Hi,
I made two generators for Gaussian white noise, one using DSP, the other as message based version. Both use the same algorithm, but the histogram analysis of both shows a defect with the message version: The histogram has a visible "valley" around the central expectation value, so it doesn't look like a real gaussian bell curve anymore.
The message version is based on [random] not [noise~], and I "faked" a true frand by taking and scaling random values from the range 0-100000. Could this be the reason for the valleys or is the reason the custom algorithm [random] uses or is it, that two [random]s are not sufficiently independent?
Ciao
