Rich and others,
I've never used a reflector before, as I'm mostly interested in stereo
environments. I read Klaus' paper describing the use of two pzms in a
parabola. What kind of stereo image can be achieved with a parabola and
a pair of more standard mics? Any field reports? Recommendations? Ideas
to try? Ideas to avoid?
