Dan,
I have more on another paper below but what I have also found is:
"Choosing and Configuring a Stereo Microphone Technique Based on
Localisation Curves
Magdalena Plewa1 / Piotr Kleczkowski1"

Spin down past the maths and look at the plots on page 9. These give the
object/image localisations for various setups. Figs 6 and 7 compare ORTF
with XY at 90 deg.

John,
I've just waded through this paper and it is assessing distance perception=
with different loudspeaker combinations in large auditoriums.
They settled on an ORTF mic setup:
"In a comparison of various stereophonic
microphone arrays, Hugonnet and Jouhaneau [8] find
that coincident techniques (such as XY and MS) yield
the most accurate lateral localization, while closely
spaced techniques (including O.R.T.F.) yield the finest
distance discrimination. In another comparison, Ceoen
[9] found a subjective preference."
The recordings were all done on an ORTF mic rig, after rejecting AB and MS=
but "dipole" loudspeakers were included in antiphase. They were only lookin=
g
for distance and special effects, not lateral effects.
However, one reference looks interesting but I haven't located it:
C. Hugonnet and J. Jouhaneau, =E2=80=9CComparative
spatial transfer function of six different
stereophonic systems,=E2=80=9D 82nd Audio Eng. Soc.
Conv., London, Preprint 2465(H-5), 1987.
My conclusion for nature recording? Check out your rigs with a shaking
peanuts test using your ears. :-)
