Pink noise, or 1/Æ, (one over frequency) is a low frequency wave-like pattern with equal energy in all octaves. a chart! (Yes that explains everything I'm sure.) Pink noise straddles the line between white noise and brown noise. White noise is entirely uncorrelated data, complete chaos, the snow on the tv screen.
