hi, i just have read a text about residualism , or the possibilities of some digital tools about exploring the non-audible part of sound: "sound is never described in what is absent, missing or overlooked: negative space...most of the digital detritus gets noise reduced, multi-band compressed, brickwall filtered out...but we now find ourselves immersed in the next wave of digital audio...new tools have emerged that are capable of exploring both the signal and what's behind it..."
do anybody have tried that in pd? which options do i have to explore this?
many thanks
