Added in git a simple fractal noise generator implemented as a white
noise filtered by a cascade of 15 first-order filters (7 SOS and 1 FOS).
The code has been generated with Faust and manually adapted for Csound.
I have also added the original dsp file in Opcodes/tl/fractalnoise.dsp

Syntax

 ares fractalnoise kamp, kbeta

Performance

 kamp   --  amplitude
 kbeta  --  spectral parameter related to the fractal dimension
            0  white
            1  pink
            2  brown

Trivial example

 kbeta line 0, p3, 2
 seed  12345
 aout  fractalnoise 1500, kbeta

Warning: watch out for the level of the signal (grows with kbeta)
