We did use all analog-- the zener (or a transistor E-B junction reverse
biased) generates the noise. 7 cents, no programming, and very low
power consumption.


But you'll need more than a simple RC filter to mimic 3dB/octave.
First order filters give 6dB/o

The filter can be passive but it needs about as many parts as the number
of octaves.
