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)
