What is Dynamic EQ and how to use it

dynamic eq

Dynamic EQ is a sound tool for designing a frequency range in combination with a dynamic range, There are several advantages to using dynamic EQ that will be detailed below, but the main advantage is the ability to make partial changes without harming the original sound.

What is dynamic EQ, and how does it work?

Dynamic EQ is a regular EQ except that apart from bands with the possibility of increasing a specific range in terms of volume, there is another condition: from which volume the EQ will start working, in the selected frequency range. Differently, a dynamic EQ is a compressor that reduces only the band’s frequency range instead of lowering the entire volume at a certain threshold.

Dynamic EQ is simply connecting EQ with a compressor. If you are a producer or sound engineer, you are probably familiar with both. Still, some other things are essential for you to learn, let’s make a short tutorial for using dynamic EQ:

Step 1: Using EQ as usual

Before you decide on the dynamic characteristics of each frequency region, shape the instrument’s frequency range according to normative EQ rules. Check out our EQ guide to become a master of the frequency ranges.

Step 2: Adjust the threshold level of the range

After we finished messing with the frequencies and adjusting them precisely to the needs of our sound, it’s time to move to the dynamics section first to adjust the desired threshold level. As in the compressor, the threshold level defines from which volume the EQ will start working. It is essential to say that, unlike compression, we do not need to adjust the threshold raising according to the pitch of the sound but the level of oscillation of the selected frequencies up or down.

Step 3: ratio, attack, and release

Of course, there are the parameters such as the ratio (determines what the compression ratio of the compressor will be), the attack (determines how long it will take for the compressor to affect the EQ), and the release (which defines how long the compressor will work). If you want to correct a focused problem in the sound, the recommendation is to leave the attack fast so that the EQ performs the cutting quickly and surgically and does not affect the sound more than necessary.

Fabfilter Pro Q 3 - Dynamic EQ

best dynamic eq

Pro-Q 3 is a dynamic equalizer that allows for precise equalization and dynamic control of any audio source. The plug-in includes up to 24 bands of EQ, mid-side processing, dynamic EQ capabilities, and a real-time frequency spectrum analyzer. Pro-Q 3 makes it simple to create complex equalization curves and shape the sound of any instrument or mix thanks to its intuitive user interface and extensive control options. 

The real-time frequency spectrum analyzer is especially useful for identifying problem areas in the frequency spectrum, and the dynamic EQ capabilities allow for control of individual frequencies based on their amplitude. Overall, FabFilter Pro-Q 3 is an outstanding tool for anyone looking to improve their equalization and dynamic control.

When and how to use dynamic EQ?

There are times when a dynamic EQ will do wonders and when it is recommended to use the standard EQ and make the adjustments as we wish.
So let’s check some cases and see which is more suitable static EQ or dynamic EQ.

The vocals need more clarity.

So we have a somewhat muffled vocal and want to improve it and make it brighter and more pleasant to the ear. The first option is to apply EQ and increase high frequencies complimenting the vocal, and the second option is to increase the same frequencies with dynamic EQ. So, of course, in cases of this type where we want to raise something general like high bass or large areas, we will certainly use a standard EQ and not allow changes to be pumped in our ear dynamically.

A guitar amp recorded a grating sound.

Suppose we use static EQ and look for the harsh frequency in a very focused way and lower it. In that case, a lack of these frequencies will also be created from the guitar’s sound. Still, suppose we use EQ dynamically and let it affect only that the unwanted sound reaches the threshold. In that case, we will have a total frequency range throughout the song except for Minor repairs, so we will undoubtedly prefer the last option.

You have understood the division of roles between the static EQ and its dynamic brother enough, always for you to try to do things against the rules if you want to achieve something unique. Still, in technical problems, it is important to follow the rules.

Conclusion

 It is very easy to fall in love with dynamic EQ because it corrects things that seem irreversible and makes everything easier. Still, it is important to maintain the balance to produce a manageable sound in terms of dynamic and frequency changes.
Good luck on your journey toward the perfect mix.
