things I learned from this article:

1. black noise exists
2. black noise models the frequency of natural disasters

welp, didn't want to sleep tonight anyway

The sense of sweeping pitch is created by clocking the "noise function" (usually lfsr) faster or slower. If the noise pattern is very short it will sound like a pitched instrument, otherwise it will just sound like crispy noise at diff. pitches.

There must be an arduino proj that just does noise like this. Not really sure what op is wanting tho eg. hardware or software.

I thought the minute you tune white noise it ceases to be white noise. Pink or brown?

pink and brown noise are specific types of noise relating to different mathematical functions, iirc.

I was thinking about abstract categories. Your implication is false, there are objects which aren't random but without period neither, see for example geometric progression. But there is no random object with period. You have to notice/assume something more to put an equivalence to these statements. Perhaps you was talking about common general rule, where I could agree.

Computer's inability to be random you have stated isn't an immanent property.

That's all semantics, the sentence is correct either way. Get over it. :3

For eurorack zorlon cannon and maybe hex invertors Jupiter Storm

Reading the description of the sounds from that link something like the hertz donut mk2 would work as well, seems like the big thing it's doing is fming rather than filtering

YMCK's magical 8bit plug may be able to do it as well.

If you mean modular as in analog modular synth, you could buy a Zorlon Cannon. Or build something on your own. From a quick google, say this or this:

Just add a voltage controllable squarewave generator.

lol....right.

Noise spectrum changer, more like?

I can imagine using a serial eeprom with 2kbits of storage and a pic chip of sorts to have it spit out your 4-bit+ sample. Cheap as all hell, but may require some work and programming on your end. Once you got that worked out, you could then feed it into your tuner as posted above.

(...) because it is theoretically infinite.

That's why I've marked I was talking (writing) about abstract categories.

Right! But you've chosen a bit different property, the inability to be random is a nonimmanent consequence of it (and some other properties). I agree about practical details you have mentioned.
