This is a saturation VST plug-in made with Juce, usable in any DAW.

Here is a picture of the plug-in used in Ableton Live

How the plug-in works:

The sample $n$ of the output signal $out[n]$ is $f(in[n])$ with $in[n]$ the sample $n$ of the input signal and $f$ a waveshaping function which is a saturating function $f: x\mapsto -1$ if $x\leqslant -1, 1.5x-0.5x^{3}$ if $-1 \lt x \lt 1 ,1$ if $x \geqslant 1$.

Waveshaping function in red, with the $x\mapsto x$ function in blue for comparison

The definition of this function is done in DSP_functions.cpp.

Commands of the plug-in

The plug-in has two knobs:

• "Input gain", multiplies the input signal by a constant before applying the waveshaping function.
• "Dry/Wet", allows to blend the output signal of the plug-in (wet signal) with the untouched input signal (dry signal).

How to build the plug-in:

• Install the Juce Projucer
• Set up a default project for an audio plug-in
• Replace the source code from the default project with the source code from this repository
• Build the code to produce a VST3 plug-in
