IQ-Series DeEsser

The HOFA IQ-Series DeEsser is the best tool for editing harsh sibilance in vocals or in an entire mix. The specialised and very natural sounding voice recognition makes the IQ-Series DeEsser easy to use and very intuitive.

HOFA IQ-Series DeEsser – DeEssing in its most natural form and a BUS mode that is second to none.

The groundbreaking BUS mode can control a selectable frequency range with extraordinary precision.
This makes the IQ-Series DeEsser a game changer for mixing and mastering.



The integrated voice recognition algorithm can control sibilants in a very transparent and effective way. 
The vocal sound remains natural and authentic, even with heavy processing.

The plugin has 3 editing modes for individual tracks and a BUS mode which works with a different and absolutely new algorithm: the frequency range is monitored in high resolution and frequency peaks are attenuated.

User feedback & press reviews:

“I have tested your DeEsser extensively and would like to give you great praise! I have been doing studio work for a long time and I am absolutely stoked about this tool! I have been searching for a long time and have not found anything that is so easy to use and works so efficiently. I record digitally, but with the help of the HOFA DeEsser, I can achieve a sound that comes very close to the old warmth.”

I Love how easy it is to get really good and transparent results with the Hofa IQ-Series DeEsser. Really smooth for vocals. Also love how it handles Guitars Squeaks from acoustic guitars as well as a subtle DeEsser on the Master Bus. A winner and a new go-to DeEsser!

The IQ-Series DeEsser processes “parselmouths” so efficiently and unobtrusively – it’s almost a miracle.

Editors Choice 2015 – Professional Audio

I probably spent cumulative years while trying all sorts of de-esser plugins and painstakingly tweaking them.
IQ-Series DeEsser: basically a one knob (threshold) formula which does the trick in no-time. And the best part: No “sss'” are turning into “fff’s”. Bring on the sibilant vocals now!!

You clearly have the best de-esser on the market and I had no choice but to purchase it. I’ve tested all others and it’s clear your de-esser gives me the ability to get the most natural results quickly. Thank you.

When I used your DeEsser for the first time, I totally freaked out. The processing and the results are simply sensational! Finally a DeEsser that really works. Awesome!
