Dear Dan and Klas,
other than using pocket recorders for nature recordings, either
short recordings on selected subjects or long unattended recordings for
soundscapes. I also use autonomous recorders for long term soundscape
recording. As I use several recorders in different places, then the main
problem is analyzing them or at least getting a picture of their contents.
For this purpose I use my own software to produce compact spectrograms
showing a whole day. I like to record 10 minutes every 30 minutes, 24/24h,
to get 48 frames/day. In this web page (
http://www.unipv.it/cibra/cibra_sabiod.html - I'ìm sorry it is in italian),
you can see my "compact spectrograms". I use them to have a global picture
of what I recorded, I can then focus on days with clenaest and richest
recordings, discover recognizable and recurrent sound patterns, and also
discover unusual sound patterns. By using these spectrograms I can also
compare sites with different soundscapes, e.g. with different sound
diversity and sound richness, or with different levels of anthropogenic
noise. To speed up analysis, I can easily recognize and skip silent days or
rainy days and focus only on the best recordings. I use these images as an
index of my recordings and then I focus with higher resolution spectrograms
on specifc patterns and events, down to few seconds spectrograms to
recognize species or events. The freeware version of my software does not
includes this option yet, but I'm planning to release it soon.
If interested, in the following paper you can find the same compact
spectrograms with an overview of the research project behind them:
https://www.researchgate.net/publication/284164121
I'm also searching for other software to make easier the organization,
cataloguing, and analysis of huge amount of files at different time scales,
e.g. from seconds to hours and to days. Do you have any hint ?
Thanks for all the valuable infos and thoughts I get form your posts, and
ciao to all my friends on the list

Hey everyone,
just on a note of spectrograms. I recently discovered that my favourite
free audio software “SoX” can do spectrograms too (amongst thousands
of other things): http://sox.sourceforge.net/
And since it is terminal/bash based, you can script it for batch
processing too.
Here are some example spectrograms I have generated with it yesterday:

It has limitations and the documentation is in French but I use free program
Acousmographe to create spectrograms. Very powerful and the spectrograms may be
annotated. It generates Flash animations. To create videos I import the Flash
files into Adobe Premiere, a video editing program, and output as MP4.
