With this software, you can achieve an effect when the analog recording device or medium (such as a preamp or a tape machine) is driven too loud so that the sound it produces starts to break up. These distortions are pleasing to the human ear and will add a punchy character to pristine digital recordings.

You’ve come to the right place if you need more context regarding this sound effect. First, I will explain what saturation is and break down its common types. Moreover, in case you do not know where to start and how to pick the saturation plugin that will satisfy your needs, I’ve created a list of optimal saturation software components after carefully analyzing the market.

What is audio saturation?

In the world of music, saturation is a mix of distortion and compression that occurs due to overloading the recording device or other physical components of an electrical system.

Even though there are different flavors of saturation depending on the machine the sound is driven through, this effect generates harmonics and brings subtle forms of soft-clipping compression. Thanks to this, the sound becomes louder, punchier, and fuller. You can also expect saturation to add presence, warmth, and depth to the mix.

Types of saturation

Depending on the machine used for analog saturation, this effect can sound different and add various shades to your mixes. So, let’s take a look at the most common saturation types.

Tape saturation

If you’ve been hunting for warmth in the saturated sound, it will be good to know that you can extract it from tape saturation. When the voltage level exceeds the tape’s ability to record it, tape saturation happens.

Tape saturation plugins emulate the sound put through tape machines. They generate punchy distortion and harmonics by applying a controllable overdrive, so you will achieve harmonic distortion that will add dimension, fatness, and depth to your mix.

You can slap tape saturation on any instrument, but it will shine on lower-frequency ones like drums and bass.

Tube saturation

When evoking a classic sound in recordings is your goal, you should consider tube saturation plugins. These software components emulate the sound driven through tube amps when the electrons can no longer flow from the tube’s cathode to the anode because of the positive charge created between the two.

Tube saturation provides the sound complexity our ears crave for. It enriches the plain sound with warmth and gives it a visceral, raw vibe. As you can balance the drive and output, you gain control over the level of distortion. However, saturation can have an aggressive edge when you push too hard.

Transistor saturation

Transistor saturation happens when the sound goes through transistor‑based circuits, and the current attains the highest specified value. This causes the sound to become brighter and more defined with mid to high harmonics.

The sound distortion achieved from the transistor easily cuts through other musical instruments. You can expect a fuller, more complex sound from this effect. The mix with transistor saturation becomes fuzzy, gritty, and textured.

Soundtoys Decapitator – best overall

Soundtoys Decapitator

Would you like to get a secret saturation weapon for your arsenal? You will never go wrong by picking a Decapitator analog saturation modeler from the Soundtoys brand for this mission. This plugin is a good choice for adding character to all kinds of instruments in your mixes.

Add analog saturation to your digital studio to be able to beef up your mixes and unlock new dimensions of plain sounds. Before building this saturation emulator, Soundtoys tracked the dynamics of vintage gear to deliver precise effect reproduction.

Whether you want to add a subtle or extreme distortion to your mix, the Decapitator will ensure you get the saturation range that will smoothly suit your needs. To achieve this, there are five different saturation modes that will give the edge to bass, spice up your guitars and vocals, or give more expression to drums. In case you want to add pure brutality, just hit the Punish button and see how your mix gets new shades.

With the modeled tone control, you can shape the saturated sound to ensure it gets the desired dimension. Use a mix control feature to incorporate dry signal for parallel processing without routing and sub-mixes.
A Soundtoys Decapitator plugin is flexible and user-friendly. However, it is not compatible with 32-bit systems, so you can’t use it on older computers.

Regarding sound quality, I want to admit that this plugin can give hot competition to an analog hardware piece. It’s great for warming up bass, enriching melodic components, and giving cohesion and shine to a mix. From subtle saturation to punishing deliverance, this plugin enables it all.

With five different sound profiles that give amazingly different results and an option to configure saturation level, the Soundtoys Decapitator plugin is the only one you will need to spark up your mixes. Because of this and the high sound effect quality, I regard this software component as the best saturator plugin.

Waves J37 Tape – budget pick

Waves J37 Tape

Meet Waves J37 Tape, a tape saturation emulator with a solid vintage character and good delay effect implementation. It was created in cooperation with Abbey Road Studios as a prototype of physical machines used to create the most fabulous samples of modern music.

This saturation VST has a variety of adjustable controls like Tape Speed, Bias, Noise, Saturation, Wow and Flutter, and Waves to recreate the original machine’s sonic character and give you the effects for fascinating and ear-pleasing mixes.

The J37 by Waves has three tape formulas, but the difference between them is very subtle. In fact, this makes this plugin an effective instrument for tone connoisseurs rather than rookies looking for simple sounds.

The delay section is one of the most valuable parts of J37. It offers a wide palette of sonic expressions, from gentle saturation to wild delay effects. This allows you to create a variety of mixes.

Waves J37 Tape has a nice tone, regardless of what tape formula you select. It does an amazing job of reshaping the sound you put through it and making it sound firmer. However, I noticed that sometimes it could be too hard in the upper-midrange. In general, it’s very sensitive, so if you push a little bit too hard, you will get an effect that will irritate your ears.

When you are looking for a budget saturation plugin that will let you emulate 60s-flavored mixes, Waves J37 Tape is the right choice for you. It will give your tracks an authentic tape hiss by neatly replicating the effect of the original machine.

You can expect smooth parameter transitions with adjustable knobs, MIDI sources, and Smart Parameter Interpolation. Besides, keeping track of what is going on while you mix is easy due to the traditional frequency analyzer with low frequencies on the left and higher frequencies on the right.

The saturation in FabFilter Saturn 2 is great. The plugin has four tube settings that allow you to add new shades to your musical creations. Using them separately will give you just a perfect amount of enhancement. However, the Broken extreme setting will enable you to achieve a full-on metal-style distortion. After all, as there are controllers, you can always choose how extreme or warm you want saturation to be.

Generally, FabFilter Saturn 2 is much more than just a saturation plugin. It allows you to emulate a wide range of effects for bright and juicy mixes. You will have all you need to nudge your creativity with elaborate controls and several saturation settings.

Klanghelm IVGI – best free saturation plugin

Klanghelm IVGI

With a free Klanghelm IVGI plugin, you can spice up tracks with a wide range of saturation effects. Even though it is a light version of the SDRR saturation plugin, it can still deliver smooth and warm saturation along with dense and dirty distortion that breaks through the noise of other instruments. It makes it the best free saturation plugin out there.

The IVGI plugin features a simplified control scheme compared to the paid version, but the analog saturation algorithms are as good as in SDRR. However, it is more like a soft saturation device, which will work both on individual channels and in the stereo bus.

There are four knobs you can use to configure the character and transparency of saturation you apply to the sound. For example, you can use the Drive knob to adjust the amount of saturation. The Asym Mix control lets you fine-tune the symmetry without disrupting harmonic distortion. Finally, with the X-Talk control, you will simulate crosstalk on a stereo signal.

Klanghelm IVGI reacts dynamically to the input signals, so you can easily configure saturation to make it sound amazing in your mix. I will say that saturation is gentle and warm, but when you want to go fancy, you can set extreme settings and extract the desired sound effect.

Saturation Knob has three switchable modes, which allow you to select the source material and the desired effect. By setting Keep Low, you concentrate distortion on the mids and highs without interference with the lows. In a Neutral setting, you engage the whole frequency spectrum. Finally, in the Keep High position, you keep the high-end relatively clean while focusing saturation on the lows and mids.

It works great and sounds amazing, no matter the saturation range. This plugin can smash a drum loop or add harmonics to vocals or other instruments. So, by offering to select the saturation spectrum from subtle to extreme, you can make your mix sound more definite and crisp.
