RysUpDS vs Waves Sibilance: Which De-Esser Should You Use in 2026?

How Waves Sibilance works

Most de-essers are a compressor that only listens to the high frequencies. Sibilance takes a different route. Waves says it breaks the sound into basic components before processing and then reduces only the "ess" and "shh" parts. The technology is called Organic ReSynthesis.

The controls are simple:

• Threshold sets when de-essing starts.
• Range caps how much reduction can happen.
• Detection moves between short transients and longer ess sounds.
• Mode goes from Wide to Split, so you can process the full band or just the highs.
• Lookahead and Monitor buttons, plus a scrolling graph that shows where de-essing happened.

There is also a zero latency Live version for stage use. With lookahead on, Waves lists latency at 529 samples at 44.1 kHz and 576 samples at 48 kHz.

What it does well: it is quick, it is hard to make sound terrible, and the resynthesis approach keeps tone well under heavy reduction. That is a real strength, and we are not going to pretend otherwise.

How RysUpDS works

RysUpDS is a detector driven de-esser built for vocals. The main view is Threshold and Range, so day to day it is as fast as Sibilance. The difference is what is under the hood when a vocal fights back.

• Threshold from -50 to 0 dB and Range from 0 to -50 dB of reduction.
• HPF and LPF detection band with a Q control. The default listens from 3 kHz to 9 kHz, and you can move it to wherever your singer's S actually lives.
• Single Vocal and Allround modes, so the detector can focus on one voice or handle full mixes and buses.
• Wide Band or Split Band processing, the same core choice Sibilance gives you.
• Audition to solo exactly what is being removed.
• Mid/Side modes (Stereo, Mid Only, Side Only) and a Stereo Link amount for doubles and stereo stacks.
• Advanced timing: Lookahead from 0 to 15 ms, Ratio from 1:1 to 20:1, Attack, Release and 1x, 2x or 4x oversampling.

Why the detection band matters

Every singer's sibilance sits somewhere different. A deep male rapper might hiss around 4 to 5 kHz. A bright female pop voice can spike at 7 to 9 kHz. A cheap condenser mic can add its own peak on top.

Sibilance makes that decision for you. Most of the time it guesses well. When it does not, you have Detection and Mode, and that is it.

RysUpDS lets you set the band. Hit Audition, sweep HPF and LPF until you hear only the S, then let Threshold do the work. That is the difference between "it removed some of the harshness" and "it removed exactly the harshness". Our how to de ess vocals guide walks through this step by step.

Feature table

Honest note: Sibilance ships a dedicated zero latency version, which matters for live sound engineers. If you mix FOH every weekend, that is a real point in its favor. For studio vocals, the extra control in RysUpDS matters more.

Sound and workflow

Light de-essing

On a clean vocal that only needs a few dB on the worst S's, both plugins do the job. Pull Threshold down until the gain reduction meter only moves on sibilant words, keep Range around -4 to -6 dB, and you are done in under a minute either way.

Heavy de-essing

This is where the two split. Sibilance's resynthesis is designed to keep tone when reduction gets deep, which is its best trick. RysUpDS takes a different path: narrow the band so the processor only touches the S, switch to Split Band so the body of the voice is never turned down, and add 2x or 4x oversampling if the top end sounds grainy. You get to choose the trade off instead of trusting an algorithm.

Stereo vocals and buses

Doubles and stacked hooks often have sibilance that does not line up. RysUpDS's Stereo Link lets you unlink the sides so each double is handled on its own, and Mid Only or Side Only modes let you clean up wide stacks without dulling the center lead. Sibilance gives you mono and stereo instances without those options.

Where it sits in the chain

Put either one after your first compressor and before reverb, delay and any air boost. Compression brings sibilance up, and reverb makes it splash. See the full vocal chain order guide for where everything goes.

RysUpDS settings for common vocals

Start with these, then trust Audition and your ears.

1. Rap vocals: HPF around 4 kHz, LPF around 9 kHz, Wide Band, Threshold until you see 3 to 6 dB on the S's, Range at -8 dB. Rap S's are short, so keep Release fast.
2. Bright pop and R&B leads: move the band up, HPF around 5.5 kHz and LPF around 11 kHz, switch to Split Band so the body of the voice is never turned down, and add 2x oversampling if the top end sounds grainy.
3. Deep male voices: sibilance often sits lower, around 3.5 to 6 kHz. Sweep the band with Audition on until you only hear the S.
4. Stacked doubles and harmonies: use Allround mode on the stack bus, lower the Stereo Link amount so each side reacts on its own, and keep Range gentle at -4 to -6 dB.
5. Full mix or vocal bus: Allround mode, Mid Only if the lead is the problem, Side Only if bright stereo hats and stacks are.

Check your work by bypassing and listening at low volume. If the vocal sounds like it has a lisp, back off Range or narrow the band.

Signs your de-esser is set wrong

• The singer sounds lispy. Too much Range, or the band reaches too far down into the voice. This happens with any de-esser.
• Everything gets dull, not just the S's. You are in Wide Band with the threshold too low. Switch to Split Band or raise the threshold.
• The S's still splash in the reverb. The de-esser is after the reverb, or the send is before it. Move it earlier.
• Breaths and T's disappear. Release is too slow or the band is too wide. Narrow it and speed up release.

If the problem is harsh resonances across the whole vocal, not just S's, a de-esser is the wrong tool. Try RysUpSmooth, a dynamic resonance suppressor, before or after RysUpDS.

Pricing comparison

Let us be straight about this. On sale, Sibilance is cheaper than buying RysUpDS on its own. If all you need is one de-esser and you catch the sale, that is a fair deal.

Here is why the math still favors RysUpDS for most producers. RysUpSuite is $9.99 a month billed yearly and covers RysUpDS plus every other paid Rys Up plugin: RysUpTune, RysUpEQ, RysUpComp, RysUpSmooth and the rest, plus every future plugin. Subscription payments also count 100% back toward owning individual plugins. That is a whole vocal chain for less than a few single plugins.

Built new, updated constantly

Sibilance has been around for years and does what it was designed to do. RysUpDS is a 2025 to 2026 build that keeps moving. The current release is version 1.3.21, and our plugins get fixes and improvements on a near daily cadence through RysUpHub, which installs and updates everything in one place.

That matters for a de-esser more than you might think. New DAW versions, new macOS releases and new Windows builds break old plugins. A small team that ships every day fixes those problems in days, not in the next annual update.

Who should use which

• Pick Waves Sibilance if you already own a Waves bundle or subscription, you mix live and need the zero latency version, or you only ever want three knobs.
• Pick RysUpDS if you mix vocals in the studio, your singers have sibilance in unusual spots, you work with stereo doubles and stacks, or you want the de-esser as part of a full modern vocal chain.

Questions producers ask

Is RysUpDS better than Waves Sibilance? For studio vocals, RysUpDS gives you more control: an adjustable detection band, audition, mid/side, stereo link, ratio, attack, release and oversampling. Sibilance is simpler and has a dedicated zero latency live version.

How much does Waves Sibilance cost? Waves listed it at $34.99 on sale with a $79 MSRP on October 21, 2026. Waves also sells subscription plans that bundle many of its plugins.

What is Organic ReSynthesis? It is Waves' technology that breaks a sound into components before processing, so Sibilance can reduce the ess and shh parts while keeping the rest of the tone.

Does RysUpDS work in Pro Tools? Yes. RysUpDS ships as AU, VST3 and AAX on Mac and Windows.

Where should a de-esser go in a vocal chain? After your first compressor and before reverb, delay and air or exciter plugins, so you catch sibilance that compression brings up before effects spread it out.
