Best EQ Plugin Reviews

Music creation is a complex process, and in the past, you had to use many hardware instruments, music mastering tools, units, etc. But now, thanks to computers and modern technologies, all these tools are available on almost any device. Such software, as equalizers, is important for making your music more lively, juicier, and deeper; that’s why you need the best EQ plugins. At first, they were developed after an analog EQ plugin by completely copying its functionality, and in time more and more features and possibilities were added. Now, the EQ VST can contain so many features that even after using it for a year you wouldn’t know about all of them. Next, we will review EQ plugins in more detail.

FabFilter Pro-Q 3
Best EQ plugin
With FabFilter Pro-Q 3, you get the highest possible sound quality, a very extensive feature set, and a gorgeous, innovative interface with unrivalled ease of use.

EQ plugin types: digital and analog

Equalizers can be divided into 2 groups, digital and analog. Digital EQ plugins are the most common nowadays because they are much more comfortable and efficient for us. In these equalizers, you can find a frequency spectrum, change a frequency, and start carving away. With user-friendly interfaces, pleasant graphics, and accuracy of a computer, they are a must-have for high-quality music mastering. The only disadvantage here is that they don’t have that analog sound vibe.

On the other hand, analog equalizers are predecessors of digital ones. Therefore, they are used only by old-school music producers. They are not as accurate and flexible as digital plugins, but they have that warmth, character, and musicality. So, thanks to technological progress, you can utilize these old analog equalizers by using plugins that emulate analog equalizers.

Ozone features vintage modules that faithfully recreate the sonic characteristics of classic analog hardware. These modules offer unique ways to enhance your mixes with a vintage touch.

Vintage tape

The Vintage Tape module in iZotope Ozone 10 Advanced adds warmth, subtle distortion, and saturation reminiscent of analog tape machines. As an author, I find that using the Vintage Tape module adds a pleasant vintage flavor to my mixes, making them sound more organic and inviting.

To use the Vintage Tape module effectively, you can adjust the input and output levels to match the desired loudness.

Examples of how to apply the Vintage Tape module include using it on drum tracks to add warmth and subtle compression, applying it to vocals to give them a vintage character, or using it on a full mix to add a cohesive analog feel.

Vintage limiter

The Vintage Limiter module in Ozone 10 Advanced plugin replicates the behavior of classic hardware limiters, providing transparent peak limiting with a touch of vintage character. I appreciate the Vintage Limiter for its ability to control the dynamic range of my mix while adding a subtle analog flavor.

Functionally, the Vintage Limiter offers controls for adjusting input and output levels, as well as the release time. By setting the input level, you can determine the amount of limiting applied.

When using the Vintage EQ, gentle boosts or cuts can be applied to shape the frequency response. Experimenting with different vintage EQ models, such as Pultec-style or Neve-style EQs, allows you to achieve different tonal characteristics. For instance, you can use a Pultec-style EQ to add weight to the low end and smooth out the high frequencies or employ a Neve-style EQ for precise and focused tonal shaping.

Vintage compressor

The Vintage Compressor module in iZotope Ozone 10 Advanced emulates the behavior of classic analog compressors. Using the Vintage Compressor, I've found it effective in smoothing out peaks, adding sustain, and providing cohesiveness to individual elements of my mix.

The Vintage Compressor offers features such as threshold, ratio, attack, and release controls. Adjusting the threshold sets the level at which compression is applied, while the ratio determines the amount of gain reduction. By manipulating the attack and release settings, you can shape the compression envelope to suit your desired sound.
