Saturator Plugins, Guitar Amp [VST, AU, AAX]DAW music production AAX, AudioUnit, and VST saturator plugins that produce non-linear saturation and overdrive effects, including mixing console, tape, and valve saturation, guitar amp and guitar cabinet overdrive sound. Saturation is an effect which is created when sound becomes louder than a certain threshold level, the loudness cannot raise anymore and thus saturation happens. Saturation effect produces harmonics, with pure sinusoidal tones becoming harmonic-rich square wave tones. The type (even, odd) and balance of created harmonics depends on the saturation algorithm, the simplest of which is called clipping (which removes a signal above the threshold level in a "hard" way).
