Once I first began mixing, it was completely trial-and-error. I’d spend hours ironing out the vocal combine, however I didn’t know what to do concerning the annoying sibilance that was wrecking the tone.

Little did I do know de-essers might have solved this actual drawback.

That will help you keep away from my tragic destiny (of losing an excessive amount of time on every combine), I’ve put collectively this information to de-essing. By following the directions on this article, you’ll have the opportunity to squash sibilance in beneath 30 seconds.

How to Use a De-Esser Like A Professional


What Is A De-esser?

A de-esser is a easy device that goes a great distance in making your mixes sound skilled. A de-esser permits us to compress the sibilance in our vocals.

Sibilance is a sort of sound that always appears harsh within the context of a recording. Sometimes “S” and “T” are the worst offenders. The remainder of your vocal chain might sound good, however phrases like “Specialty” might sound overwhelming due to sibilance.

A de-esser permits you to isolate the frequency vary that’s inflicting probably the most sibilance. When that frequency vary will get too loud, the de-esser turns it down.

It’s primarily simply a fancy compressor that has a doctorate in excessive frequencies.

When executed appropriately, your listeners gained’t discover that your vocals are being de-essed. However the tone and quantity of the vocals will be a lot smoother due to it.

That being stated, you’ll need to keep away from getting too gung-ho when compressing, or “ducking,” sibilance. Flip it down an excessive amount of and your “S’s” and “T’s” will vanish, which can sound unnatural to your listeners.


Getting Began with Your De-Esser

You don’t want an costly plugin to get the job finished. I’ll be utilizing Logic Professional’s inventory de-esser for demonstration. However just about any DAW will include a de-esser that makes use of the identical primary features.

You’ll in all probability want to use a de-esser in four out of each 5 mixes. If you end up boosting the higher mids in a vocal, you’ll virtually definitely need to use a de-esser.

To get began, loop a few bars of the track that has a lot of sibilance. If the top of your first verse going into the refrain has a few “S’s”, set it to loop.

When you’ve discovered the part you need to loop, load in your de-esser.


Choosing The Proper Frequency

Any de-esser you come throughout could have a part the place you choose your middle frequency. That is the frequency that’s inflicting you probably the most hassle with sibilance. Often it lies someplace within the vary of 5-9 kHz.

Sibilance in males’s voices is usually on the decrease finish of this vary, round 5-6kHz. With ladies’s voices you’ll typically discover sibilance round 7-8k. This isn’t all the time the case although, so be sure to’re listening as you decide your middle frequency.

In my challenge, 8kHz was proving to be the worst offender.

Logic’s de-esser works a little totally different than most. Often de-essers solely have one part for frequency choice, however as you’ll be able to see, Logic’s has two.

The one on the left is the detector whereas on the appropriate we’ve got the suppressor. The detector is the place you select the frequency that triggers the de-esser to interact, whereas the suppressor determines which frequency is definitely being ducked.

As a basic rule of thumb, setting the detector and suppressor to the identical frequency is ok.

You need to discover the frequency that makes sibilance probably the most noticeable and set your detector and suppressor there. Fortunately, most de-essers have one other software that makes this activity easy and quick.


The Monitor

The monitor permits you to solo the frequencies you’re attenuating. In Logic, you’ll be able to solo the detector, suppressor, or sensitivity (extra on what sensitivity is later).

Soloing the detector permits you to pay attention solely to the frequency vary the detector is honed in on. By doing this, you’ll have a a lot simpler time discovering the frequencies the de-esser ought to duck.

Maybe 7k isn’t as biting as you anticipated, however as you shift the frequency vary over to 8k, you discover that the every “s” is nearly insufferable.

When you’ve discovered your drawback frequency, keep in mind to flip the monitor off once more so that you’re listening to the complete vocal sound.


Threshold (or Sensitivity)

That is the place we ensure the de-esser is simply turning down the “s” and “t” sounds which are inflicting us hassle.

Most de-essers name this the “threshold,” however Logic calls it sensitivity. Regardless, they accomplish the identical objective. If the detector and suppressor determine the place the de-esser side-chains the alerts, the sensitivity decides when.

Like the edge on a compressor, the sensitivity of a de-esser determines how loud your chosen frequency wants to be earlier than the de-esser begins turning it down.

Turning up Logic’s sensitivity setting will make the de-esser react extra. Setting the sensitivity too excessive will make it compress extra of the sign. So that you need to dial in a candy spot between “not compressing at all” and “compressing too much.”

Luckily, Logic’s de-esser makes it straightforward to see once you’re compressing the sign and if you aren’t.


Exercise Mild

There’s small circle on the best aspect of Logic’s de-esser labeled “Activity.” When the de-esser is working, this circle lights up yellow.

When setting your sensitivity, regulate the exercise circle to be sure it’s solely lighting up whenever you need it to.

If it doesn’t mild up whenever you want it to, you might want to flip the sensitivity up. If it’s lighting throughout non-sibilant phrases, you’ll need to flip the sensitivity down.



Power is the place you determine how a lot you need to attenuate the sibilants.

As you pay attention to your looped part, progressively improve the power. Sooner or later the sibilants can be too suppressed and the vocalist will begin to sound like they’ve a lisp. When you’ve discovered that spot, you’ll need to lower the power a little bit.

It’s nice to solo your vocal whereas discovering the appropriate frequency and sensitivity, however checking the power is greatest carried out in context of the combination.



Different de-esser have features comparable to this referred to as “attack.”

Like the assault on a compressor, smoothing on the Logic de-esser determines how briskly the achieve discount is. Sliding the fader to the left will make the de-esser interact faster, slicing off sibilance quicker. By sliding it to the appropriate, the de-esser will take longer to work.

As you may anticipate, you’re aiming for a good center floor when it comes to smoothing. If it’s too quick, you gained’t hear any of the “S’s” and “T’s.” Too sluggish and it gained’t do something in any respect.

The smoothing is routinely set to 10ms and I discover this to be a good start line. I often discover myself setting the smoother someplace between eight and 18ms.


However The place In The Vocal Chain Ought to I Put The De-esser?

Like many questions associated mixing, there are a number of solutions.

Wherever you place your de-esser, be sure to’re doing it deliberately. Anywhere you set it is going to change the sound of your vocal.

Right here’s what I do…

I place my de-esser after EQ and Compression, and earlier than any results.

Should you use EQ after de-essing, chances are you’ll find yourself boosting the higher mids, which is probably going to make sibilance a drawback as soon as extra. I put my EQ first, that method I haven’t wasted time on a de-esser that will not do its job as soon as frequencies have been boosted.

Compression raises the noise flooring, turning up the quietest elements of a sounds whereas turning down the loudest. This implies sibilance is probably going to sound louder after compression.

Because the sibilance is louder, it’s simpler in your de-esser to detect it. Compressing earlier than de-essing makes it simpler on your de-esser to ‘see’ drawback frequencies.

I de-ess earlier than results processors for a similar purpose I exploit EQ earlier than results. Hassle frequencies can get extra troublesome as soon as results have been utilized.

For instance, muddiness within the mid-range will simply worsen as soon as it’s been saturated. By chopping out drawback frequencies earlier within the combine chain, you make sure that your results sound as clear as potential.

Equally, by turning down sibilance earlier within the chain, you make sure that any impacts you add later don’t contribute to the issue.


Different Makes use of for a De-esser

Whereas de-essers are mostly used on vocals, that definitely isn’t the one software!

For instance, if the string noise from an acoustic guitar is just too outstanding, attempt throwing a de-esser on it. You might additionally scale back bow noise from a stringed instrument with a de-esser.

Through the use of the identical methods described above, you will discover your drawback frequency vary and switch down the offending sounds.



When utilizing a de-esser, comply with these 5 easy steps to ensure you get it proper each time.

  1. Place your de-esser after your EQ and Compression.
  2. Discover the frequency the place sibilance is most current.
  3. Set your threshold (or sensitivity) so the de-esser is just turning on when sibilance is current.
  4. Flip up the de-esser’s power till the vocalist “S’s” and “T’s” are arduous to hear. Then dial the power again a little bit.
  5. Set the smoothing so the achieve discount sounds pure, often between eight and 18 ms.
