Incandescent Rainbow

Rainbow is a frequency domain processing effect. It splits its input into frequency bins, and operates on these. Besides spectral dynamics processing, it has multiple frequency domain effects, and features 2 linear phase EQs, one applied to the dynamics processing Source and one to the Output.
It covers a range of applications, including spectral compression and expansion, parametric equalization, broadband noise reduction, sidechain ducking,
pitch shifting, and sound design with its various spectral effects.
