FAC Maxima is an audio effect designed to provide automatic gain control of your audio materials to ensure that the levels stay consistent and never exceed 0dB. It's a clever combination of dynamic processors that can be set to provide a gentle transparent signal boost respecting the initial dynamic or significant colorised level maximisation. Thanks to a unique signal path, algorithms and a small set of parameters, FAC Maxima makes a complicated task easy.

In addition to the classic final stage application, FAC Maxima excels on individual tracks too. With a few changes it's easy to go from the common gain deviation compensation, e.g. for vocals, to drastical audio changes that will bring your audio material to new territories: boost reverb tails, flattenize drums… The applications are various and the possibilities are limitless.

• Get the final touch!
FAC Maxima definitely makes audio louder and that makes it an effective tool in many mastering engineers’ arsenals.

• Be creative!
Emphasis subtitle details, sometimes floor contains treasure, you will have a completely new listen to your old tracks! The audio background may indeed contain noise, but sometimes also "pearls" that may be revealed.

• Go further!
Tired by the advertisement boost, or important speech level variation in broadcasting? Use FAC Maxima to maintain the level constant. DJ's may also benefit from the effects to normalise in real time the level of the mixed tracks.

As with all FAC products the interface has a unique sober look and provides a great user experience. FAC Maxima also brings a real-time multi-waveform graph having a 6s buffer of the audio material before and after operations, this will help on setting the right parameters and have a visual feedback.

What's New

Version 1.3

• New waveform viewer: optional scales, mirroring, threshold line feedback, VU Meter Peak/Rms and general widget optimisation.
• Automatic setting of the startup view (small vs large). Can be changed if the host supports the view configuration management.

Easy to use app to boost to your sound!! Gives life to things that need it!

Mets guys

I’m kind of bad at using fancy audio tools like compression, limiters, maximizers, and all of those things. They make a huge difference if you can use them, but I’ve always cared more about other things. So, an app like Maxima by FAC is amazing to me. I have no problem using it and getting good results from it. I’ve only been playing with it the last few hours. I’ve done everything from adding some extra oomph to an old track without taking anything away from it’s original integrity, Giving my Novation Circuit and Volca Beats some extra life they never knew they had and that Volca Beats really needs something like Maxima or it sounds awful. I managed to get a really subtle extra punch on a piano sound that I still had plenty of dynamics and natural sound to work with. And since it’s AU3 you can just toggle it on\off with MIDI commands in a host app like AUM. Seriously, I bought a 6 pack of beer for $9USD drank 2 and they are gone. This app is $7USD and I’ve used it the past few hours and it keeps on giving and is going to give more. I’ll probably put it on the master out most of the time, and then if something in particular needs help there it is.

FAC makes the difficult task of not overdoing limiting easy as can be...


For the past 2+ years I’ve used iOS for music production exclusively, putting away my desktop DAW laptop in a closet, there’s been very few desktop quality options for mastering/limiting. My main DAW is Auria Pro, so I do have access to the long time best option iOS offers, the FabFilter desktop quality plugin Pro-L. But many iOS producers don’t use Auria for one reason or another, so they’ve been shut out of using Pro-L as FabFilter’s are exclusive to the Auria environment only.

With Maxima, FAC has made the kind of professional, brilliant sounding limiting/compression that pro desktop plugs like Pro-L deliver available to ALL iOS music makers using an AUv3 host (basically all the main iOS DAW’s at this point, including GarageBand). Sound quality, like beauty to the eye, is in the ear of the beholder, so for me I can say without hesitation that Maxima is absolutely in the same league as best limiters/maximizers available on desktop.

Lastly, since most streaming services all have loudness level protocols, the “Loudness Wars” of the past 15 years are all but mute. Limiting isn’t about making music as loud as possible, it’s about putting a “glue” over the audio, making each frequency & instrument sit well with all the others. Having a master that sounds present & full is imperative and shouldn’t be confused with just making everything loud. Maxima does this beautifully and without a lot of hassle. Highly recommended.



This brings life and presence to anything you put it on. Totally love it
