Hi Sami--

Welcome. Interesting project! One thought others may be able to
substantiate or refute. One can encounter peculiar distortions when
recording very hi Hz sources with DAT and MD.  I've encountered this
numerous times when close micing field crickets and grasshoppers with
flat response mics. The result sounds as if two or more frequencies
are beating against each other making lower Hz pops and other
artifacts. I'd consider renting a good mic, an MD recorder and a good
reel to reel recorder for a day and run some tests.  A used, reel to
reel Nagra might be fairly affordable. Record at the fastest speed,
15 ips.  The Jukebox 3  is Mp3 right?.. This seems least likely.  Rob
