Pink noise is a type of signal generator module that produces a noise signal with equal energy per octave. Pink noise is used to add a sense of depth and warmth to a sound, and is commonly used as a source of background noise in music production and sound design.
Pink noise generators typically include a control for adjusting the overall level of the signal, as well as filtering options that allow users to adjust the spectral content of the noise signal. This filtering can be used to attenuate or boost specific frequency ranges within the pink noise signal, allowing for further customization of the sound.
Pink noise can be used in combination with other modules, such as filters, envelopes, and amplifiers, to create complex and dynamic sounds. By modulating the level or spectral content of the pink noise signal using CV signals from other modules, users can create evolving and unpredictable sounds that are not possible with traditional synthesis techniques.
