[sdiy] Cheap audio spectrum analyzer

[Jean-Pierre Desrochers]

Hi Ritchie,
Did you notice the price tag for these things ??
$1500 and more...

I was just thinking of a Raspberry PI DIY audio analyzer project
that could connect on a small VGA screen. Easy to put around my test 
equipments
taking lots of place so far ....
I'll do some looking on the web.
Thanks anyway.
