If you're looking for a free saturation plugin to add warmth and character to your audio, TubeSat v1.0.0 VST3 Beta is an interesting option to try.
TubeSat is a VST3 plugin designed to deliver analog-style saturation through asymmetric saturation and harmonic wave-shaping. It can be used for a variety of mixing applications, from drums and bass to vocals and mix buses.
One of the main concepts behind TubeSat is its asymmetric saturation core. This processing generates additional harmonic content that can add body, density, and warmth to an audio signal. It can be used subtly to add a touch of analog-style color, or pushed harder for a thicker and more aggressive saturation effect.
