Ah yes, I suspected something like this. Are they placed on the small
wooden boundaries like Curt's rigs? Absolutely this placement does
affect the performance and they way the test movies are interpreted.
The AT4002 omni should respond better to such boundary arrangement,
spatially, and this accounts for the left of center imaging for some
of the effects I selected (audible i the last segment). The boundary
placement should not affect the diffuse, distant voices passing
through walls.
I should have suggested positioning the mics in the open, right next
to each other so they receive the same input. The boundary use
shouldn't affect the self-noise evaluation though, our primary
curiosity. Rob D.
