#InfinitePiChallenge

Dear Supercollider Community,

I have been sonifying in python in my spare time some mathematical concepts mainly using Sagemath for doing the math calculations, writing to midi with python and creating mp3 with fluidsynth for example.

One year ago, I stumbled upon some formulas for calculationg pi and was asking myself, if it is possible to use these formulas in a sonification process, maybe with supercollider?

I have done a first step in this direction and sonified two or three formulas in python.

Here is my latest piece for supercollider, where I used some midi as input to supercollider, which I would consider a little bit as cheating, but not so much, since the midi was generated from one formula in python.

The source code and midi can be found here:

SynthDef(\kick, {
    |out = 0, pan = 0, amp = 0.3|
    var body, bodyFreq, bodyAmp;
    var pop, popFreq, popAmp;
    var click, clickAmp;
    var snd;

    // body starts midrange, quickly drops down to low freqs, and trails off
    bodyFreq = EnvGen.ar(Env([261, 120, 51], [0.035, 0.08], curve: \exp));
    bodyAmp = EnvGen.ar(Env.linen(0.005, 0.1, 0.3), doneAction: 2);
    body = SinOsc.ar(bodyFreq) * bodyAmp;
    // pop sweeps over the midrange
    popFreq = XLine.kr(750, 261, 0.02);
    popAmp = EnvGen.ar(Env.linen(0.001, 0.02, 0.001)) * 0.15;
    pop = SinOsc.ar(popFreq) * popAmp;
    // click is spectrally rich, covering the high-freq range
    // you can use Formant, FM, noise, whatever

I was asking myself, if someone of this community would like to step in and take the challenge to sonify one of the formlas purely in supercollider.

Thanks for reading.
