Waves Clarity Vx vs iZotope RX: Which One Actually Cleans Up Noisy Vocals?
The noise problem nobody solves with EQ
You’ve got a vocal take that’s 80% great. Right performance, right mic, right room. Then there’s the fridge hum, the laptop fan, the neighbor’s HVAC. You can automate a gate, you can notch out the 60 Hz rumble, but the broadband hiss that sits underneath the consonants doesn’t move for a static EQ. That’s the job people buy Waves Clarity Vx or iZotope RX for: separation, not tone shaping.
I’ve run both on the same problem takes, and they’re not competing at the same game. One is a fast, mix-insert noise reducer. The other is a suite built around spectral repair. If you’re picking one, you need to know which job you actually have.
What Clarity Vx actually is
Waves Clarity Vx is a single-module AI speech-focused noise reducer. You load it, it analyzes the signal, and it throws out a broadband noise floor while trying to keep the vocal intact. Controls are minimal by design: a reduction amount and a couple of shaping options, then a mix. No node selection, no spectral painting. That’s the point.
On a real insert chain the workflow looks like this: I put it first, before the compressor, and let it chew on the raw file. Because it’s linear and clean, it doesn’t smear transients the way a classic broadband expander does. On dialogue-style vocals or a close-mic’d pop take recorded in an untreated room, it’s genuinely quick. Ten seconds of setup, move on.
Where it trips: it has opinions about what counts as voice. On a whispery intimate take or a breathy indie vocal with a lot of air, higher reduction settings start eating the soft consonants and leaving a faint metallic residue. Back it off and the hiss creeps back. There’s a sweet spot per take, and you’ll find it, but you’ll hunt for it.
What iZotope RX actually is
RX is a repair suite, not a single insert. The Spectral De-noise module alone is a different philosophy: you feed it a noise profile from a section of the file that’s just noise, then it subtracts that profile from the whole take. You also get Spectral Repair for surgical fixing of one-off events, mouth de-click, de-hum, and the rest of the toolbox. It’s post-production software that happens to be excellent for music cleanup.
The upside is precision. If the problem is one specific fan tone, one chair creak, one plosive, RX isolates it. You’re not asking an algorithm to guess what’s noise. You’re telling it. That’s a real advantage on problem material.
The downside is that RX is a workflow, not a plugin you slap on and forget. You’re either working in the standalone editor or in the RX module inside your DAW, and you’re manually defining profiles and decisions. On a 40-track session, that’s a time tax. Worth noting for anyone wondering about the long-term direction: iZotope is now under Boris FX, and the company has stated plugin development continues without interruption with the teams behind RX, Ozone, Neutron, and Nectar staying in place. So the suite is not being abandoned, whatever your feelings about the acquisition.
The honest comparison
| Clarity Vx | iZotope RX | |
|---|---|---|
| Approach | AI single-insert reducer | Suite, profile-based spectral repair |
| Setup time | Seconds | Minutes per problem |
| Broadband hiss | Very good at moderate settings | Excellent with a clean noise profile |
| One-off events | No | Yes, Spectral Repair |
| Learning curve | Low | Real |
| Best in | Mix insert | Editing / post workflow |
If your problem is a steady, broadband noise floor and you want to stay in the mix, Clarity Vx wins on speed and transparency. If your problem is anything else (clicks, hums, isolated blips, or a nasty specific tone), RX wins because it gives you the tools to target it.
Where Clarity Vx gets annoying
It’s not a source separator. It won’t pull a vocal out of a busy mix, and it shouldn’t be sold as that. It also doesn’t love already-processed material. Run it after a heavy compressor and it has more trouble reading what’s voice versus artifacts. Put it first and it behaves better. That’s a real constraint on how you build the chain.
Where RX gets annoying
It’s slow by nature. Defining a noise profile on every take adds up, and the standalone editor is a different headspace than a DAW session. The suite is priced and structured for post work, not for a bedroom producer who just wants the hiss gone by dinner. If that’s you, you’re paying for capability you won’t use.
Do you actually need either
Before you spend anything, know that a free chain handles a surprising amount of this. TDR Nova is a dynamic EQ that works like a surgical tool on vocals; you can cut, boost, or let it react dynamically to specific frequencies, which is perfect for de-essing, controlling boxiness, or smoothing harsh top end, and it’s transparent enough to zero in on problem areas without wrecking the voice. Spitfish for de-essing, Limiter №6 for control, and Youlean Loudness Meter to keep you honest round out a chain that Major Mixing describes as genuinely good. Paid plugins buy workflow and character, not results you otherwise couldn’t reach.
So the real question is whether your noise problem is dynamic or broadband. If it’s harshness or boxiness, Nova handles it. If it’s a floor that won’t move, you need a reducer, and that’s where Clarity Vx or RX earns its slot.
My verdict
For most people reading this, Clarity Vx is the right first buy. It solves the common case fast, stays in the insert chain, and doesn’t demand you learn a new application. The trade-offs are real: it has a ceiling on how much noise it can pull without artifacts, and it’s not a repair tool.
RX is the right buy if you’re cleaning up spoken word, podcast, film, or genuinely damaged takes where you need to fix specific events rather than dampen a floor. It’s more powerful and more precise, and you pay for that power in time and money. Both are legitimate. Neither replaces the other. Pick based on the noise you actually have, not the demo that looked impressive.
