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 <https://www.nps.gov/subjects/s=
ound/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.
