Transformation done for ASPMA (Audio Signal Processing for Music Applications), 2014. Originally that was a distorted guitar arpeggio loop (noisy and irregular), the goal was to "frequency stretch" the audio, trying to let it sound synthetic/electronic instead of bell-like in a aesthetical result that wouldn't resemble a guitar anymore.

That's using sms-tools HPS model on the 5s mono cut I've uploaded (remix from TwistedLemon guitar sound) with the parameters below.

Frequency scaling factors = [0,1,.3,1.7,.6,.2,.9,1.2,1.4,.9,1.8,2,2,.7,3,1.7,4,.5,5,3]
Frequency stretching factors = [0,1,.3,.7,.6,2,.9,.8,1.4,1.7,1.8,.8,2,1,3,1.7,4,1,5,.7]
Timbre preservation = 0
Time scaling factors = [0,0,5,5]
