Surgical sibilance reduction targeting a narrow high-frequency band — eliminating harsh 's' and 't' sounds while preserving the brightness, clarity, and presence that make audio come alive.
The De-Esser uses a split-band architecture where only the sibilant frequency range is affected. The rest of the spectrum passes through untouched. Unlike broadband de-essers that dull the entire top end, MixBus targets only what needs fixing — preserving all the brightness and detail your audio needs.
ProcIQ adjusts de-esser sensitivity based on content classification. Speech-heavy talk radio gets more aggressive treatment. Music gets a lighter touch. Mixed formats get per-segment adaptation — ensuring sibilance control is always proportional to the content it encounters.
The De-Esser is critical for voice-heavy formats: talk radio, news, and podcasts. It's also essential after pre-emphasis (stage 11) which can amplify sibilance. Positioned before the limiter, it prevents sibilant peaks from triggering unnecessary limiting — keeping your dynamics clean and your highs intact.
Sibilance eliminated with pinpoint precision — brightness and presence preserved.
