WebMar 4, 2024 · Pink noise is filtered white noise. 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. WebMethod: (1) generate vector x(t) of white noise samples; (2) FFT it to produce X(f) (actually, this is unnecessary, since transformed white noise is white in frequency, too); (3) multiply by the filter H(f) to obtain Y(f); (4) inverse FFT to obtain y (t).
