Interesting thread! IIRC the Paul stretch plugin works it's magic through a FFT analysis which demands some processing power. One thing that comes to mind is CSound. It's a free, text based audio generation and manipulation program. It has a large suit of FFT functions that may interest you. The "pvsblur"-opcode is particularly interesting. Wouldn't know how to emulate the sound of FFT time stretch with pedals though :0:0:0
Thanks man--looks cool! Somewhere in the back of my mind I had a thought about track and hold in connection with the sound I'm digging for - - based on a demo of the Doepfer A-148 or A-152 or somesuch. I remember drooling about the Spectra Mirror when it first came out--seems like some real possibilities there....

Yes! Thanks, that is definitely on point. I've probably watched the demo for the Audio Damage Spectre 6900 times with exactly this sound in mind. The FFT is the sound/texture for sure.... The only challenge is getting it to conform to pitch content, I think. I mean, mixing it in with guitar tone could be cool, but probs ultimately unsatisfying because like jam slathered on toast rather than pure jam. I wonder if fully wet FFTed signal can be made to respond to cv @ 1 v/octave? Or maybe I'm just having my usual comprehension difficulties....

This reverb from D Rainger seems relevant to my instant paulstretch junky interests (talking to myself haha )
Doubling back to this mildly moldy thread to drop this vid, which brings to light all of the in the Mystic Circuits Spectra Mirror so perspicaciously pointed out by lordgalvar (thanks again lg!)

So sad that it is already discontinued
RIP, purple knobbed beauty

Dandolin, have you tried running the carrier out from an MF-102* into the tracking input on the old Boss RPS-10?
I think Spectra Mirror is back too. I should finish soldering the last three parts on mine someday.
*Maybe a v/OCT LFO/OSC (dixie, richter oscs, etc.) would work as a tracker? I'm kind of thinking an LFO following the same relative intervals as the main oscillator, just several octaves down, could be interesting. I haven't tried it. I'd think it would take some tuning to get it right...but just turning the knob on the MF-102 resulted in pretty quick shifts of pitch, I just don't know how accurate it is at the extremes.
The RPS tracks into just popping about the last third of the knob turn toward the slow end of the carrier osc. Like 0.6hz to the 10s of hz somewheres.

I have a pretty good idea about making something seem timestretched, you can try it out with basically any multifx
stereo delay dry/wet type or panning 100% wet =>
stereo panning tremolo max depth=>
mix the two signals down to mono.
play with very fast settings, as long as the delaytime is not synchronized with the tremolo time you get sounds like time stretch

I feel like I should be able to get this sort of sound from my Pladask Fabrikat. Gotta give it a whirl.

You guys rule! Putting my Fabrikat funds aside; I'ma try the wet panning delay trem technique and MF-102 carrier out into RPS Maybe both at once
I do think high frequency modulation of variably filtered copies of a signal is promising. I just got in the Boredbrain Transmutron thingie. I might try putting various combinations of Bitrman, full wet resonant delays, tracking-mode Superego, super-resonant settings on the Ghost Fax, noisy Generation Loss, Outward/Bakvendt, Syntax Error, some ring mod, etc. in there and rev up the morph between the loops to see what happens. World's weirdest rotary speaker sim?
loving what I'm hearing from Form/Fabrikat! Thanks for sharing that....
