DMGAudio EQuality

The Final Go-To EQ

EQuality has been designed to be the perfect EQ to let your mixdowns shine. Something for every track of your session. For it to sound at least as good as any high-end console or rack gear, and with all the features and functionality that digital brings.

This is the best mix EQ ever built, but don't take our word for it - test the claim and download the demo!

  • If EQuality and Compassion can't do what you want, you have a problem no EQ or compressor can solve!

    Sound On Sound Review

  • EQuality from DMG audio is the best software EQ I have ever used.

    Far Too Loud

  • This makes other EQs its bitches. The algorithms are state of the art, and the best I've heard. Most importantly the workflow is quick and as detailed as you want it to be without being threatening. EQuality is the pinnacle of EQ design.

    Dom & Roland

  • EQuality is my go to EQ.... it's on most channels most of the time

    Matt Robertson

  • I honestly can't big up this EQ enough, I use it ALL the time and I can't imagine life without it. It has made all other EQs I have seem useless and naff. If you don't own a copy of EQuality yet, one half of me feels sorry for you, and the other half makes me glad I own one and you don't!

    Specimen A

  • The clarity that is possible with EQuality is quite simply second to none, whether mixing down on high end studio monitors or on laptop speakers, the difference is crystal clear, if you are serious about big studio quality mixdowns with proper front to back depth, you need this weapon in your arsenal.

I've been building EQs for nearly a decade. From Focusrite to Sonalksis, I've learned a lot about EQs; how they should sound, how they should work, and I'd always wanted to build an EQ from the ground up, incorporating everything I've learned.

When I first started telling people I was going to do this, the response was a mixture of encouragement, tempered against the question "why do we need another EQ?". I'm pleased to tell you that now, at the end of the development process, everyone who asked that question has their answer. It's an answer that's hard to explain in words, and much much easier to find by just using the plugin. You can click the installer and the "send demo" link, and find out right now.

Most people have quite a collection of EQs - some are models of hardware, some are workhorse EQs for surgical correction, or for guiding a track into a mix, some are for mastering. First off, EQuality is not a model of a specific piece of hardware; it's more ambitious than that. EQuality aims to be a great replacement for all your EQs. That's been the driving factor.

From the bottom up, EQuality sounds as good as an EQ can sound. By that, I mean the prototypes are as close to the consistent analogue shapes as can be achieved digitally, without spending extra CPU. When you want to spend extra CPU to close the deal, you can do that too, but so far not many people have reported finding occasions where the difference is perceptible.

From the top-down, EQuality is designed to allow you to make it work the way you want it to. At every stage, we've sought out any idiosyncrasies in the design, and replaced them with solutions that make sense, and with options to allow you to have things the way you need them.
