Hi, I have just, completed an upgrade to the program "SdrDrum". It now can generate
audio (.wav) files with the ".GIF",  heiplot image. If the user so requests.
If you are interested please read the upgraded instructions and the program
can be found at: 

(Click "Download PSN related Software" at the bottom of the page)

There is an amazing richness in sounds, from a thunder of a quake to the
pop of the seismic waves bouncing from the core. The magnetic field has
sounds resembling bird calls.

Cheers

Arie

PS: read the instructions first.
