Until I read this , I hadn’t really thought about the randomness of pink noise but now I will have to find out more…

ACO Pacific – Extremely Random pink noise generator

“Many computer generated noise sources utilize 16 bit registers with 32 kHz sample rates. The resulting 2 second pseudo-random cycle has a limited bandwidth – typically 50 Hz to 16 kHz and the repeated 2 second “fold-over” of the registers produce a measurable “click” – a source of measurement error often requiring averaging 10’s or 100’s measurements. The 3025 has a useful bandwidth of 1.6 Hz to 39 kHz with 119 uHz line resolution.”

How random is software based pink noise generated in Smaart, Spectra Foo, etc…? What about hardware based pink noise generators?
