Best Free Vocal Saturation Plugins in 2024

In this article, we’ll read about the best free vocal saturation plugins that will ad analog saturation to your vocal in the mix.

Saturation plugins are very useful for both vocal mixing and overall mastering. These plugins add some harmonics to excite the dynamics of the spectrum.

So the resultant sound will be more clear crispy and have a vintage tape recorder feel.

We know that digital and analog recording differs in many ways.

The waves formed in the analog recording are pure sine waves that retain the original property of the wave but in the digital recording, you have to rely on off-bit and on-bit as the whole digital world consists of 0 and 1.

So what’s the heck?

Using saturation plugins. Especially in vocals.

These types of plugins recreate the original property of the sound waves. Below we’ll discuss some of the best free saturation plugins for vocals and mastering.
