Hi Curt-
Can folks email me their votes and I'll tally up that data too? I
have 3; if can get another 7, that would provide some statistical
base.
I'm still mulling over my assignments. I'm trying to listen for the
percentage of "swishing" without being influenced by the changes in
tonal response. I think I can set aside two of the samples as
probably boundary mics, but that's not the primary curiosity/goal of
the test. The differences in the 5 ft and 10 ft samples is also
pretty interesting. Rob D.
