SirenFX NoisePalette is a noise generator designed to produce signals with customizable spectral characteristics. It utilizes a high-quality spectral tilt filter to create noise with varying power spectra, enabling precise control over the tonal color of the noise. This approach allows users to shape the noise signal beyond standard types, offering a more natural and organic sound quality.

Different noise colors, such as white and pink noise, are commonly used in audio engineering for their consistent spectral roll-off, which mimics many natural phenomena. NoisePalette expands on this concept by allowing users to adjust the spectral roll-off continuously from red to violet noise, covering a range from -6 dB per octave to +6 dB per octave. This unique feature provides unparalleled flexibility in crafting noise textures that fit specific creative or production needs.

The noise generated by NoisePalette serves as a foundation for a wide variety of sound design applications. It can be processed through modulators, granular synthesizers, or other effects to create realistic ambiances like rain, wind, surf, or mechanical and environmental sounds such as vehicle cabin tones and gas leaks. Additionally, it can be blended with existing audio to enhance texture and presence, making it a powerful tool for sound designers and music producers seeking to enrich their sonic palette.
