What I'm listening to today: "Strega processing LF radio signals", Tom Zicarelli
"Software Defined Radio" is a technique where an untuned radio receiver shovels the bottom 48 kilohertz of the spectrum into a computer's audio-in "raw", at which point bandpass/demodulation are performed in software. In this video an iPad runs SDR with intentionally incorrect demodulation/frequency settings, so the only output is chaotic squealing that a Strega smears into audio ambience.
