Wavesfactory Re-Esser 1.0.3 U2B Full MacOS is Here!

Wavesfactory Re-Esser v1.0.3 is not just another de-esser — it is a complete reimagining of how vocal sibilance control should work. By intelligently separating sibilant content from the tonal layer of any vocal or dialogue recording, Re-Esser gives macOS engineers surgical, independent control over each component — taming harshness while preserving or even enhancing the sparkle, air, and detail that make vocals shine. Version 1.0.3 adds a realtime spectrum analyzer on the EQ graph and a brand new formant shifting effect — making it the most capable and creative version yet for macOS producers and engineers in 2026.

What is Wavesfactory Re-Esser?

Re-Esser reimagines what a de-esser can be. Traditional de-essers reduce harshness by attenuating sibilant frequencies — but always at the cost of something else: dulled top end, lispy artifacts, or a processed, unnatural sound. Re-Esser takes a fundamentally different approach — it separates sibilance from the tonal content of the signal into two perfectly aligned layers, then lets you process each independently using 16 built-in studio effects or your own favourite plugins via its grouping system. The result is a level of vocal control that no traditional de-esser has ever been able to offer on macOS.

Version 1.0.3 introduces two significant new additions — a realtime spectrum analyzer on the parametric EQ graph for precise visual feedback during sibilance sculpting, and a Formant Shift effect that lets macOS engineers creatively reshape the tonal character of the separated vocal layers independently. The update is free for all existing Re-Esser owners.

How Re-Esser Works

Re-Esser’s core concept is brilliantly simple yet technically groundbreaking for macOS vocal engineers. It uses a cutting-edge detection system that precisely identifies and isolates sibilant content — the harsh “S”, “T”, and “SH” sounds — without artifacts, guesswork, or manual threshold adjustment. The signal is then split into two perfectly aligned layers:

🔵 Tonal Layer — everything that is not sibilance: the body, warmth, pitch, and character of the voice. 🟡 Sibilant Layer — the separated sibilant content only, ready for independent processing. Both layers sum back to the exact original signal unless you process them — meaning Re-Esser is completely transparent at rest on macOS.

From there you have three paths: use the single Sibilance Level knob for instant one-knob de-essing with no threshold setup required, apply any of the 16 built-in effects independently to each layer, or use the grouping function to route each layer to separate tracks in your macOS DAW and process with any plugin you choose.

16 Built-in Effects

Re-Esser comes with 16 high-quality studio effects that can be applied independently to the tonal and sibilant layers — add, bypass, remove, and reorder them in any combination with a single click on macOS:
