Colored Noise Generator

SirenFX NoisePalette is a versatile noise generator, capable of generating signals with variable power spectra using a high quality spectral tilt filter.

It is customary to assign colours to different noise spectra, such as the “white” and “pink” noises audio engineers are so familiar with. These noise signals have a constant spectral roll-off, often found in many natural processes. Therefore, they sound more natural than noises shaped with more classical filter designs.

NoisePalette is unique because it allows you to dial in the precise spectral roll-off, from red (-6 dB/Oct) to violet (+6 dB/Oct). The generated noise signal can then form the basis for a wide range of useful sound effects, by sending it through a modulator, granular synthesizer, or any other processor. Such effects range from room tones of vehicle cabin interiors, natural ambiances such as rain, wind, and surf, or the high-frequency sounds of gas leaking and fizzing. Alternatively, the noise signal can be mixed into existing sound assets to thicken or give them more presence.
