Best EQ VST Plugins
Get Started

Before we get deeper into this, let’s say a few things about equalizers...

Although once they used to be bulky and heavy pieces of equipment, equalizers are now accessible as VST plugins.

This has not only made them easier to handle, but they feature more possibilities for demanding productions.

Equalizing is an art, and once you master it, your tracks will become more lively, sweet, and even punchy and moving, if that is what you are looking for.

Frankly speaking, EQs can be the difference between a bland and a rousing track.

But to master the art, you need to have the right tools. That’s why here you will find 13 different recommendations to choose from!

Let’s start!

The 13 Best EQ VST Plugins of 2021 include:

1. Fabfilter Pro-Q3

4. Wavesfactory Spectre

Wavesfactory Spectre

For starters, Spectre by Wavesfactory brings a little twist to the world of equalization.

Unlike other alternatives that employ typical phase manipulation to boost tones, it leverages on harmonic saturation.

Ideally, it only works to boost, hence will not work for contouring the frequency spectrum.

On the contrary, if you want to advance the body and presence to a tone range, it definitely fits the bill.

Graphical Display

What’s more?

It blends the best features of an enhancer alongside graphical parametric EQ.

That way, it can process the difference between the input signal and the EQ signal.

Consequently, it can work on lone tracks, sub-mixes, or entire mixes with desirable efficiency.

Are you looking for versatility?


You’ll appreciate the multi-band enhancing feature and up to ten saturation algorithms.

Filter Controls

It can introduce harmonic content unavailable in the original recording, thereby giving it color and life something impossible via conventional means.

In the end, you can forget about dull recordings and step into a new world of colorful natural sound.

A reliable pick when it comes to matters timbre shaping, it works based on a simple concept of identifying the basic pitch of an instrument.

In application, as the pitch changes with the note getting played, this plugin provides the option of adjusting selected corner frequency in line with the shift.

That is to say, as the note moves, the frequency band of interest plays along.

Surfer EQ 2

We are diving a little deeper.

It uses synthesizer filters which track the pitch of a monophonic vocal source to keep the timbre of a tone all through the instrument’s voices all in real-time.

Moreover, SurfererEQ 2 has up to seven bands, which can be set to track the vocal source and adjust its frequency accordingly.

7 Bands

Notably, the tool’s pitch can be managed via MIDI notes, essentially allowing EQ bands to get played via a keyboard.
