IQ-Series Limiter

If you’re looking for the (mastering) limiter, that makes your productions as loud as possible, you’ve finally found it.

Just make it LOUD!

The IQ-Series Limiter convinces with a clear design, instead of trying to impress with countless controls. The plugin is reminiscent of an exclamation mark – and that’s exactly what the processing will do to your productions!

Top producer Karl “Charlie” Bauerfeind:

“…The IQ-Series Limiter is the most precise and transparent limiter in the low frequency range that I have come across in over 20 years of DAW and plugin experience. A real weapon.”

Sound engineer and producer for bands such as Blind Guardian, Gamma Ray, Gotthard, HammerFall, Helloween, Motörhead, Rage, Saxon, Van Canto, Venom, Inlegend and many more.

After we released the IQ-Series Limiter, we were really happy to see that many customers gave our intelligent loudness tool a place in their virtual mastering chain. When the plugin received “Best of Equipment”, “Editor’s Choice” and “Reader Awards” it became clear, that the combination of super-easy operation and highly professional results is simply convinving.

User feedback & press reviews:

… it doesn’t change the source sound in any direction except by being louder. Actually, that is all I want from a limiter.

As a user you get an easy-to-use brickwall limiter with a convincing sound quality – even when used with extreme settings – and an affordable price. What more could you ask for?


The HOFA IQ-Series Limiter is a sophisticated and professional mastering tool at a fair price. The sound quality is on the highest level and the handling is exemplarily easy. No matter how you look at it, this limiter has to be recommended.

… so easy to handle and convinces with an excellent sound.

Editors Choice 2014 – Professional Audio

Our two standard limiters were replaced by the HOFA IQ-Series Limiter, which we meanwhile use in all of our productions. It works brilliantly with very dynamic songs, sounds much more transparent and more natural than the much acclaimed Slate FG-X, and does not tend to “pump” like the FabFilter. A big compliment to the programmer, who managed to combine an absolute top-plugin with simple handling.

In the world of too many knobs & adjustments, HOFA IQ-Series Limiter nails it beautifully with the simple 2 knob design. This plugin just does what it says: “LOUD” !!!
Whether mastering or on single instruments, you’ll love what it brings to your productions.
Clean with just enough snap, HOFA IQ-Series Limiter delivers the goods !!!

Last week I was wrapping up an album project that I have been producing, recording and mixing for a client over quite a long period. I had been tasked with the mastering process as well. I had taken such care with the whole process, that when It came to the mastering process I was pretty dissatisfied with the result that I achieved bringing up the level of the final mixes with one of the industry standard maximisers. Ironically at the same time I received an email from HOFA about the IQ-Series Limiter so decided to try out the demo. I can happily say that the IQ-Series Limiter retained the integrity of the sound that I had achieved throughout the album production, and that it ended up being the final limiter on all tracks of the album.
Thank You HOFA.

I just wanted to thank you for this really ingenious limiter!
It makes mastering a lot easier for me.

The HOFA IQ-Series Limiter is a beast. It is not only clear and transparent, it keeps transients in the mix intact and perfect. The GUI is simple and intuitive, but there are many things going on in the background with this limiter that help you to achieve the best possible final mix. HOFA did not receive The Reader Award 2015 BEST PLUGIN for the HOFA IQ-Series Limiter for no reason. It is a fantastic piece of software, and whether you are a home recording enthusiast or a professional engineer, you would be a fool for not trying out this limiter on your projects.
