Thanks, Klas. This looks like a good organization system. I=92m looking for=
a way to produce sonograms of long files (like two hours) to file with the=
audio as visually-scannable images. The National Park Service does it as s=
hown in miniature on this page:
https://www.nps.gov/subjects/sound/data.htm
Where each stripe is a two-hour sonogram. The software that produces the 24=
-hour sonogram uses 1/3-octave data recorded by a sound level meter. In ord=
er to display a recording it would be necessary to make a real-time analysi=
s pass through the recording first, or make a simultaneous analysis on loca=
tion.

Hi Dan,
for sonograms and editing I use a very old version of Audicity. Nagra SD
gives me 60 min files and Olympus and Sony 3h 23m files. It takes about
a minute to open such a long file. You can save it as a .aud project.
No, I don=B4t save the sonograms. If I use Audicity to make any kind of
filtering or EQ however, I save a screen dump of the settings. A cut
will be named after what happens, or the bird, animal or event + the
original file name and stored with the original file in a folder named
after year, equipment used and place. I often take a picture of the
equipment used and add a text file into the folder with the same name as
the folder or "lead words". Writing .txt in the search function makes
the search much faster. For documentary purposes, for what it is worth,
I save at least 10-15 full days from every year.
Was that an answer?
Klas.

Dear Klas, you wrote,
Making SoundScapes is different. Then I place a mic and a recorder out
somewhere, often at a place that I am familiar with from before, and
leave it till the next day or longer. Coming back, I replace the battery
and the card and start recording again. Since many years, I have one
test site where a stereo mic and recorder is out 24/7 from February to
the end of June. It=B4s a 2-3 hours job to sonogram and listen to the
files, but also very relaxing and rewarding.
What software do you use to make sonograms of your long files? Do you keep =
the sonograms as indexes to the audio files?
