CODA Labs – Szechuan Saturator

 

 

Szechaun Saturator’s design is based on the McDonald’s Szechaun Sauce. It’s design alone should make it one of the best free saturation plugins! Coda labs have taken the idea of a ‘secret sauce’ and applied it to saturation. The plugin will fit neatly in your DAW to give you “sexy harmonics that will fill a hole in your life”.

The saturation algorithm offers a range of saturation modes and has been designed to modulate the saturation function continously as the input signal changes. This can create heavy distortions or subtle warmth to your tracks. The modulation rates can also be adjusted to provide tremelo effects to your input signal. The vst also includes subtle compression that will be applied to your processed audio. Perfect for the drum buss, guitars or synth.

As well as providing saturation, CHOW Tape Model also emulates the degrading of analog tape. This is great when used with the plugin’s high pass filter and wow & flutter settings to create old “vintage” tape cassette effects.

Initially the plugin was built for a Music 420 class at Stanford University. Chowdhury has made the source code availble via github, if you’re interested in audio programming or DSP check it out.

Roxolder – Tomato Preamp

 

Tomato Preamp reproduces a vacuum tube preamp with a two triode vacuum tube that will saturate and overdrive your audio. Tomato is the sort of plugin can easily dirty up your clean signals by introducing a lo-fi charcter to them. 

It features 3 distinct tube models, New, Aged & Fresh. Each of these has its own flavour of saturation, ranging from subtle warmth to a more distorted sound.

One limitation of the plugin is that there is no control over the saturation. The developer suggests including an equalizer in the effects chain to help shape the plugins timbre.

Sleepy Cat Audio – Crush

 

 

Crush has a slightly different layout for a saturation effect, but don’t let that fool you, this plugin can give you some intresting results.

Crush’s unique saturation models crossover distortion common in the analogue hardware class-b tube amplifiers. This emulation produces a very unique, crunchy sound which can be controlled using the alias and bias functions. 

The developer notes that if the plugin receives an impossibly high bias value, due to the way the crossover distortion was modelled, the alogrithm produces distortion similar to a 12-AX7 preamplifier tube. 

Check it out, this is one of the best free saturation vst plugins offering crossover distortion.

Shattered Glass Audio SGA1566

 

 

Audio SGA1566 is an amazing emulation of a single channel, two stage vintage tube mic preamplifier. It creates a very good recreation of the analog sound through real-time high-performance circuit simulation.  The plugin also has two-band active Baxandall EQ which can be placed either before or after the preamp. This really helps you to sculpt the character of your saturation.

If SGA1566 requires too much DAW processing power you can change the cpu performance modes, not that the low CPU mode drops sound quality.

SGA1566 has a great saturation algorithm that offers to add authentic tube saturation sound or analog warmth to your signal.

Softube Saturation Knob

 

 

Saturation Knob is the best free saturation plugin from Softube. This is one of my favourite plugins! It’s a simple one knob plugin for adding colour and analog warmth. 

The modeled output distortion has three different saturation settings, high, neutral and low, which allow you to prioritise the frequency bands you want to saturate. 

It’s a fairly low CPU hit too which means you can put it on quite a few channels. I use it quite a lot on vocals and think it is one of the best vocal saturation plugins. This is well worth getting!
