How to De-Ess Vocals in Logic Pro with DeEsser 2
June 19, 2026 - 6 min read
What does DeEsser 2 do to harsh vocals in Logic Pro?
DeEsser 2 turns down sibilance: the sharp “s,” “sh,” “ch,” and sometimes “t” sounds that jump out after EQ and compression. It is not a general brightness remover. It should catch harsh consonants while leaving the vocal's air and emotion intact.
This matters because the usual bedroom-producer move is to add a high shelf, get excited for five seconds, then realize every “sss” now feels like it is two inches from the listener's face. Cutting all the highs fixes the pain but kills the vocal. De-essing is the middle move: keep the expensive top end, control the needles.
Where should DeEsser 2 go in a vocal chain?
Put DeEsser 2 after the main Compressor in most Logic Pro vocal chains. Compression evens the performance, but it also raises quiet sibilance and makes harsh consonants more obvious. De-essing after that first leveling stage catches the problem when it is actually audible.
A practical order is Channel EQ cleanup, Compressor, DeEsser 2, tone EQ, then reverb and delay on sends. If the tone EQ adds a big air shelf around 10-12 kHz and the vocal gets spitty again, add a second DeEsser 2 after the air boost doing only 1-2 dB of reduction. Two gentle de-essers usually sound more natural than one plugin trying to punish every consonant.
What frequency should I set DeEsser 2 to for vocals?
Start between 5 and 8 kHz. Male vocals often trigger lower, around 4.5-6.5 kHz; brighter pop vocals often trigger higher, around 7-9 kHz. Play the harshest line on loop and move the frequency until DeEsser 2 reacts mostly to the ugly consonants.
Do not set the frequency by looking at a chart and leaving. Use your ears. If the de-esser grabs too much of the vocal tone, the band is probably too low or the sensitivity is too high. If the sibilance still stabs through, the band may be too high, too narrow, or not sensitive enough. A good starting target is 2-5 dB of reduction only when the harsh syllables hit. The meter should move on problems, not dance through the whole sentence.
How do I de-ess without making the singer sound lispy?
Back off as soon as the front of words starts disappearing. A lispy vocal means DeEsser 2 is reducing too much, too often, or too low in frequency. Raise the frequency slightly, lower the sensitivity, and compare bypassed at the same volume.
The fastest ear check is a phrase with repeated s sounds. Bypass should feel sharp; active should feel controlled. If active feels darker, smaller, or like the singer changed their mouth shape, you went too far. Also check the vocal in the full mix. A tiny bit of sibilance can help intelligibility once drums and guitars are playing. The goal is not zero sibilance. The goal is no painful sibilance.
How do I stop reverb and delay from spreading sibilance?
De-ess before the send, then filter the effect return. If bright s sounds hit ChromaVerb or Tape Delay, the reverb tail repeats the problem. Put Channel EQ on the reverb or delay aux and roll off lows below 180-250 Hz and highs above 7-9 kHz.
This is especially important on airy pop vocals. A lead can have a beautiful 12 kHz shelf and still use a darker reverb. The dry vocal gives the detail; the effects give depth. If the space is bright enough to pronounce every “s” after the singer already stopped, it is not space anymore. It is a tiny haunted sprinkler system. Turn it down and filter it.
Can I start with a de-essed Logic Pro preset and tweak it?
Yes, as long as you treat the preset as a starting chain, not a finished law. Load the chain, loop the harshest lyric, and adjust DeEsser 2 for your voice. Sibilance changes with the singer, mic, distance, and how much air EQ the chain adds.
If you want that faster starting point, use the Logic Pro channel-strip guide to load a .cst, thenaudition MixPreset vocal chains before spending a credit. Every chain uses stock Logic plugins only, and new accounts get one free credit. For the full chain around the de-esser, keep the Logic Pro vocal mixing guide open and tweak DeEsser 2 after the first compressor.
