Fork Code: UI sounds (pt1)

name

code content

// UI sounds
// this code is an attempt to recreate a sound
// inspired from some technological/electrical UI interface

// 1. first define the synth
// Here we are using the FM technique
(

	fc=1000,

	var modulator = SinOsc.ar(fm);
	var carrier = SinOsc.ar(fc + (idx*modulator) );
	var sig = carrier *  env * amp;
	sig = HPF.ar(sig, 1000);
	Out.ar(0, sig!2);
}).add;

// 2. then define the Pbind which will play the sequence
// of UI sounds simulating variuos characters showing up on an
// imaginary display.
// Play around FC, FM, ATK and RLS to obtain different sound characters.
