What's interesting is that with the RTL-U and r820t tunner, these guy are using java script in a browser to control the freq settings of the sdr and getting the audio out. Then also making spectrum to display in the browser also. no more c,python, just easier javascript with a good html interface.
Or, make your own....
I've just been getting into some basic SDR tinkering with a r820t RTL-SDR dongle. My interest was piqued by the recent ISEE-3 recovery effort and it's impressive use of SDR.
