So is 'brown' noise. So white noise is your raw lumber before painting. There was a "digital random" chip 30 years back. I used it a lot. But the repeat was very audible, every few seconds a thump. The consistent dynamics and non-tone sound made it good for level line-up and also spectrum analysis.
