[sdiy] Digital noise generation

[mark verbos]

I think the point of gaussian noise, or any specific distribution,  is 
to tune the probability of certain voltages in control applications, 
particularly in a Sample & Hold. When using noise as an audio source 
simply pink, white and red are good enough. Am I wrong?

In  the Buchla Source of Uncertainty modules, Don has simply +3, flat 
and -3 for the audio noise and several specific distributions in the 
stored voltage sections.
