If one does have a generous HD capacity, it may be worth while copying all
of a large recording into a computer, providing what one looks for is easil=
y
recognisable on the computer screen.
Two species of cicadas, and two species of birds presently sing
intermittently in my garden. I was able to add an 80 GB HD to my Mac G3 fo=
r
a surprisingly small cost. With PEAK LE software I can easily see on the
spectrograph trace on the computer screen, when a cicada or bird was singin=
g
nearby. So ...
I can set my Tascam to record a 125 minute DAT while I do other things;
then set the G3 to copy the Tascam's digital signal, again doing other
things while that is done. Peak allows the Spectrograph trace to be
expanded or contracted at the click of a mouse, and to jump forward a scree=
n
at a time again with the click of a mouse. I can quickly scan the whole
recording in that way.
I note the time at the beginning and end of each period where nothing is
happening, and after I've thus gone through the whole recording, I can then
delete and replace with a second of silence, each period that I don't want.
This leaves me with the useful parts of the original 125 minutes, and the
facility, if I wish, to relate any part of it to the actual time when it
happened.
At that stage, assuming it's now down to less than 80 minutes, I can set th=
e
G3 to copy it to a CD if I don't want to work on it immediately, and when
that is done, delete it from the HD and reuse the 125 min. DAT.
I hope this is more help than nuisance.
