What it is and how it differs from the master limiter
A limiter is a compressor with a very high ratio (from 10:1 to ∞:1) and an almost instantaneous attack, often with look-ahead (the plugin “looks ahead” a few milliseconds and lowers the gain before the peak arrives). On the master it sets the ceiling and the final loudness (see “Limiter and true peak”). On tracks and buses it has different jobs:
- Trimming isolated peaks that the compressor does not catch (a screamed syllable, a louder snare hit, the initial peak of an 808).
- Protecting a bus from peaks that would drive the following processors into saturation.
- Density and character: a pushed limiter on a drum bus or an 808 increases perceived sustain and density, like a very fast compressor.
- Controlling the level of a layer (e.g. a clap on top of the snare) so that it never exceeds a certain value.
Parameters
- Ceiling / output: the maximum output level. On tracks and buses you do not need a ceiling of −0.1 dBFS: set the ceiling at the working level (e.g. −6 dBFS) and adjust the input.
- Threshold or input gain: how hard you push into the limiter. On a track 1–3 dB of reduction on the peaks; for density 3–6 dB.
- Release: 10–50 ms for short peaks (drums), 50–200 ms for vocals and bass. Automatic (program-dependent) releases are a good starting point.
- Look-ahead: 1–5 ms. Higher = more transparent on peaks but more latency and blunted attacks. On drum transients keep it low (0.5–1 ms) if you want to preserve the click.
- Style / algorithm (in FabFilter Pro-L: Transparent, Punchy, Dynamic, Allround, Aggressive, Modern, Safe): Transparent and Safe for control, Aggressive for density.
- Channel link: on a stereo bus keep it at 100% (or close) so as not to shift the image.
Limiter or clipper?
- The clipper instantly cuts the waveform: it adds harmonics, preserves the perceived attack, and has no release. Great for very short peaks (kick, snare, 808).
- The limiter lowers the gain with an envelope: no direct distortion if used in moderation, but it attenuates the transient and, when pushed, produces pumping.
- Rule of thumb: on drums, clipper for the first 1–3 dB; on vocals, bass and mixed buses, limiter.
Starting settings
| Source | Reduction | Release | Notes |
|---|---|---|---|
| Lead vocal (after the compressors) | 1–2 dB on the peaks | 50–100 ms | Constant level for the final riding |
| Rap vocal with screamed ad-libs | 2–3 dB | 30–60 ms | Together with 1176 compression |
| 808 | 1–3 dB | 20–50 ms | Trims the initial peak, raises the sustain; clipper as an alternative |
| Drum bus | 1–3 dB | 10–30 ms | Low look-ahead, Punchy style |
| Instrumental bus (beat) | 1–2 dB | auto | Prepares the instrumental for the vocal |
| Backing vocal bus | 1–2 dB | 50–100 ms | Harmony peaks under control |
| Heavily processed effect returns | 2–4 dB | auto | Keeps delay throws from exploding |
In FL Studio
- Fruity Limiter in LIMIT mode: Ceil, Gain, Sustain (limiter release) and Knee. For a track limiter: Gain +2/+4 dB, Ceil −6/−3 dB, Sustain 10–50 ms; then lower the fader.
- Maximus as a single-band limiter: more transparent, with look-ahead and visible curves.
- Fruity Soft Clipper for the “clipper” version.
- External plugins: FabFilter Pro-L, Waves L1/L2, Kazrog KClip (clipper), LoudMax (free).
Common mistakes
- A limiter on every track “just in case”: a flat, fatiguing mix with no dynamic breathing.
- Using the limiter instead of the compressor: the limiter does not shape the sound, it only trims the peaks.
- Ceiling at −0.1 dBFS on every track: it breaks the gain staging and the mix bus saturates.
- Long look-ahead on drums: soft transients and a loss of punch.
- Limiting the drum bus and then the master again with 6 dB: a double loss of transients.
Starting settings
| Parameter | Value | Why |
|---|---|---|
| Reduction on a track | 1–3 dB on the peaks | Control without losing dynamics. |
| Reduction for density | 3–6 dB | More sustain on 808 and drum bus. |
| Drum release | 10–30 ms | Quick recovery between hits. |
| Vocal and bass release | 50–200 ms or automatic | No distortion on low frequencies. |
| Look-ahead | 0.5–5 ms | Low on drums, higher on vocals and buses. |
| Ceiling on a track | Working level (−6/−3 dBFS) | Preserves the gain staging. |
| Channel link on a bus | 100% | Stable stereo image. |
Frequencies to watch
| Range | What to do |
|---|---|
| 30–80 Hz | Initial peak of the 808 and kick: fast limiter or clipper, release 20–50 ms. |
| 2–5 kHz | Drum attack: low look-ahead so as not to blunt it. |
| 5–9 kHz | A limiter on a vocal without a de-esser exaggerates the sibilance proportionally. |
Example chain
| Step | Tool | Settings | Why |
|---|---|---|---|
| Compression | Fruity Compressor / 1176 / LA-2A | 4–8 dB overall | Shape and level. |
| De-esser | Dedicated de-esser | 5–9 kHz | Before the limiter. |
| Track limiter | Fruity Limiter / Pro-L | 1–3 dB, release 50–100 ms | Residual peaks. |
| Fader | Mixer | Level in the mix | The limiter does not replace balancing. |
How to check the result
- Crest factor of the track after the limiter: drums not below 10 dB, vocals not below 7 dB, 808 not below 5 dB.
- Track sample peak equal to the set ceiling (the limiter is working) but short-term loudness not raised by more than 1–2 LU compared to the bypass.
- Bus: correlation unchanged with and without the limiter (stereo link set correctly).
- No audible distortion in the Sub and Bass bands on 808 and bass (release not too fast).
