Testimonials
Tips
- I start with the T-De-Esser turned off so I can hear the original sound first.
- I turn on the Filter mode to hear the high sounds being detected. This helps me choose the right frequency range.
- I slowly raise the Processing control until harsh “s” sounds or sharp tones begin to soften.
- I use a low Intensity setting first. Too much compression can make a voice sound dull or lispy.
- I compare the processed sound with the bypassed sound often. The goal is to reduce harshness without changing the whole tone.
- Match the output level before and after processing. A louder signal can seem better even when it is not.
- Use automation when only a few words or notes are harsh. This keeps the rest of the performance more open and natural.
2. TDR Nova
OS: Windows Win Mac Mac Linux Linux Bit Version: 32-bit, 64-bit Developer: Tokyo Dawn Records Size: 8 MB Rating: 87/100
TDR Nova is a parallel dynamic equalizer with four adjustable bands, high-pass and low-pass filters, and visual frequency feedback. Each band combines EQ and dynamics controls for tasks such as tone shaping, de-essing, frequency-focused compression, multiband processing, and broad compression.
Its graph and knob controls provide access to frequency, gain, threshold, ratio, attack, release, and mix settings. Presets, undo and redo, A/B comparison, solo, external sidechain, and equal-loudness tools support work on tracks, buses, and masters.
Features
- Parallel Dynamic Equalizer
- Four Dynamic Equalizer Bands
- Frequency-Selective Compression
- Multiband Compression Processing
- Wideband Compression Processing
- Drag-And-Drop Frequency Display
- Visual Spectrum Feedback
- Adjustable Attack And Release
- Adjustable Threshold And Ratio
- External Signal Control
Pros
- 4 Bands target problem sounds
- Dynamic cuts sound more natural
- Also works as a regular EQ
- Handles compression and tone shaping
- Includes high-pass and low-pass filters
- Built-in analyzer shows frequency problems
- Band solo helps find harsh sounds
- GR Delta reveals removed sound
- External sidechain adds extra control
Cons
- Needs manual frequency hunting
- No automatic sibilance detection
- Steeper learning curve
- Many controls feel overwhelming
- May affect nearby vocal tones
- Can miss changing sibilance
Testimonials
Tips
- I start by finding the harsh or muddy sound before changing any controls. This helps me use TDR Nova to fix a real problem instead of changing the whole mix.
- I turn on the dynamic section when I want a sound to change only when it gets too loud. This works well for harsh vocals, boomy bass, and sharp cymbals.
- I lower the threshold until the band reacts only to problem sounds. If the gain reduction happens all the time, I raise the threshold.
- I use a medium attack and release first when setting up a de-esser. Then I adjust them so the “S” sounds are reduced without making the voice dull.
- I check the result with equal loudness bypass. This keeps a louder setting from tricking me into thinking it sounds better.
- I use a small amount of gain reduction on most vocals. Gentle control often sounds more natural than removing every “S” sound.
- Set the band frequency where the “S,” “T,” or “SH” sounds are strongest. Many voices need control in the upper-mid or high-frequency range, but every voice is different.
3. SweetVox
OS: Windows Win Mac Mac Bit Version: 64-bit Developer: Analog Obsession Size: 4.5 MB Rating: 79/100
SweetVox is a clean vocal-processing plugin designed to reduce harsh sounds, sibilance, and excessive low-end buildup. It uses three fixed EQ bands, two dynamic EQ bands, and a built-in de-esser to shape vocals with controlled, natural results.

Pros
- Simple all-in-one vocal channel strip
- Includes two dynamic EQ bands
- Includes three fixed EQ bands
- Adds optional saturation for warmth
- Includes compression when needed
- LED lights show processing levels
- Real-time monitoring guides adjustments
- Mix control blends processed sound
- Output control prevents volume jumps
- Supports VST and AU formats
Cons
- Only one main de-esser control
- No adjustable detection frequency
- No attack or release controls
- No adjustable threshold control
- No selectable processing modes
- De-esser can sound too hard
- Strong settings may remove highs
Testimonials
Tips
- I watch the de-esser reduction meter while the singer says words with “S” and “T” sounds. I lower the threshold until the sharp sounds become smoother.
- I use the BAND button when only a small area of the voice needs control. The normal setting can work well when the whole top end feels too bright.
- I adjust the release time so the vocal does not sound like it is lisping. A faster release may work for quick words, while a slower release can sound smoother.
- I use the MIX control to blend some untreated vocal back into the sound. This helps me keep the voice natural while still lowering harsh “S” sounds.
- I compare the processed vocal with the bypassed sound at the same loudness. This helps me choose settings that truly improve the voice.
- A de-esser should reduce harsh sounds, not remove all high frequencies. Too much reduction can make a vocal sound dull or lispy.
- SweetVox works best when settings are changed while the full song plays. A soloed vocal may sound good alone but become too dark or too thin in the mix.
4. SweetVox
OS: Windows Win Mac Mac Bit Version: 64-bit Developer: Analog Obsession Size: 4.5 MB Rating: 78/100
SweetVox is a vocal processor that combines fixed-band EQ, dynamic EQ, de-essing, saturation, and compression to shape vocal recordings. It helps reduce harsh sibilance, boominess, and other unwanted tones with simple Process and Output controls.

Testimonials
Tips
- I use the bypass button often to compare the dry and processed vocal. If the change is too large, I lower the processing amount.
- I use the de-esser only as much as needed. Too much can make words sound dull or give the singer a lisp.
- I listen to the loudest “S” sounds when setting the de-esser. These sounds show whether the plugin is working well.
- I check the vocal in the full mix, not only when it is soloed. A setting that sounds good alone may make the vocal too dark with the music.
- Set the de-esser threshold so it reacts mainly to sharp consonants. A threshold that is too low may affect normal vowels and breaths.
- Keep an eye on the reduction meter. A small amount of gain reduction is often enough for a clean and natural result.
- Use clip gain to lower only a few very loud “S” sounds before the plugin. This lets the de-esser work more gently on the rest of the track.
5. DeBess
OS: Windows Win Bit Version: 64-bit Developer: AirWindows Size: 355 KB Rating: 76/100
DeBess is a de-esser for reducing harsh “S” sounds in vocal tracks. Its detection system focuses on ess sounds while leaving other high-frequency content mostly unchanged. A variable control adjusts how narrowly it identifies and reduces these sounds.
The plugin includes controls for intensity, sharpness, depth, filtering, and detection level. Use the filter to choose the high-frequency range being processed, then adjust the other sliders to match the vocal. DeBess is available as a free 64-bit VST for Windows.

Testimonials
Tips
- I start with a small amount of DeBess and raise it slowly until the “S” sounds become smoother.
- I listen to the full vocal, not just the loud “S” sounds, so the voice still sounds clear and natural.
- I use the sample window slider to choose how closely DeBess looks for sibilance. A higher setting can help isolate “S” sounds more strongly.
- I use the filter control to shape the “S” sounds instead of making the whole vocal too dark.
- I compare the sound with DeBess on and off at the same volume. This helps me avoid choosing the louder setting by mistake.
- I use clip gain on very harsh words when one or two sounds need extra help. This lets DeBess work less on the rest of the track.
- A light setting often sounds more natural than a heavy setting that makes the singer sound like they have a lisp.
6. LOADES
OS: Windows Win Mac Mac Bit Version: 64-bit Developer: Analog Obsession Size: 9 MB Rating: 74/100
LOADES is a smooth de-esser from Analog Obsession that reduces harsh high frequencies in vocals, cymbals, and full mixes. It can also act as a high-frequency tamer, helping create a warmer sound without focusing only on vocal sibilance.
Its threshold, release, band, and soft controls shape the response, while Mix blends clean and processed signals. Input and Output offer level control, and meters show reduction and output levels. LOADES runs on Windows and Mac in VST and AU formats.
Features
- Smooth Vocal De-Essing
- Reduces Harsh High Frequencies
- Works On Cymbals

Testimonials
Tips
- I start with the Threshold control set high, then lower it until the “S” sounds become softer. This helps me avoid removing too much life from the voice.
- I watch the Reduction Level meter while I adjust the plugin. I usually aim for light gain reduction instead of heavy processing.
- I use the Band button when I want LOADES to focus more closely on the sharp “S” sounds. Without it, the de-esser uses a wider shelf-style reduction.
- I try the Soft button when the normal setting sounds too strong. It gives slower action and a lower ratio for a smoother sound.
- I set the Release control so the voice returns to normal quickly after each “S.” If the release is too slow, the voice may sound dull.
- I use the Mix control to blend the treated sound with the dry sound. This lets me keep some natural brightness in the voice.
- I compare LOADES on and off at the same volume. This helps me tell if the sound is truly better or only louder.
7. Lisp
OS: Windows Win Bit Version: 32-bit, 64-bit Developer: Sleepy-Time DSP Size: 1 MB Rating: 70/100
Lisp is a free Windows VST de-esser that detects and reduces vocal sibilance, including harsh “s,” “t,” and “ch” sounds. Its level-independent design uses pitch, amplitude, and frequency tracking to keep voices clear while processing complex vocal tracks in real time.

- Can sound artificial sometimes
Testimonials
Tips
- I start with Lisp in Auto Mode so it can find changing “S” sounds for me. This is a good place to begin when I am new to the plugin.
- I raise the Reduction control slowly until harsh “S” sounds become softer. Lisp can reduce sibilance by up to 20 dB, so small changes are best.
- I use the Listen button to hear what Lisp is removing. This helps me make sure it is reducing “S” sounds instead of parts of the voice.
- I turn down Sensitivity if Lisp reacts to too many sounds. I turn it up when strong “S” sounds are not being caught.
- I adjust the Attack and Release controls to make the effect sound smooth. A faster attack catches sharp sounds, while a longer release can sound more natural.
- I compare the treated sound with the bypassed sound often. If the voice loses too much life, I lower the Reduction or Sensitivity.
8. Airwindows DeEss
OS: Windows Win Bit Version: 64-bit Developer: AirWindows Size: 344 KB Rating: 69/100
Airwindows DeEss is a de-essing plugin that detects sharp “s” sounds by tracking changes in the audio signal. It reduces harsh vocal and instrument sounds while helping preserve the original tone.

Testimonials
Tips
- I start with a clear vocal track so I can hear the “S” sounds before adding DeEss.
- I raise the Intensity control until the plugin reacts to sharp “S” sounds, but not to every bright sound.
- I use MaxDeEss to choose how much the harsh high sound is lowered. I stop before the voice starts to sound dull.
- I adjust Frequency to decide how much of the voice gets reduced. A higher setting usually keeps more of the vocal body.
- I listen to the full mix, not just the solo vocal, because a small change may sound better with the music.
- I compare the plugin on and off at the same volume. This helps me avoid thinking that a louder sound is always better.
- A de-esser should reduce harsh sounds, not remove all brightness from the voice.
9. BLOCKFISH
OS: Windows Win Bit Version: 32-bit Developer: Digitalfishphones Size: 0.6 MB Rating: 69/100
BLOCKFISH is a versatile compressor with countless ways to shape incoming audio. It likes to bite, but it can be tamed easily once you’ve learned how to use its potential. Its removable panel reveals extra circuit controls for transparent, punchy, smooth, or saturated results.

Testimonials
Tips
- I use the plugin as a de-esser by focusing on harsh “s” and “sh” sounds. A gentle setting can reduce these sounds while keeping the voice bright.
- I use a narrow frequency range to target only the harsh sounds. Common problem areas are often found in the upper middle or high frequencies.
- Solo the problem frequency for a short time while setting the de-esser. Turn solo off often to check how the full mix sounds.
- Listen for dullness when using a de-esser. Too much reduction can remove the natural brightness and detail from a voice.
- Place a de-esser after heavy vocal compression when new harsh sounds appear. Compression can bring hidden “s” sounds forward.
- I adjust the release time until the sound feels natural. If the release is too fast, I may hear pumping or wobbling.
- I compare the processed sound with the bypassed sound often. I make sure the plugin improves the track instead of only making it louder.
10. Tonmann DeEsser
OS: Windows Win Bit Version: 32-bit Developer: Tonmann Size: 1.5 MB Rating: 68/100

Testimonials
Tips
- I start with a vocal part that has clear “S,” “SH,” and “T” sounds. This helps me hear what the Tonmann DeEsser needs to fix.
- I use the “What You Remove” listen mode to hear the sound being reduced. I adjust the controls until I mostly hear harsh sibilance, not the full vocal.
- I slowly move the center frequency until the harsh “S” sounds become clear. Then I set the bandwidth wide enough to catch the problem but not the whole vocal.
- I lower the threshold until the plugin reacts only when sibilance gets too loud. If it works all the time, I raise the threshold.
- I begin with light attenuation, such as 2 to 4 dB. Too much reduction can make the singer sound dull or create a lisp.
- I compare the processed sound with the bypassed sound often. The goal is to make the vocal smoother, not to remove every “S” sound.

Testimonials
Tips
- I lower the threshold slowly until the harsh sounds become softer. I stop before the vocal starts to sound dull or lispy.
- I listen to the vocal with the De-Esser on and off. This helps me make sure the plugin is helping instead of changing the whole voice.
- I use a small amount of processing first. Light de-essing often sounds more natural than heavy processing.
- I place the De-Esser after basic EQ when EQ makes the high end too sharp. This can help control extra brightness added by the EQ.
- I try the plugin before compression if strong “S” sounds make the compressor work too hard. This can give the compressor a smoother signal.
- Use the De-Esser while listening to the full mix, not only the solo vocal. A setting that sounds good alone may make the vocal disappear in the song.
- Match the output level after processing. The track should not become much louder or quieter just because the plugin is active.

Testimonials
Tips
- I start by turning on Listen so I can hear the harsh “s” sounds the plugin is targeting. This helps me avoid removing too much of the voice.
- I slowly move the Tune control until I find the sharpest part of the “s” sound. Different voices may need different settings.
- I raise Sense until Spitfish reacts mostly to “s,” “sh,” and “ch” sounds. If it reacts to every word, I lower the setting.
- I turn up Depth little by little until the harsh sounds are softer. Small changes often sound more natural than large ones.
- I compare the processed sound with the original by using Bypass. The goal is to reduce harshness without changing the whole voice.
- I use less de-essing before compression because compression can make “s” sounds louder. I check the track again after compression and adjust if needed.
- Check for a lisp after processing by listening to words with many “s” sounds. If those words lose their clear shape, reduce the depth or sense.

- I adjust the release until the vocal sounds smooth. If the release is too fast, the vocal may sound jumpy.
- I compare the plugin on and off at the same volume. This helps me avoid thinking that a louder sound is better.
- I check the vocal after compression because compression can make “S” sounds louder.
- I listen to the vocal with the full mix, not only by itself. A small amount of sibilance may sound natural in the song.
- Use the bypass button often while making changes. The best setting should sound smoother, not lifeless.

Testimonials
Tips
- I use VeeDeeS on vocal tracks to reduce sharp “S,” “Z,” and “SH” sounds. It works by turning down some high frequencies when those sounds get too strong.
- I start with light settings and increase the effect slowly. Too much de-essing can make the singer sound like they have a lisp.
- I listen to the vocal in the full mix, not only by itself. A setting that sounds strong alone may sound right with the music.
- I adjust the release control so the vocal returns to normal after each sharp sound. A release that is too long may make the vocal sound dull.
- I compare the sound with VeeDeeS on and off often. This keeps me from removing more high end than the vocal needs.
- I use clip gain before the plugin when only a few words are too sharp. Lowering those words first can make the de-esser work more smoothly.
- I check the vocal after compression because compression can make “S” sounds stand out more. I may add VeeDeeS after the compressor for better control.

What Is A De-Esser Plugin?
A De-Esser plugin is an audio filter that reduces the level of sibilance in vocals and other sources. This type of filter is often used to reduce the popping sounds when someone says words with a “p” or “b”. It is also used to reduce “s”, “z”, “ch”, and “sh” sounds from vocals.
De-esser plugins reduce high frequencies, typically between 8 and 16 kHz, which are known to cause the “S” and “T” sounds to become excessively harsh. De-esser plugins detect peaks in the frequency spectrum and remove those peaks with a downward slope. De-Essers Explained
What Is The Best Free De-Esser?
The best free De-Esser plugins are “Lisp” by Sleepy-Time DSP, “DeEss” by Airwindows, “Tonmann DeEsser” by Tonmann, “Spitfish” by Digitalfishphones, and “VeeDeeS” by Viper ITB. These de-essers offer tons of flexibility and features for free.
What Is A De-Esser Plugin Used For?
A de-esser plugin is an audio processing plugin that can be used to reduce the volume of the sibilant sounds in a source signal. Sibilant sounds are consonants that have a high frequency, such as “s”, “sh”, and “ch”. A de-esser plugin can be used to reduce the hissing and popping noises found in audio.
What Is the Best De-Esser Plugin?
The best de-esser plugins are “Sibilance” by Waves Audio, “FabFilter Pro-DS” by FabFilter, “IQ-Series DeEsser” by HOFA, “Oxford Supresser” by Sonnox, and “SPL De-Essers” by Brainworx Audio. These are the top-paid de-essers with professional features.
Do I Need A De-Esser?
You might need a de-esser if you notice any harsh sibilant sounds in your audio recordings. These sharp, hissing sounds are typically caused by the letters S, T, and Z, and they can make your recordings sound harsh and unpleasant.
A de-esser can help to reduce or eliminate these sounds, making your recordings sound smoother and more pleasant. De-essers work by analyzing the audio signal and reducing the level of the offending frequencies when they detect sibilance.
This can help to greatly improve the overall quality of your recordings, making them sound more professional and polished. That’s why de-essers are essential for any audio engineer or music producer.
What Is Sibilance?
Sibilance is the harsh, hissing sound created by certain letters and combinations of letters when they’re pronounced. The letters S, Z, SH, CH, and J are the most common sources of sibilance.
Sibilance can be a problem when recording or broadcasting audio because it can make speech difficult to understand. It can also be distracting to listeners. In some cases, it can even be painful to listen to.
That’s why many broadcasters and voice-over artists try to avoid sibilant sounds whenever possible. To avoid sibilance, they might use a de-esser, a type of audio processing plugin that can reduce or eliminate the harsh, hissing sounds of sibilance.
What Frequency Should I Set De-Esser?
The frequency you set your de-esser will vary depending on the singer’s voice and the type of de-esser you’re using. You’ll want to start by listening to the singer’s voice and finding the frequency range with the most sibilance. Then, set your de-esser to that same frequency range.
If you’re unsure where to start, try somewhere between 4kHz and 9kHz. This is because most sibilant sounds fall within this frequency range. A male singer will typically have more sibilance in the lower end of this range, while a female singer will have more sibilance in the upper end.
How To Use A De-Esser?
De-essing is typically done by using a multiband compressor to split the signal into multiple frequency bands and then compressing those bands independently. This allows the compressor to target only the frequencies that contain sibilance without affecting the rest of the recording.
There are many different ways to set up a de-esser, but you will generally want to start by splitting the signal into two or three frequency bands. Then, set the threshold and ratio for each band to compress only the frequencies containing sibilance.
Finally, adjust the attack and release times so that the de-essing is subtle and not too noticeable. If done correctly, de-essing can make a huge difference in the quality of your recordings.
Where to Put a De-Esser in a Chain?
It’s a good idea to put it early in the chain so that any following processing doesn’t amplify the esses. For example, if you have a very ‘s’ sounding recording, putting a de-esser before your EQ will help tame some of that sibilance.
But there’s no definitive answer to where to put a de-esser in your signal chain, as it will depend on the audio issue you’re trying to address.
How Do You De-Ess Vocals?
There are a few different ways to de-ess vocals. One common practice is using a spectral editor like iZotope RX to identify and attenuate the sibilance using a multiband EQ manually. This can be time-consuming, but it can be very effective. Another option is to use an automated de-essing plugin, like Waves SIBilance.
These de-essers analyze the audio signal and dynamically attenuate the sibilant frequencies. This can be very effective, but it can sometimes result in artifacts if the plugin is overly aggressive.
The third option is to use a noise gate with high thresholds and short release times to effectively mute the sibilant sounds while allowing the rest of the vocal recording to come through.
De-Esser Explained
De-Esser plugins are audio plugins that are designed to reduce the sibilant frequencies in vocals and other sources.
Our final thoughts are that there are tons of free de-esser VST plugins that you can use without spending money. These de-essers are great free alternatives to T-De-Esser Pro, Accusonus ERA De-Esser Plug-in, Waves De-Esser, Brainworx SPL De-Esser Collection, IK Multimedia De-Esser, and FabFilter Pro-DS.
Paid plugins like the Accusonus Era De-Esser and the Fabfilter Pro-DS offer single-band de-esser controls and modern dual-band versions similar to analog hardware de-essers.
I hope you find these free de-esser plug-ins helpful. These de-essers are great for whether you are a mixing engineer, podcaster, or anyone working with vocal tracks.
