I=92m not terribly sure, either, Rob. When comparing data, though, I began =
recording with Sennheiser MKH30/40 MS combos in 1987, when I got the first =
beta DAT recorders from Sony to try. I was very careful to calibrate the in=
puts to known standards and put a tone on the front of each take to insure =
(as best I could) the integrity of the examples so that subsequent recordin=
g protocols could be matched. When I returned to sites to see if there had =
been any changes, I was also very careful to set up in the same places as I=
have in some over the course of 20+ years. That way, at least, the illusio=
n is somewhat consistent and a few inferences can be drawn if not sustained=
as being pretty good comparisons. We=92ll see how that thesis holds up to =
future investigation.
