FabFilter Pro-Q 3 is a top-quality EQ plug-in with up to 24 bands, perfect analog modeling, dynamic EQ, linear phase processing, and a gorgeous interface with unrivalled ease of use. With its unique Natural Phase mode, it matches both the magnitude and phase response of analog EQing perfectly. Innovative features like Spectrum Grab and collision detection together with its intelligent interactive EQ display make Pro-Q 3 an absolute joy to use.

The Pro-Q 3 app filters the microphone input and plays it back in real-time. To use Pro-Q 3 as a plug-in, you need an AUv3-compatible host app like Auria, AUM or Cubasis. Pro-Q 3 will appear in the list of Audio Unit extensions for effect plug-ins in the host app.

Simply thank you

I would like to thank the team at Fab Filter for affording us IPad producers, the opportunity to have these high quality music tools at our disposal. Very greatful! Was hoping for this! GOD bless you! I pretty much have every music plugin for iOS, but this is the first time I’ve felt compelled to stop and write a review in addition to giving stars.

The Greatest EQ

Update: fixed and working great

Thanks for the quick update!

Developer Response ,

We've just submitted a 3.13 update to Apple with a fix for the problem when opening saved sessions.

Unfortunately we can't offer upgrade discounts for users of the earlier in-app plug-ins in Auria: we don't know who purchased them and the App Store doesn't let us do custom discounts per user. Likewise, we can offer a Pro-Q 2 -> 3 update via the Pro-Q 3 Upgrade Bundle, but this doesn't let us give a discount to existing Pro-Q 2 users if you are purchasing the Pro Bundle right away. The App Store system just isn't that flexible.

This is one of the reasons for the vastly reduced prices on iOS compared to our regular plug-ins for Mac and Windows.
