[Csnd] Noise Signals and their Random Distribution

	Hi list, I have a question for the theorists here: if I have two different noise signals, both having the same random distribution, shouldn't they sound the same? I'm asking because I tried recreating a certain type of noise by determining its histogram, turning that into a GEN40 and then using cuserrnd to create a different signal with the same distribution. The two didn't sound alike at all, unfortunately... I assume my theory is wrong?

	They will not sound the same unless they are generated using the same seed. There is noise at slower lower frequencies also.

	Ah. That would explain why the major differences were in the lower frequency bands... Thank you! And it sounded like such a good idea :( Oh well, I guess I'll have to find a different way.
