This is my first disquiet junto project.

I recovered an old recording of my 3-year-old son singing an improvised song in an invented language. Then I reversed it. All the sounds are modulations of speed, pitch and/or amplitude of the recording.

The original (reversed) recording can be heard at the beginning and end of this piece.

Moorings (disquiet0160 - Oneminutepastmidnight)

Here's the Supercollider code that I used to generate this track:

// original sound "https://soundcloud.com/roger-pibernat/moorings-disquiet0160-oneminutepastmidnight"
// the oblique strategy used was "Change time"

s.boot;

(
SynthDef(\oblicardo, {|bufnum|
	var sig, delay, amp, env, timer, envtrig, right, left;
	sig = PlayBuf.ar(
		2,
		bufnum,
		LFPulse.kr(2).range(
			LFPulse.kr(0.5).range(1,2),
			LFPulse.kr(1).range(4,8)
		)
		, loop:1);
	amp = (Amplitude.ar(sig) > 0.01);
	env = EnvGen.kr(Env.perc(releaseTime: 1), amp);
	delay = sig * env;
	delay = CombC.ar(sig, 1, LFPulse.kr(2).range(0.05, 0.1), 3);
	right = RLPF.ar(sig, 1200, SinOsc.kr(0.1).range(1, 0.02));
	left = delay;
	Out.ar([0,1], Splay.ar([right, left], SinOsc.kr([0.1,-0.11])))
}).add;

SynthDef(\disk, {|bufnum|
	DiskOut.ar(bufnum, In.ar(0,2));
}).add;
)

// sound file
b = Buffer.read(s, "your-path-to-the-file.wav");
// output file
c = Buffer.alloc(s, 65536, 2);

c.write("your-path-to-the-file.aiff".standardizePath, "aiff", "int16", 0,0,true);

(
fork{
	x = Synth(\oblicardo, [bufnum:b]);
	d = Synth.tail(nil, \disk, [bufnum:c]);
	60.wait;
	d.free;
	x.free;
	c.close;
	c.free;
};

Oblicardo [disquiet0171-oblicardo]

A MicroBrute synth connected in feedback-loop through a loop pedal set to 3-seconds with a slight fade out.

Three layers were recorded.  Each one is a single note sustained throughout the loop.  One of them (lower) is a triangle wave with the LFO modulating its frequency, and the other two are square waves with the LFO modulating the pulse width.  

Each layer is a loop that is permanently recording the output of the synth and feeding it back into it 3 seconds later, where it mixes with the sustained note creating textures and patterns by cancelling some parts of the wave and clipping others.  The result of this mix gets out of the synth and back into the loop pedal where it gets recorded and fed back into the synth once again, starting the process all over and creating the evolving sound.
