Well, I think the MD recording of the Owl sounds much better than the
camera recording. The MD has better low-freq. and a "fuller" ambient sound.
I do not see excessive noise in either, though, and I think you are hoping
for sound that is cleaner than you can reasonably expect from
consumer-grade equipment and spontaneous field recordings. The gain of the
MiniDisc is far below that of the camera, but it's still getting a good
recording. I had to boost the MD signal by 18 dB or so to get them equal,
and still didn't create any excess noise in the MD recording.
On the Drongo, the recordings are just too different to compare. The MD
seems to be set way too low, or the mic is malfunctioning or the MD is
malfunctioning. I do see some 60-cycle hum in the Drongo MD recording. Is
that from an external source, or an indication of a bad connection in the
MD/Mic connector? Others' opinions?
