Hi Ernst--
Yes, and some recordists prefer coincident stereo arrays. I'm curious
myself if someone feels that the arrays in particular pocket
recorders perform better, especially in natural locations. The
techniques I consider for distant subjects and ambience are quite
different from those I consider for close subjects.
A few recordists are adding a high density foam baffle between the
proximate capsules for additional separation and more lateral spread.
Opposing omni's, though not ideal, could be more effective towards
this goal than cardioids in X-Y or cardioids separated a couple of
inches and directed forward. Of course, its challenging to jointly
analyze stereo imaging performance because our monitoring systems
differ as well. Its probably tougher yet for subtle differences in
pocket recorder stereo imaging.
Extending Oryoki's analogy that pocket recorders are very well-suited
for taking the audio equivalent of "snap shots," one might note that
there aren't quality, wide angle lenses on entry level cameras. For
striking imagery with distant subjects, I'd certainly rely on an
external mic array. Rob D.
