EQ3 (iOS) v2.0.0
EQ3 (iOS)

In the ’80s it was the first to use a different approach to tonal adjustments. In conventional analog equalizers, whether they are shelving, sweepable, graphic or parametric types, various sections of the audio spectra are boosted or attenuated by adding or subtracting bandpasses. In this case, frequency shaping is achieved by summing bandpasses. Our emulation of this method is quite similar to the original and improved with additional possibilities of digital technology. Now you can hear it for yourself. 

There are five broad, overlapping, interacting bands: 10 (Sub), 40, 160, 650 and 2.5 кHz, along with the «rock (airy) band» control, which is an HF boost-only control.


  • Standalone and AUv3 plug-in;
  • Precise port of Rack Extensions plug-in;
  • Modeled vintage EQ;
  • Boost only shelf at 2.5 kHz, 5 kHz, 10 kHz, 20 kHz and 40 kHz;
  • 2.5 kHz fixed boost and cut shelf;
  • 650 Hz fixed boost and cut bell;
  • 160 Hz fixed boost and cut bell;
  • 40 Hz fixed boost and cut bell;
  • SUB (10 Hz) fixed boost and cut bell;
  • Stereo (Mono), Mid or Side EQ modes;
  • Saturation On/Off-button;
  • Undo/Redo;
  • A/B;
  • 2x/4x/8x Upsampling.

When using the EQ3, remember that the bands are broad, approximately 2 octaves. They overlap one another. For example: when boosting the 10 kHz «rock band» to a +6 position on the knob, to keep the response flat through in 2.5 kHz region you should rotate the 2.5 kHz coarse knob to about a -1 position. The amount you back off the 2.5 kHz control should, of course, be set by ear. Following this kind of procedure will accomplish a more airy sound, with much more clarity.

You can accomplish the same thing for the low frequency response by applying the same principles. The EQ3 will reach further into your mix than you’ve ever heard before with minimal phase distortion.

As a result, you may need to take a little time and «play around» with the controls on the EQ3 before you can make intuitive adjustments.

To use EQ3 as a plug-in, you need an AUv3-compatible host app like GarageBand, Auria, AUM, Cubasis and more — EQ3 will appear in the list of Audio Unit extensions for effect plug-ins in the host app.

Reviews and Ratings

Finally an Maag style EQ with Airband
Just get this EQ if you are looking for a great Maag style EQ it sounds great and works with all of the iPadOS DAWs. 5 dollars for an EQ this good is a great deal KEEP THEM COMING.Joe Salyers (USA, App Store)

Loving this one
You made an amazing job emulating the Maag EQ4 on this one. Simply beautifulCamilo Calvo (Columbia, App Store)

The eqs are good and easy to use... I'm waiting for other effects like reverb delays etc to be released.Jampick (Philippines, App Store)

Pleeease Make bundle
Great plugins!!! I really like the sound of equalizers, great design for the mobile version of these pieces of iron, and the preset sets simplify the work quite a lot, as they are well suited to almost any task. But please make a bundle of all equalizers or all plugins in General! It is not very profitable to buy each equalizer separately, when there is a need for all of them( Thanks for your work!!!w.offender (Russia, App Store)

What I’m really digging with these is they each have a personality, like the analog hardware units they’re influenced by. If I want a particular character these RRS are all different and the analog saturation is very cool, helping that aim. You can hear it’s really doing something unlike some saturation effects that are just too transparent.JRSIV (forum.audiobus.us)

It’s modelled on the Maag EQ4. Tried it out and it’s good. The fixed frequency bands are well placed and because of that it is very quick to use. Tried it on the master channel and it was easy to turn a muddy sounding mix into something with definition and clarity.Mark B (forum.audiobus.us)

I salute them for allowing full demo even if short! Other devs, please take note. And this DOES sound really wonderful, wow, love it. Very warm and rich. And yet, it does indeed have that airy quality, hmmm, good stuff.Gavinski (forum.audiobus.us)

Holy sh!t, Maag on iOS? Making music on iPad getting more and more exciting.lazyass (forum.audiobus.us)

No way in hell I wanted to buy an eq, but after demo-ing it a few times I was sold. I’ll add that this is a really great EQ if you don’t know much about EQing, it is pretty easy to dial in something good-sounding. As mentioned, the bands seem really well chosen.Gavinski (forum.audiobus.us)

Remarkably good Maag style EQ! Unreal for the price.ryantereu (USA, App Store)

Great EQ!
Get them all!anickt (USA, App Store)

Очень даже неплохо!
Прекрасный эквалайзер, кроме «воздуха», что секция Air, остальные линейки эквализации очень корректно работают со звуковым сигналом. Это не копия Maag — но нечто довольно близкое, со своим «окрасом» звука!rusbroadcast (Russia, App Store)
