Saturation Reverser

Saturation Reverser is an educational plugin.

Features

• Demonstrates that a specific distortion, typically considered to be irreversible, can be reversed.
• This only works to reverse tanh distortion when exactly level matched, it is NOT a restoration tool.
• The left side of the plugin is a tanh saturation with variable gain boost.
• The right side is an atanh reverse saturation with variable attenuation.
• Completely open source.

Background

This plugin was released for demonstration purposes only, specifically to show that saturation type distortion still preserves detail whereas clipping results in information loss. You can try it out yourself. The saturation feature is also perfectly useful on its own, especially if your DAW has plugin chain oversampling, like REAPER does.

The reverser feature is useful only as a kind of fun trick / demonstration and has limited utility in music production outside of perhaps producing experimental weird crackling distortion.

Please do not misunderstand the point of this plugin and think it magically is supposed to reverse all distortion. It doesn't. There were some user reports that they were able to use it to help restore previously distorted material, and if you use it to good effect, then sure go for it. But the plugin was never intended for actual restoration work, it was just meant to be a demonstration of mapping to tanh, and back using atanh.
