As a basic recipe for generating noises with arbitrary spectra,
one would: take a piece of white noise -> Fourier-transform it ->
multiply by a suitable kernel -> inverse-transform back to the
time domain.

As to the implementation, you might have a look at Artlandia
( Particularly, see examples at

1/f noise (also called NaturalArray) is used quite extensively
in the package (albeit for the artistic purposes which might
not be want you want :-).

Hope this helps.
