It's around two years that i looking for precursors on seismic signal
speeded up by wave conversions.
I use the SOX converter. 
It's able to convert binary files to waw in many ways and made also
changes on loudness of the file as a volume control.
It's a wonderful experiment, i planning to translate one my web page
in english but due to the time i don't did so at moment.
If you want to see the italian page you could visit this page:
There an interesting correlation on precursors signal recorded in 8000
times speeded up seismic signals and ELF recorded by elfrad group.
And other interesting things like the ability to recognize doppler effect
on trucks passing near the station.
