IQ-Series DeEsser

The HOFA IQ-Series DeEsser is the new tool for editing harsh sibilants in vocals or in the whole mix. With a specialized and very natural working voice recognition the IQ-Series DeEsser is very easy to use and even more intuitive.

Furthermore, an innovative BUS-Mode can control an adjustable frequency range in extraordinary precision. 
All this makes IQ-Series DeEsser a game changer in mixing and mastering.

The integrated voice recognition is able to control all kinds of sibilants (s, sh, ts, …) completely smooth and effective. The vocal sound remains natural and authentic even with strong reduction.

Besides the 3 modes for editing individual tracks, there is a BUS-Mode which works on a completely different and absolutely novel algorithm:
a high resolution monitoring and processing defuses all occurring frequency peaks simultaneously.

HOFA IQ-Series DeEsser – DeEssing in its most natural way and a BUS-Mode that has no equal.

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

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.

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!!
