Sibilance

Sibilance is a de-esser plugin from Waves that uses Organic ReSynthesis to break down audio into individual components before processing. It detects unwanted ‘ess’ and ‘shh’ sounds and reduces only their levels, leaving other components—even high-frequency ones—untouched. This results in ultra-precise de-essing that preserves the original timbre, duration, and resonance of the human voice. Ideal for vocals, dialogue, voiceover, and podcasting, Sibilance maintains brightness while removing harshness, even with heavy processing. It offers a variable frequency range from wide to split-band, an informative graph showing de-essing activity, and a variable detection mode for transients or longer ess sounds. A zero-latency version is included for live performance. Whether you’re mixing music or cleaning up speech, Sibilance delivers transparent, natural-sounding de-essing that keeps vocal tone intact.
