Hello,

i experienced this kind of analysis from since April 1999.
I used SOX to convert binary raw data in WAV files.
You can find a special web page at:

http://www.infoeq.it/doc12_e.htm


I and Andrea Cellini coined the term "phonoseismology"
and we published an article on an Italian scientific magazine sometimes ago
about it.

The pourpose was to catch out precursors signals.
Something happened, try to listen the quakes on my web site.

The ideas of Arie to use stereo channel for two different station
located let's say 10km away could VERY interesting to locatethe source of an
event.
I suspected that when i started to use sound analysis as precursor research
method.
Unfortunately i have no possibility to monitor two identical station so far.
I would strongly encourage each of you to do something in this direction i
firmly
believe will bring interesting results.

My compliments to Arie!

Cheers
Mauro
