5+ Best Vari Mu Compressor Plugins in 2023

Looking for some good Vari Mu compressor plugins? Your long wait is over because we have done a lowdown on some of the best Variable MU compressor VST plugins for you to choose from.

A Vari-Mu or variable-gain compressor is an analog compressor that is centered around a vacuum tube. 

With an increase in the input signal, the current sent to the tube’s grid decreases, which sets into motion reduction in the output level of the compressed sound.

So, are you ready to find the best variable Mu compressor VST plugins? Without further ado, let’s get started.

5+ Best Vari Mu Compressor Plugins 2023

1) Royal Compressor

Emulating a model of the classic British Royal Compressor from the Beatles era, Royal Compressor delivers a true analog compressed sound with warm saturation and subtle compression.

You can dial lush and warm compressed sound as heard on the records from the 1960’s classic rock era.

This nifty Vari Mu compressor simulates vari-mu circuits that can come in handy for audio material that runs the gamut from drums, vocals, to bass guitar, and bus channels.

What’s more, you can customize the amount of valve saturation and output 64-bit audio at a high internal sample rate without overclocking the CPU.

2) FireChild

Featuring up to 4 models of the Variable-Mu Compressor that run the gamut from transparent version to Tube Versions (A/B/C), FireChild accurately samples and emulates vintage compressor units of the 1950s.

These vintage unit emulations deploy vacuum tubes for reducing gain in the audio signal path without relying on re-routing to a compression circuit.

You can dial in the compression on the 3 Tube models A/B/C at the input stage and use Bias control to trigger Tube Saturation and add distinct coloration to your instrument tracks or mix.

FireChild offers up to 8x oversampling and over 6 Release modes, where each mode is intricately sampled from 4 different units with variable tubes at different stages of tube life. 

Further, you can make use of a Knee control parameter to shape the contours of compression.

All in all, FireChild is one of the best vari mu compressor plugins that can be used by both professional and beginner producers.
