What is audio saturation, and what are the best saturation plugins? This Icon Picks roundup features 20 saturation effects that will harmonically enhance your music.

Fabfilter Saturn 2 - Best Saturation Plugins

What is Saturation in Music?

Audio saturation is an effect that generates harmonics and applies soft-clipping compression. Saturation is also the essence of what makes analog hardware sound musical and pleasing. Driving sounds through tape, tubes, transistors, and circuits have long been an essential ingredient in great-sounding mixes.

The effect originates from the analog days when audio recordings ran through various pieces of hardware. Mix engineers discovered they could overload magnetic tape machines, tube amps, and transistor-based preamps to create saturation and “soft-clipping” effects. This technique gave recordings sought-after qualities that improved the sound of mixes.

Artists and engineers use harmonic generation to add presence, character, warmth, edge, cohesion, and more to digital audio. From subtle to extreme, saturation is an integral part of amazing mixes.

The Different Types of Audio Saturation

While studios still have analog equipment, the music industry has mostly shifted to the digital realm. Plugin emulations provide the same great sound as their hardware counterparts without the maintenance hassle and high price tag.

Here are the three main types of saturation plugins that emulate the imperfections of analog hardware.

  • Tape Saturation: Tape saturation plugins emulate the sound of audio recorded through analog tape machines.
  • Tube Saturation: Tube saturation plugins emulate the sound of audio driven through tube amps.
  • Transistor Saturation: Transistor saturation plugins emulate the sound of audio driven through transistor‑based circuits.

If your music sounds thin, weak, and digital-sounding, apply saturation to make it sound full, fat, and present. Analog emulation is one of the best ways to bring your digital audio alive!

20 Best saturation Plugins

Here are the 20 best saturation plugins for music production, mixing, and mastering. Any of them will make a great addition to your music toolbox.
