Split-Band
Sibilance Control

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.

Pinpoint Precision

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.

  • Split-band architecture isolates sibilant frequencies
  • Narrow-band targeting leaves the rest of the spectrum intact
  • Full HF content preserved outside the sibilant range
  • Pinpoint accuracy eliminates only what needs fixing

Content-Aware Sensitivity

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.

  • ProcIQ-driven content classification
  • Aggressive treatment for speech-heavy formats
  • Lighter touch on music to preserve sparkle
  • Per-segment adaptation for mixed-format programming

Broadcast-Ready Sibilance Control

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.

  • Per-content sensitivity adapts to every source type
  • Zero dulling — brightness and presence fully preserved
  • Real-time sibilance detection and reduction
  • Pre-limiter positioning prevents sibilant peak triggering
