Description

Rainbow is a frequency domain processing effect. It splits its input into frequency bins, and operates on these. Besides spectral dynamics processing, it has a range of 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.

Some of the features are:

- Frequency domain compression/expansion

- Spectral gating

- Linear phase EQ + brickwall filters

- Threshold frequency response (Tilt and Curve)

- Frequency display with gain and frequency grid zoom

- Resizable window display
