MEqualizer by Melda Production (Windows and Mac)

If you are new to mixing it can sometimes be of help to have an equalizer that gives you a visual representation to the changes you make in sound. MEqualizer by Melda Production comes in handy here. First of all it is a very well sounding free VST equalizer. It has six bands to tweak and for each band you can choose between 7 filter types.

MEqualizer can be used in a more clean mode but it also allows you to dial in tube saturation and harmonics to your taste through which it will function more as a vintage or analog sounding equalizer.

It comes with a spectrum analyzer and a sonogram and even has an auto-listening option which enables you to zoom in on a certain band. To top it all off you can use it in several modes including mid or side mode and of course in left + right mode for normal use on stereo or mono tracks.

MEqualizer even has it own limiter build in. A very versatile equalizer indeed.

MEqualizer comes as a part of the MfreeEffectsBundle that includes several other nice free VST plugins.

SlickEQ by VOS TDR (Windows and Mac)

SlickEQ is one of the best free VST equalizers out there. It has three bands plus a high pass filter.

While the mid band is a bell curve you get the choice between shelf and bell filter for the low and high band.

You also have the choise of four different filter curve slopes: British, American, German, and Soviet – inspired by hardware consoles from the respective countries (at least the first three).

SlickEQ is very smooth. You can push it pretty far in the high frequency area without any harshness.

Should you desire a subtle saturation you can dial that in by pressing the EQSat button and choose your calibration type in the outstage section where you also get to choose whether you want automatic gain ajustment or not.

SlickEQ can function either as a stereo or mono equalizer or you can use it in either mid or side mode. You can chain two instances of the SlickEQ and thereby double the amount of bands to tweak or set one in mid and the other in side mode and thereby having a very nice m/s eq.

This free VST EQ plugin is highly recommended and should you desire extra options the commercial Gentlemen’s Edition is very affordable.

SonEQ by Sonimus (Windows and Mac)

SonEQ is again one of those very nice free VST tools for digital audio work. You can control the input and output which gives you control over to what extend the eq should work with a clean or vintage sound. The harder you push it the more saturation you get – just like with an old analog mixing desk.

SonEQ has a both a high and a low pass filter. It enables you to do the ”Pultec Buttom End Trick” by boosting and cutting the same freqency in the low band area at the same time.

The mid band can be adjusted to a target frequency between 150 – 4000 Hz and gives you a choice between two q-settings.

The high band can control the frequency spectrum from a center point of either 6, 8, 12, or 15 Khz. For extra saturation use the drive section. A very nice free VST colouring eq!

RED EQ by Acustica Audio (Windows and Mac)

Red EQ by Acustica Audio is a simple yet very well sounding free VST equalizer. Acustica Audio use a form of convolution technique to “sample” the sound of hardware devices. Through this they are attempting to create plugins that are as close as possible to hardware in sound and function. Whether they are more successful in this attempt than developers that base their plugins on algorithms is a question of debate on many internet forums. What can be said here is that their RED EQ is a very good equalizer and definitely worth having in your tool box. It has three bands: low, mid, and high. While the mid band is a bell curve the low and the high bands are shelf EQs.

OCHRE EQ by Acustica Audio (Windows and Mac)

Ochre is another fine free VST EQ from Acustica Audio. It gives you three bands to play with: a low bandwhere you can choose between a centre frequency from 35 – 315 Hz, a mid band with a choice of centre freqency from 315 – 2.500 Hz, and finally a high band where you can chose a centre freqency between 2.500 and 22.000 Hz. Each band can be boosted or cut by up to 16 dB, and you can choose a Q between 0.5 and 4.0. Ochre also has a pre-amp stage that can be switched on for more “analog colour” or off for a cleaner sound. There is also an input gain control as well as an output gain control. Since the plugin acts much like a hardware device you can use these controls to feed the right amount of level to the plugin – and you can “drive” the input to get more colour. Like RED EQ from the same developer Ochre EQ maintains a sweet sound when you boost the high band.

Luftikus by lkjb (Windows and Mac)

Luftikus by lkjb is a very nice free VST EQ that works very much like the Maag EQ 4. It has six fixed bands: 10 Hz, 40 Hz, 160 Hz, 640 Hz, 2.5 kHz, and a high boost band / high shelf where you can choose between five different beginning points in the freqency spectrum (2.5, 5, 10, 20, and 40 kHz). Luftikus has an analog switch that will give you a little extra analog grit and colour. You can use Luftikus in normal mode ot you can switch on the mastering mode that will give you a stepped functionality for the first five frequency bands which comes in handy for mastering tasks. There is a trim for the output volume, or you can turn on the “keep gain” function so you won’t be fooled by differences in loudness when you tweak the equalizer. This is a high quality free VST EQ plugin and it is a valuable tool both for mixing and for mastering purposes.

ColourEQ by DDMF (Windows and Mac)

ColourEQ by DDMF is a very clean free VST eq. The name simply refers to the fact that you can choose between different colours for the GUI. It comes with five bands of \”super parametric\” peaking filters, which means that there is one more parameter in addition to the traditional gain/width/frequency set that can influence the curve shape.
