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