This spooky sound was created in Ableton Live using a variety of processing. The main device responsible is Pluggo’s Feedback Network. I ran a modulated synth pad into it, then removed all of the dry signal after automating several parameters. I re-sampled the results then pitched it all down two octaves being careful to filter out inaudible low frequencies. Finally, over the top I added a ping pong delay so the audio swirls around the stereo spectrum adding to the disturbing qualities of the sound.
