Soothe2 Alternatives (2026): Free, Stock and Paid Ways to Tame Resonances, Compared by Job (and What soothe3 Changed)

The short answer: nothing free does exactly what soothe does, but two free tools cover most of the job if you're willing to aim them yourself. TDR Nova is the closest: up to four dynamic EQ bands that only cut when a harsh frequency spikes, so you find the problem and Nova handles the timing. Techivation T-De-Esser 2 is the fast one: point it at a range and it tames harshness and sibilance with a handful of controls, by turning the whole signal down when that range gets loud. Every major DAW also has a stock route: DeEsser 2 in Logic, Multiband Dynamics in Ableton, Maximus or Fruity Multiband Compressor in FL Studio, Dyn3 De-Esser and Pro Multiband Dynamics in Pro Tools. If you pay, FabFilter Pro-Q 4's Spectral Dynamics mode, Techivation M-Clarity 2 and Waves Curves Equator get closest to soothe's automatic behavior. What you give up going free is automation: soothe finds and follows resonances across the whole spectrum by itself, and the free tools need you to find them first.

Harshness is the most common problem in the vocals people send me, and the one I chase hardest on my own releases (Sony, Universal, Ultra, Dim Mak), because it's what makes a listener turn a song down without knowing why. No affiliate links on this page. Full disclosure: FabFilter lists me as a featured artist, and I'd recommend their plugins either way. I sell mixing services, disclosed at the end.

First: soothe2 is now soothe3

oeksound's soothe2 page now redirects to soothe3, the third version, which launch coverage dates to May 2026. soothe3 is what oeksound sells today, with an upgrade option on its page for existing owners. A few facts from oeksound's own page, so you know what you're comparing against:

• What it does: it identifies problematic resonances automatically and applies matching reduction, for harshness, muddiness, boominess, proximity effect and piercing sibilance, while keeping the original timbre.
• Two modes: "In soft mode, Soothe3 tackles most problems transparently." Hard mode is "more reactive to dynamics," closer to a compressor's grab, and oeksound suggests it for creative overdoing.
• New in 3: a Detail control (a testimonial on oeksound's page calls it the biggest upgrade from soothe2), tilt controls, a low latency mode for tracking, an optional linear phase mode, and multichannel support up to 9.1.6.
• Buying: VST3, AU and AAX on Windows and macOS, an iLok account (no dongle), a fully featured 20-day trial, and all purchases final. Check oeksound.com for the current price.

If you already own soothe2, you can keep using it; the question this page answers is what does the same job if you don't own either, or don't want to pay.

What soothe actually does (and why it's hard to copy)

A static EQ cut is always on. A dynamic EQ band (Nova, Pro-Q) only cuts when its one frequency crosses a threshold. soothe goes further: it analyzes the whole spectrum all the time, finds the narrow peaks that stick out from the sound around them, and cuts each one only while it sticks out, at many frequencies at once. When a singer moves from an "ee" to an "ah," the harsh resonance moves with the vowel, and soothe follows it without you placing a band.

That's the gap every alternative is trying to close, in one of three ways:

Two tools often listed as soothe alternatives aren't resonance suppressors. Wavesfactory Trackspacer ducks one track using another track's spectrum (it's in the best sidechain plugins), and Waves Curves Resolve carves space between two tracks where they mask each other. Useful, but a different job.

The free picks

TDR Nova. Tokyo Dawn Labs' free dynamic EQ, and the closest free tool to soothe in sound. Each of its four bands can be static or dynamic: set a Bell on the harsh frequency, leave its Gain at 0, turn on Threshold, and lower it until the band only moves when the singer pushes. It also has an external sidechain and a Diff (side) target for harshness that lives in the stereo width. The catch is that you do the finding, and four bands is four frequencies. Every control and a settings chart by job are in the TDR Nova guide.

Techivation T-De-Esser 2. Free for personal and commercial use, in VST, VST3 and AAX on Windows, VST, VST3, AU and AAX on macOS (Intel and Apple Silicon), and AUv3 on iPad. Techivation describes it as smoothing high frequencies to reduce sibilance and harshness, and lists harshness on close-mic'd sources, glare on bright guitars and pianos, piercing synths and overheads among its uses. The controls: Frequency Range (four modes for where it listens), Processing (the threshold), Intensity (like a ratio), Sharpness (like a knee), Make Up, Mix, Quality (oversampling off to 8x), and Filter and Diff switches to hear the detected range or what's being removed. One difference from soothe matters: when the range crosses the threshold, it compresses the whole signal. That's fast and natural on a vocal, but it isn't a narrow cut.

The stock route

You may already own a usable version.

• Logic Pro. DeEsser 2 is more flexible than its name. Apple's guide describes a Frequency knob, a Peak filter "to reduce specific frequencies in a narrow range" or a Lowpass filter for a broad range, a Split range button that reduces only the filtered band (Wide reduces everything), Threshold, Max Reduction, a Relative mode that compares the filtered band with the full signal, and Filter Solo to hear the band. Set Peak, Split and Relative, and aim it at the harsh frequency, within the range its Frequency knob covers. Multipressor handles broader bands. The Logic Pro vocal chain shows DeEsser 2 in context.
• Ableton Live. Live has no dynamic EQ or dedicated de-esser. Multiband Dynamics (Standard and Suite) does the job with one band working: set the crossovers around the harsh range and compress only that band. The Ableton vocal chain has the settings.
• FL Studio. Image-Line's plugin list has no dynamic EQ or de-esser, but Maximus and Fruity Multiband Compressor ("three independent frequency bands") both work with one band compressing. Check Image-Line's edition chart for which ones your edition includes. The FL Studio vocal chain covers Maximus.
• Pro Tools. Dyn3 De-Esser for the top end, and Pro Multiband Dynamics where your tier includes it, with one band set on the harsh range. The Pro Tools vocal chain shows both.

Every stock route is a range-triggered tool, not a spectral one: a band you set, compressing as a block. Keep the band narrow and the reduction small.

The paid picks

FabFilter Pro-Q 4. Any Bell or Shelf band can be dynamic, with attack, release, side-chain filtering and external triggering. The soothe-like part is Spectral Dynamics: per FabFilter, a spectral band "triggers per specific frequency within a band when it exceeds the threshold," without changing the gain of the whole band. Put a wide spectral band over 2 to 6 kHz on a vocal and it cuts only the peaks inside it, wherever they land. You still decide where the bands go, and reviews (MusicTech's among them) say it doesn't fully replace soothe for whole-spectrum suppression; it's the pick when you'd rather own one EQ that does both. Free stand-ins for the rest of FabFilter's range are in the FabFilter alternatives.

Techivation M-Clarity 2. A dynamic resonance suppressor that "removes muddiness, boxiness, and harshness," in Techivation's words, at $129 list with a 14-day trial. The controls read like soothe's: Suppression, Intensity, Focus, Attack and Release, Soft and Hard modes, a Frequency limit, Left-Right or Mid-Side processing, Mix Assist, auto gain, and Diff and Filter switches to hear what's removed. VST, VST3 and AAX on Windows, plus AU on macOS (Intel and Apple Silicon).

Waves Curves Equator. Waves calls it "smarter resonance suppression & frequency unmasking": it "learns" your content and offers a personalized suppression curve, for full mixes, vocals and instruments. Waves' product listing shows it as part of its Ultimate subscription; check waves.com for individual pricing. The natural pick if you already work in Waves.

soothe3. The upgrade, not an alternative, but worth the 20-day trial before you decide: if you spend hours placing dynamic bands on vocals every week, the automation is what you'd be paying for.

Settings chart: starting points by job

Two routes for each job: a resonance suppressor (soothe or a paid alternative) and the free dynamic EQ route (TDR Nova, a dynamic band with Gain at 0 and Threshold on). Match levels and listen to the quiet parts.

On a master, everything is smaller: 1 to 2 dB of dynamic reduction is a lot, and if a resonance suppressor is working constantly on the master, the problem belongs on one channel. How to fix harsh vocals walks through finding the cause before you reach for any of these, and the best de-esser plugins covers the esses on their own.

What soothe does that the free ones don't

Honest list, so you know what you're giving up:

1. It finds the resonances. Nova and the stock tools need you to sweep and place every band.
2. It follows them. A vowel change moves the harsh peak; soothe moves with it. A dynamic band stays on its frequency. (Pro-Q 4's Spectral Dynamics tracks peaks inside a band, which is why it's the closest paid EQ.)
3. It works on many frequencies at once. Nova has four bands; a de-esser-style tool has one detector.
4. It cuts narrow peaks, not the whole signal. T-De-Esser 2 and the stock de-essers turn down the full signal or a whole band on every trigger.
5. It's fast to set on every vocal. That's the real product: minutes saved per track, every session.

What the free tools do as well as soothe: one known harsh frequency, a ringing note, esses, a cymbal spike. For those, TDR Nova is genuinely enough.

Which one to pick

• No budget, one harsh spot: TDR Nova.
• No budget, fast and broad: T-De-Esser 2, or your DAW's de-esser on the harsh range.
• You'd rather own one EQ that does it all: FabFilter Pro-Q 4.
• You want soothe's workflow for less: try M-Clarity 2 or Curves Equator on their trials.
• You fight harsh vocals every week: trial soothe3, because time is what it sells.

If you're trimming plugin spend across a whole chain rather than one plugin, the iZotope Ozone alternatives apply the same free-first logic to mastering suites.

Where I land (and the disclosure)

Start with TDR Nova on the frequency you found by sweeping, and a de-esser for the esses. Most harsh vocals are fixed there, for free. Pay for automation when the hours add up, and trial before you buy, because every tool on this page sounds different on your voice.

Harshness is one of a dozen decisions that make a vocal sit, and it only works when the compression, EQ and saturation around it aren't creating it. If you'd rather hand the whole record over, Full Mix + Master is me mixing your stems from scratch and mastering the result through my own chain. Every master comes with its Masterproof report, a year of Masterproof Unlimited ($120 value), and the Release Rollout Checklist. I'm biased; the free tools above get most vocals there on their own.

Quick answers

Is there a free alternative to soothe2? Not an exact one, but TDR Nova comes closest: free dynamic EQ bands that cut a harsh frequency only when it spikes. Techivation T-De-Esser 2 is a free, faster option for harshness and sibilance, and every major DAW has a stock de-esser or multiband route.

Is TDR Nova as good as soothe? On one known problem, it can sound just as transparent. What it lacks is soothe's automatic detection: you find each frequency yourself, and you get four bands instead of cuts across the whole spectrum.

Can FabFilter Pro-Q 4 replace soothe? Partly. Its Spectral Dynamics mode cuts individual peaks inside a band as they cross the threshold, which is soothe-like within the range you set. You still place the bands, and reviews say it doesn't fully replace soothe for whole-spectrum suppression.
