Saturate is a simple saturation plugin.
It is not aimed to replicate the saturation of a particular device, it just makes a saturation in the strict sense of the term.
The plugin processes the waveform to make the saturation effect, by cutting the waveform as soon as the level exceeds a threshold value. The output gain is then automatically adjusted to correct the loss of global level. For a better quality, an oversampling of x4 is used for the processing. A gain knob is provided to adjust the output gain.
This example shows different levels of saturation. The first waveform is the original waveform, the plugin has been used for the second with a moderate ratio of saturation, and the third with a high ratio of saturation.
