Raw sounds were generated by manually fiddling with audio cables, field recording, and tone generators. I fed them all into Audacity and layered and blasted them out in different ways - pitch shifts, overdriving, intentional clipping and phasing, cutting off the tops and bottoms of waveforms, running them through tweaked reverbs and sound reproducers designed for slowing down music - intentionally misusing effects to create new sounds and distortions. Once I had a big project file going, I split it up into sections and started arranging things to create patterns, rhythms, and repeating themes, and work the noise into a kind of narrative that was forming in my brain.
I've always liked this sort of thing. Would love to know how you did it
