A vocal compressor isn’t just “make it louder.” It’s the tool that decides whether your singer feels steady and intimate… or jumpy and glued to the speakers. The good news: you don’t need 15 compressors. You need two behaviors:
- The short list of vocal compressor VSTs (free + paid)
- Step 1: Decide what your vocal needs
- A) Is the problem peaks (random loud syllables)?
- B) Is the problem inconsistency (vocal disappears then jumps)?
- C) Do you want tone (thicker, smoother, more “record”)?
- Clean leveling compressors
- Character compressors
- Optical leveling vibe (classic vocal “glue”)
- Modern pop smoothness / controlled sheen
- Thick, vibey, round (vari-mu style)
- The best beginner vocal chain (works with free plugins)
- Vocal compression settings by goal
- 1) “Natural, intimate, stable” (singer/songwriter, R&B, soft pop)
- 2) “Forward and modern” (pop, rap, dense EDM)
- 3) “Aggressive and controlled” (rock, shouty vocals)

Below is a practical guide to choosing the right vocal compressor VST (free + paid), plus starter settings you can actually use.

Step 1: Decide what your vocal needs
Ask one question before touching a knob:
A) Is the problem peaks (random loud syllables)?
You need a faster compressor (peak control) or a first “catcher” stage.
B) Is the problem inconsistency (vocal disappears then jumps)?
You need leveling (slower, smoother, more constant control).
C) Do you want tone (thicker, smoother, more “record”)?
You want character compression—optical/vari-mu style behavior.
Most pro vocal chains use two stages:
Peak control → Leveling (serial compression).
Clean leveling compressors
Clean leveling is about control without obvious flavor. It’s what makes vocals feel “finished” without sounding compressed.
Best for clean leveling (free)
TDR Kotelnikov: https://www.tokyodawn.net/tdr-kotelnikov/
Use it when:
- You want transparent consistency
- You’re mixing dense productions where the vocal must stay locked
Starter settings (leveling)
- Ratio: 2:1
- Attack: 15–30 ms
- Release: 80–150 ms
- Gain reduction: 2–5 dB on loud lines
If it starts “breathing,” lengthen release or reduce GR.
Best all-around clean (paid)
FabFilter Pro-C 2: https://www.fabfilter.com/products/pro-c-2-compressor-plug-in
Why it wins on vocals:
- Multiple styles in one plugin (clean, punchy, aggressive)
- Easy sidechain filtering (prevents low-end from over-triggering)
- Fast A/B workflow
Starter settings (modern pop/rap vocal control)
- Ratio: 2:1 to 4:1
- Attack: 10–25 ms
- Release: 60–120 ms
- GR: 3–6 dB on peaks / loud phrases
Character compressors
Character compression changes tone: it can feel thicker, smoother, more forward—even at similar gain reduction.
Optical leveling vibe (classic vocal “glue”)
UAD LA-2A Collection: https://www.uaudio.com/uad-plugins/compressors-limiters/teletronix-la-2a-collection.html
Use it when:
- You want smooth, natural leveling
- You want that “vocal sits in the track” feel without sharp pumping
How to set it (simple)
- Adjust gain reduction until you see 2–5 dB most of the time
- If it’s too slow to catch peaks, put a fast compressor before it
Modern pop smoothness / controlled sheen
Softube Tube-Tech CL 1B: https://www.softube.com/tube-tech-cl-1b
Use it when:
- You want polished control without making the vocal feel small
- You’re chasing that “expensive” pop vocal density
Thick, vibey, round (vari-mu style)
Klanghelm MJUC: https://klanghelm.com/contents/products/MJUC
Use it when:
- You want weight and smoothness
- You want compression that feels like it’s part of the tone
The best beginner vocal chain (works with free plugins)
Chain: DC1A → Kotelnikov
- Klanghelm DC1A as a peak catcher
https://klanghelm.com/contents/products/DC1A- Aim: 1–3 dB GR on the loudest hits
- Keep it subtle: you’re just shaving spikes
- TDR Kotelnikov as the main leveler
https://www.tokyodawn.net/tdr-kotelnikov/- Aim: 2–5 dB GR for consistency
This two-step setup often sounds more natural than trying to do everything with one compressor.
Vocal compression settings by goal
1) “Natural, intimate, stable” (singer/songwriter, R&B, soft pop)
- Ratio: 2:1
- Attack: 20–35 ms
- Release: 90–180 ms
- GR: 2–4 dB
Best tool: Kotelnikov (free) or Pro-C 2 (paid)
2) “Forward and modern” (pop, rap, dense EDM)
- Ratio: 3:1–4:1
- Attack: 10–20 ms
- Release: 50–120 ms
- GR: 4–7 dB
Best tool: Pro-C 2, or CL 1B style for polish
3) “Aggressive and controlled” (rock, shouty vocals)
- Ratio: 4:1–6:1
- Attack: 5–15 ms
- Release: 60–140 ms
- GR: 5–10 dB (depends on style)
Tip: Use two compressors instead of crushing one.
Why your vocal sounds worse after compression (and fixes)
- Sibilance gets louder → compression pushes “S” forward
Fix: use dynamic EQ / de-essing before or after compression. - Vocal gets smaller/duller → attack too fast or too much GR
Fix: slow attack, reduce GR, lower ratio. - You hear pumping → release too fast or threshold too low
Fix: lengthen release, reduce GR, or use serial compression. - Vocal still jumps out randomly → single compressor doing too much
Fix: add a gentle peak catcher first (DC1A), then level.
