Hi!
I understand! And I understand the "fatigue" of "parabol sound" after
such a trip.
I would never say that the Stereo DATmic has the same "clarity" as
the MKH. It has though, the best "clarity" at 90 degrees out from
each mic, depending on the PZM effect. That is, 90 degrees towards
the plate. As a matter of facts, one could even claim a "sharpness"
of tone from the sides. You can hear it when saying a sharp "ssssss"
straight into the plate, about a foot from it.
Using the Stereo DATmic to get stereo recordings of birds in front of
it is the "worst case" scenario. The PZM effect is low + that the
highest frequencies get out of phase with one-another, hitting the
membranes from the side.
Right now I don't have a sound card. As soon as I get one, I will
comment on your recordings.
Best wishes,
Klas.
