Noise type

Pink Noise

How Soundwell generates pink noise and shapes it with Brightness and Resonance.

Definition#

Pink noise is a random signal with equal power in each octave. Its power decreases as frequency rises.

An octave spans a doubling of frequency, such as 100 to 200 Hz or 200 to 400 Hz.

How Soundwell generates it#

Soundwell uses a pink-noise generator when Color is set to Pink. The generated signal passes through a low-pass filter.

Brightness sets the filter's cutoff frequency. Resonance emphasizes frequencies near that cutoff.

Output requirements#

Pink noise does not require stereo channel separation. It works through headphones or speakers.

The connected output's frequency range affects which parts of the noise spectrum it can reproduce.
