Has anybody had any experience using PD to interface radio waves directly?
Broadcasting using sound cards... receiving using TV cards with FM tuners, that sort of thing...
Short wave or wi-fi radio spectrum analysis. What hardware have you used?
Here's quite an article: http://www.domenech.org/homebrew-sdr/1-e.htm
Just curious,

Interesting.
I have a wintv card with an integrated fm tuner, and I use it with a Linux sound input driver for alsa, so it should be compatible with pd. There's a command line utilitity to tune the radio stations, which is easy to interface with the shell object.
It doesn't work as expected...
Here's the list of alsa devices installed on my computer:
$ pd -alsa -listdev input devices:
output devices:
API number 1
So I tried to add the tv card as a supplementary input: $ pd -alsa -audioindev 1,3 -audiooutdev 1 But then pd complained: alsa: only one input and output device allowed (extras ignored)
If I use only the tv card for input, without output, it works: $ pd -alsa -audioindev 3 -nodac
Is there a way to use a non-symetric mixture of sound inputs and outputs? Using jack, maybe?
