Anvil

This is a synthetized sound of an anvil hit by an hammer. It has been created and recorded using the SuperCollider programming language (see code below).

It uses an exciter-resonator model.

## SUPERCOLLIDER CODE

// 1. evaluate the following code to define synths and resonator parameters
(
~frq = [600, 252, 312, 204];
~amp = [0.03, 0.43, 0.66, 0.5];
~dec = [0.86, 0.55, 0.4, 0.12];

~bus = Bus.audio(s, 1);

SynthDef(\exciter, {
|out=0|
var sig, env;
//env = EnvGen.kr(Env.perc(0, 0.01), doneAction:2);
//sig = LFNoise2.ar(10000)*env;
//sig = HPF.ar(sig, 400);
sig = Impulse.ar(0);
Out.ar(out, sig);
}).add;

SynthDef(\resonator, {
|
in=0, out=0,
frqScl=1,
frqOff=0
|
var sig, amp=0.21;
sig = Klank.ar(
`[
~frq,
~amp,
~dec
],
In.ar(in,1),
freqscale:frqScl,
freqoffset:frqOff
);
sig = Limiter.ar(sig, 0.9, 0.01);
//sig = FreeVerb.ar(sig, room:0.7)*amp;
DetectSilence.ar(sig, time:0.01, doneAction:2);
Out.ar(out, sig!2 );
}).add;
)

// 2. evaluate the following block of code to create the sound
(
~resonator = Synth(\resonator, [\in, ~bus, \frqScl, 10]);
~exciter = Synth(\exciter, [\out, ~bus]);
)
