Re: Code for generating 1/f^alpha pink noise

Thanks for all the input.

I haven't compared this method to the Voss-McCartney method.  In my 
application I required 1/alpha^(5/3) noise, which cannot be generated by 
the Voss-McCartney algorithm (or at least I couldn't figure out how to 
modify it in such a way).

I haven't compared the AR and MA methods either.  I'm no DSP expert and 
once I had a working filter that produced good enough results I went 
back to my original project.  :)  In fact, I decided to use only a 
two-pole filter in my application since I didn't want the values 
deviating from zero for long periods of time.

Anyway, I hope the code is useful to others as well.
