a while since the 'books'
BUT I believe you may be looking at one of three numbers depending on
what question you are truly trying to answer...

so here are my takes....

1. stereo angle of a 'co-incident pair' of mics.... 90 degrees (mic
diaphrams nearly touching but perpendicular to eachother while
capsules remain on the same plane... you can find illustrations of
this online)

2. in an ORTF position... think like you're placing your microphones
like your ears work spaced about 8'' apart (17 cm??) and the stereo
angle is 110 degrees I believe... (look up ORTF I'm sure its on the
web)

and 3. (this has nothing to do with mic'ing... ) I suppose you could
be talking about proper stereo placement for nearfield monitors???
which generally speaking is a equilateral triangle with your HEAD
being the third 'point' of your triangle... (technically that would be
60 degree inner angles of a equilateral triangle)

hope this is what you were looking for... take care Norm.
