Fixed a bug that could cause the spectrum analyzer to show peaks at slightly incorrect frequency values.

A Fantastic EQ with Great Resource Efficiency

I can use this on every track because of its very clever programming to be very lightweight on the iPad’s resources. Fully featured, including dynamic EQ, side-chaining, multiple filter types and so much more. I say rubbish to the complaint about the accuracy of the on-screen scales. You EQ with your ears, not your eyes. I will use the on-screen scales to get me close when going after a known issue, but in the end you cut, boost, and filter with your ears. There’s a reason that engineers all over the world are raving about FabFilter’s EQs and the rest of their plugins. They’re all fantastic tools!!

good, but exclusion of keybinds has made EQ-ing become fatiguing

ive been using fabfilter proq3 for 5/4 months now and its been a good experience so far. only complaint i have is the exclusion if keybinds. i got an ipad keyboard accessory recently for doing longer session editing, and not having keybinds for shaping an eq point makes for a tedious and at some times an uncomfortable experience.

it makes sense why it isnt included as not everyone has a ipad keyboard. but if you're getting serious and planning to work more hours on a song, its needed.

ive been doing longer editing sessions, cleaning up some songs i made a few hours earlier, and having to press my finger down constantly on a mouse pad to shape a bell curve or manually changing the slope of a low cut / high cut has been hurting my finger a ton while also making it slower to EQ.

It's gotten to where im just avoiding the EQ, which i don't want to.. but it's hard to give it a try after it becomes so fatiguing.

besides that, i've been enjoying proq3 so far! it's been good, but this exclusion of an important feature has made it difficult to EQ a track.

please implement keybinds as a toggle in a future update. thank you for your work :)

Inaccurate

It absolutely is inaccurate. When you do a long hold and the frequency peeks are displayed the numbers are off. Definitely not a PRO app. Fix it.

The Best

My favorite surgical+ EQ on any platform: MacOS, Windows, or iOS. It’s packed with features, but the beauty of the app is its perfect interface. It’s a joy to work in.

game changer

Pro Q helped me really grasp the concept of additive and subtractive EQ while it enabled me to perform those tasks more efficiently. The cross-track visualization component and surprisingly low DSP usage really puts the bow on the present and shuts the mouth of any fab filter naysayers. I was able to afford one FabFilter app and I was very happy I made that decision Pro Q when my mixes started immediately improving and sounding so much more professional. Looking forward to slowly collecting all of these desktop-level apps for my ipad.
