A limiter stops the loudest peaks from going over a set ceiling. Used lightly, it protects the sound and keeps the level steady. Used heavily, it squashes the voice and removes the life from it. The skill is in using only enough to do the job, and speech needs a gentler touch than many music presets suggest.
What a limiter actually does
A limiter reduces the gain when the signal would exceed its ceiling. The amount of reduction shows on the meter. A small amount, a few decibels on the loudest words, is normal. Large, constant reduction means the input is too loud for the setting, or the mix needs more gentle levelling first.
A starting point for speech
- Ceiling: set it a few decibels below full scale, leaving headroom for the export.
- Release: choose a moderate release that lets the voice recover between words, not one so fast it distorts.
- Gain: raise the input only until the loudest peaks touch the limiter, not beyond.
- Lookahead: use a short lookahead if the tool offers it, so the peaks are caught cleanly.
Signs you have gone too far
The voice sounds squashed or small, the breaths get louder, or the background noise rises between words. Pumping, where the level moves audibly with each word, is another sign. Reduce the gain reduction, then listen again. If the mix needs that much limiting, fix the levels earlier in the chain.
Check the export
After limiting, check the true peak and the loudness of the exported file, not only the project. The LUFS meter is useful for confirming the final level, and listening on a phone will tell you whether the voice still sounds natural.
Limits
Limiter presets are starting points, not answers. Every voice and recording is different. Use the settings as a place to begin, and adjust by ear until the voice sounds clear and natural, with only the peaks caught.

Frequently asked questions
Should I use a limiter on speech at all?
A light limiter can help, especially for protecting against peaks. Use it gently.
What does pumping mean?
The level moves audibly with each word because the limiter reacts too strongly. Use a slower release or less gain.
How much gain reduction is too much?
If the voice sounds flat or the breaths get loud, you are using too much. A few decibels on the peaks is typical.
Can a limiter make my voice louder?
It can raise the average level, but it does so by reducing the peaks. It cannot add clarity.
