# How to reproduce this sound?

Hi everyone!
I’m wondering how to produce something similar to the stuttering sound in very high frequencies, from 25’25" to 26’30" in this beautiful piece by Kassel Jaeger (aka François Bonnet):

https://kasseljaeger.bandcamp.com/album/meith

I thought of static noise filtered with just the high frequencies, but the result is very different…
Any idea?

Hi,

Maybe this is a starting point?

``````SynthDef(\pling, {
var freq = \freq.kr();
var sig = (SinOsc.ar(freq) * SinOsc.ar(Rand(10,30)) * 0.2) + SinOsc.ar(freq * {Rand(2.91,3.02)}!2);
var env = EnvGen.ar(Env.perc(\att.kr(0.01), \rel.kr(0.3)), doneAction: 2);
sig = sig * env * \amp.kr(0.1);
Out.ar(0, sig ! 2)

Pbind(
\instrument, \pling,
\dur, Pwhite(0.003,0.05),
\freq, Pwhite(3785,3800),
\amp, Pwhite(0.01,0.1),
\att, Pwhite(0.001,0.01),
\rel, Pwhite(0.02, 0.1)
).play

Here’s another attempt:

``````(
s.waitForBoot({
SynthDef(\plong, {
| out=0, amp=0.1, freq=2700 |
var sig1 = HPF.ar(amp * Convolution.ar(Saw.ar(freq), Dust.ar(100)), 10000);
var sig2 = HPF.ar(amp * Convolution.ar(Saw.ar(freq), Dust.ar(100)), 10000);
Out.ar(out, [sig1, sig2])

s.sync;

Synth(\plong);
});
)

Thank you guys, you are awesome! Very good starting points! The one suggested by @shiihs sounds very close to the original.

Not perfect, but a nice sound:

``````(
{
var trig = Dust.kr(25);
var sound = DynKlank.ar(`[(1..5)*2700, TRand.kr(0.025,0.04,trig!5), 0.1!5], Trig.ar(trig, 1/SampleRate.ir), 1, 0, 1);
sound = sound + (BrownNoise.ar(0.075)*Trig.kr(trig, TRand.kr(0.01,0.03,trig).poll));
sound = LPF.ar(HPF.ar(sound, TRand.kr(6000, 7500, trig).lag(0.01)), TRand.kr(4000, 5500, trig).lag(0.01));
Pan2.ar(sound, TRand.kr(-0.5, 0.5, trig).lag(0.01))
}.play
)

Thank you @Sam_Pluta for introducing me the object `DynKlank`, very interesting!
