Vocals Too Quiet in the Mix? How Loud Should the Vocal Sit Against the Instrumental?

Published · Updated

If the vocal in your mix feels too quiet, aim for this: a listener can follow every word without effort in the verse, still follows it in the chorus, and still follows it when playback is turned down low. To try it right now, raise the vocal 1 dB at a time until the words are easy to follow in the verse, then play the chorus and check again. There is no single number for how far above the instrumental a vocal should sit, because the right level depends on the arrangement, the genre and your taste. What works better is a repeatable way to set the level, plus a few checks for the cases where the vocal is not really too quiet, just buried. The steps below cover both, and the numbers in them are starting points to try, not standards.

Why the vocal feels quiet (it is not always the fader)

"Quiet" can mean several different things, and each one has a different fix. Before you touch a fader, play the mix and decide which of these sounds like yours:

How to set the vocal level, step by step

  1. Set up a fair listening test. Pick one playback volume and keep it for the whole session. Choose a comfortable volume rather than a loud one, because loud playback makes everything seem clear and hides balance problems. Then choose two sections to loop: a sparse one, such as a verse, and a busy one, such as the last chorus. If the vocal works in both, the rest of the song is usually close.
  2. Settle the instrumental first, then leave it alone. As a starting point, set its fader so the loudest peaks reach around -6 dBFS on the track meter (0 dBFS is the top of the meter), which leaves room for the vocal on top. From here on, move only the vocal. Changing both at once is how people lose track of what helped.
  3. Bring the vocal up until the words are effortless in the verse. Move the fader 1 dB at a time, which is a good step size to start with. Stop when you can follow every word without concentrating. If you have to strain, it needs more.
  4. Check the same setting in the busy section. If the vocal is clear in the verse but buried in the chorus, do not simply raise the whole vocal. For lines that jump around in level, see the section on line-to-line changes below. For a vocal that is loud enough but still hidden, see the section on making room.
  5. Turn the playback volume right down. At very low volume, listen to which parts are still audible. A vocal that is among the last things to disappear is usually sitting well. If the vocal vanishes first, it needs more level or more room.
  6. Compare with a reference. Choose a released song in a similar style whose vocal balance you like. For a cover, the original recording is a natural choice. Put it on its own track next to your mix, then lower the reference's track fader until it plays at about the same loudness as your mix. If your software has a loudness meter, use it to bring the two close. A louder track tends to sound better, and that would mislead you. Listen to where the vocal sits relative to the instrumental, not to how loud the whole track is.
  7. Check on other speakers. Play the mix on earbuds, a phone speaker, a laptop and, if you can, in a car. If the words stay clear on all of them, the balance is probably in good shape. If they only disappear on one, adjust a little and check again.
  8. Save a copy, rest, then listen once more. Save this version as a separate file so you can go back to it. Ears adapt, so take a break, come back, and play the whole song once from the start. Fix only what you notice on that first pass.

When the level changes from line to line

If some words are quiet and others are loud, raising the whole vocal makes the loud words too loud while the quiet ones are still behind. That is a dynamics problem, and there are two common ways to deal with it.

Afterwards, re-check the vocal level in both the sparse and the busy section, because evening out the dynamics changes how loud the vocal feels.

When turning the vocal up doesn't help

If the vocal is already loud and still does not stand out, the problem is probably that the instrumental and the voice are competing for the same space. These options work on the space rather than the level:

What "loud enough" depends on

Genre, arrangement and taste all move the answer. A sparse arrangement with a piano or a guitar lets the voice stand clearly in front. A dense, loud arrangement may keep the voice a little further inside the music, and there the work is often in EQ and effects rather than level alone. For a cover, it can help to compare with the original, at matched loudness, to see how far forward that version places the singer, then decide whether your version should do the same or something different.

If you read a decibel figure for the vocal level in a forum thread, treat it as a starting point for that person's song, not a rule for yours.

A short checklist

For people who want these steps done automatically

KUBOMI, auto-mix and mastering for cover singers, takes over one part of this job: the balance between your vocal and your backing track. The listening checks on your own speakers stay with you. You upload your vocal and backing track files in your browser (harmonies and doubles are optional), and the first version keeps your singing as it is; settings such as the vocal level let you make a new version, and earlier versions stay so you can compare and choose. You can try one song without signing in.
