This noise is extremely nice and I would like to use it as a Ugen. I believe I have to copy this page into Extensions, but what else? Thanks.

```
(
// probably more useful as a pseudo-ugen
FractalNoise {
*ar { arg beta = 0, mul = 1, add = 0;
var n = 6, h = 2, fp = 50, t = SampleDur.ir, norm = exp(beta).reciprocal**1.72, sig = WhiteNoise.ar(mul,add);
n do: {
var fo = 10**(0.5*beta*h.reciprocal)*fp;
sig = FOS.ar(sig,1,exp(-2pi*fo*t).neg,exp(-2pi*fp*t));
fp = 10**h.reciprocal*fp
};
^(norm*sig)
}
}
)
```
