[Acen]

The main difference between white and pink noise, is white noise has the same level of power across all frequencies. Whilst pink noise has the same level of power across an octave.

There are more frequencies in the high-range, so it naturally sounds considerably higher pitched.

i.e. a C6 on a keyboard sits at around 1Khz (1046.502 to be exact) and a C#6 is 1108.731 KHz (a difference of 62.229 Hz)

While a C3 is 130.8128, and C#3 is 138.5913 (a difference of only 7.7785 Hz).

Then using an entire octave as an example, C3 (130.8128) to C4 (261.6256) = 130.8128 (0Hz up to C3)

vs C6 (1046.502) to C7 (2093.005) = 1046.503 (0hz up to c6 +- 0.001hz)
