2. Presence and loudness

What happens to the vocal as the LUFS go up, how to keep the limiter from burying it, and when it's time to go back to the mix.

The louder the master, the harder the limiter works, and the more the vocal’s place changes. So loudness isn’t a separate decision: it’s worth evaluating it by watching whether the vocal stays in its place.

Limiter

Limiter (brickwall)stock Studio One Pro 4

Studio One's brickwall limiter. Raises the perceived level of the song and stops the peaks so nothing goes over the output ceiling.

The Limiter is an extreme compressor (ratio ∞:1) that acts as a wall: no sample goes over the ceiling you set. It’s used at the end of the master chain to raise the perceived level of the song without the peaks clipping.

What it’s for

Threshold / Gain: how hard you push the signal against the ceiling. More push = louder and denser, but past a certain point distortion appears and the song gets “crushed”.
Ceiling (Output): the real output ceiling. For streaming it’s usually left at −1 dBTP to respect the true peak after conversion.

Where you’ll use it

On the master bus (Main channel), as the last insert, over the finished mix. It’s not a mix or per-track plugin: if you’re using it to “fix” a guitar, you’re in the wrong place. It’s one of the things left for the end, once the balance is already solved.

The numbers

LUFS (perceived loudness)for rock and metal, −10 to −8; to start, −10

Platforms normalize, so louder doesn't mean it sounds louder on Spotify. If the vocal loses clarity when you push the limiter, you've gone too far: back off a little.

True peak−1 dBTP at most

It prevents distortion when converting to compressed formats. Sibilance and strong consonants can generate high peaks, so it matters on the vocal too.

Limiter reductionup to 3 or 4 dB on peaks

Beyond that, everything starts dropping with each drum hit, and the vocal goes up and down with it. It's the pumping that makes the voice seem to breathe oddly.

How to evaluate it

Match the volumes of the mix and the master before comparing.
Listen to the chorus: it’s where the limiter works hardest.
Pay attention to the lyrics: can they be understood as well as in the mix?
Pay attention to the sibilance: does it bother you more than before?

The master’s brightness

If the chain includes a high-frequency boost above 10 kHz, listen to the vocal first. If the sibilance starts to hurt, take off half a dB, or go back to the mix and adjust the de-esser.

When to go back to the mix

🔴 Set this NOW· in mastering

Correcting the vocal with the master's EQ affects the whole band. If the problem is only in the vocal, going back to the mix costs less and sounds better.

The vocal ended up low: use the version with the vocal 1 dB higher.
The sibilance hurts: adjust the vocal’s de-esser and export again.
The limiter makes it pump: check the kick and snare peaks in the mix.

If it takes more than 2 or 3 dB of EQ in the master to fix something on the vocal, the problem isn’t in the master.

Common mistakes

What NOT to chase yet

Quick path: loudness with the vocal in mind

Quick path

Ceiling at −1 dBTP and aim for −10 LUFS.
Up to 3 or 4 dB of reduction on peaks.
Match the volume and compare with the mix.
Listen to the chorus: can the lyrics be understood?
If the vocal ended up low, use the version with 1 dB more.
If the sibilance bothers you, go back to the de-esser in the mix.

Expected result

A master loud enough to compete, with the vocal as clear as in the mix, no harsh sibilance and no pumping. There’s one last step: the final check.
