Gidday all,
at this link you can find an example of how Puredata software can be used with a RTL-SDR usb.

Could be useful for those doing radio astronomy and other things?
I hope to try and use it for Meteor passive radar using multiple usb SDR's.
The software is very graphical and has many examples. Can do audio, graphical, and video things.
kind regards, Alan Watson
