I still have not used the Marantz devices. However, I'm sure that there
is no reason to believe that the specifications on their web site were
wrong. Especially the new announced PMD 670 seems to be a good choice.
These solid state recorders and also the new hard disk recorders should
have no major problems with high humidity conditions, which has been a
serious problem with DAT recorders.
Compression algorithms as ATRAC or MP3 do not necessarily prevent the use
of such recorders for animal sound recordings. It depends on the type of
the sounds and on the kind of analysis that is carried out on these
recordings. Some of the introduced artifacts will be similar to the
reverberation effects caused by the environment. I recently made some
tests with quite demanding artificial signals. After reducing the large
bandwidth of the test signals (down to 8.5 kHz), the artifacts were less
dramatic:
