Also, I have no idea how to check the distribution. It sounds the same as uniform noise and looks the same in the spectrograph? What gives? Do I need to average over a very long time or something to see any difference?
It should sound the same and look the same spectrally. There was a previous discussion on the list about how noise distributions (uniform vs gaussian pdfs) should sound. Namely, the same :)
To see the difference, you could try to calculate kurtosis values! I've never had a good use for that one. http://en.wikipedia.org/wiki/Kurtosis That statistic will show you the difference between Gaussian and uniformly distributed noise, and confirm your distribution.
The Box Muller method should be good--that's a very reliable method.
