MPolySaturator is a spectral saturation plugin designed to enrich audio signals by generating harmonics for every individual frequency component. Unlike traditional saturation effects that often introduce unwanted distortion when processing complex sounds, this plugin enhances richness without adding harsh artifacts. It achieves a clean harmonic enhancement that preserves the integrity of intricate audio material, making it suitable for a wide range of signal types.

The core innovation of MPolySaturator lies in its ability to produce precise harmonics without the typical dissonance caused by standard saturation methods. While conventional saturation works well with simple tones like sine waves, it often degrades complex signals by generating discordant noise. This plugin addresses that challenge by creating harmonics that complement the original sound, avoiding the usual dirt and preserving clarity. Users can also modulate harmonic levels dynamically, adding movement and interest to the sound by assigning modulators that respond to input levels or random variations.

MPolySaturator includes advanced features such as mid/side and surround processing, extensive modulation options, and a highly customizable user interface with GPU acceleration for smooth visual feedback. It supports multiple channel modes and offers smart randomization, automatic gain compensation, and safety limiting to ensure optimal performance. Compatible with major plugin formats on both Windows and Mac platforms, it provides a streamlined workflow with global preset management and free lifetime updates, making it a powerful tool for enhancing audio with clean, controlled saturation.
