I have found this:
1/f noise can be created using random noise generators but it can also be
producted using deterministic functions. One such method is a finite
difference equation proposed by I. Procaccia and H. Schuster

Hi Jim:
Music synthesizers now use sounds recorded from real instruments and play them back. Why not record a real heart beat,
maybe different ones from children, men, women, etc.?
Have Fun,

I think a simple table approach sounds like the quick / dirty way to go.

Hi
I was going to suggest picking start and stop points in the table with your
random number generator, but it's pretty much the same thing.
If the base rate is 60 bpm, then each spacing is 16.666… ms. My *guess* would
be that anything past 0.1 ms likely doesn't matter for the base rate. If th

Ok, how about a nice simple table? Something in the 500 to 4K entries
shouldn't repeat often enough to be noticeable. Each entry probably can be a
byte.

Yes.. that might work..
Or, for that matter, I believe you could do it by randomly selecti

I need to generate a sequence of pulses at around 1 Hz with a 1/f
characteristic (human heartbeat, as it happens). I'd like to do this
using software and a timer, so I'm looking for a clever algorithm using
a random number generator to do it.
I could take the phase noise spectrum and turn th
