Hi, Dumb as I am, I have a question about retrieving random stuff out off radio hiss:
If it is/could be possible with FM hiss, is it possible too with a recording of, for example, a leeking faucet, tree-hiss forced by the wind, a sack of beads falling to te ground, even the sound of a shower, etc.? And
I don't see why not. If you got a high enough sampling rate (44khz should do nicely), and set a peek threshold so anything under a certian volume was a 0 and every peek over was a 1 I could think of a BUNCH of samples that with a little playing with the threshold could produce some pretty random resluts. Furthermore, by adjusting the threshhold you would get a toatly different number. Using a random sampling with a random threshhold would bring you closer to a truely random number. Of corse it's still not possible to get a truely random number because you gotta get the threshold value somehow... see below for why...
what is, by the way, TRULY randomness - could that ever be reached? I have a bold assumption: it never can be.
That was my understanding, but I'm no expert on the subject.
Housenumbers aren't good for that - that *I* know.
Absolutely, because the seed is not truely random. For instance, most random number generators use the current time from the internal clock to generate a random number. However if you were to do the exact same thing at the exact same time (down to the millisecond) it would reproduce the same number. If you try this let me know what you find!
