Vocals Too Quiet in the Mix? How Loud Should the Vocal Sit Against the Instrumental?
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:
- The level is too low. The vocal sits behind the instrumental from the first line to the last. The fix is level, and the steps in the next section handle it.
- The words get lost in busy parts. The vocal is fine in the verse but disappears in the chorus, where guitars, synths or drums fill the same range as your voice. This is a space problem, not a level problem.
- Some lines are quiet and others jump out. The singing itself varies from phrase to phrase, so no single fader position suits every line.
- The effects push the voice back. A lot of reverb or echo makes a voice sound farther away from the listener, even at the same level.
- It only sounds quiet on some speakers. The balance can be fine on your headphones and weaker on a phone speaker or in a car.
How to set the vocal level, step by step
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Level automation or clip gain. Raise the quiet words and the trailing ends of phrases, and lower the words that jump out. Where to do it (menu names can differ between versions):
- Audacity: choose the Envelope Tool on the Tools Toolbar, click the track to add control points, then drag them up or down. For a whole phrase, select it and use Effect > Volume and Compression > Amplify, and type a gain in dB. Some effects in Audacity, such as EQ, can remove an envelope, so do your EQ first.
- GarageBand (Mac): choose Mix > Show Automation (or press A), open the Automation Parameter pop-up menu in the track header and choose Volume fader. Click the curve to add points, then drag them up or down.
- REAPER: select the track and press V to show its Volume envelope. With the default mouse settings, Shift-click the envelope to add points and drag a segment up or down. You can also drag an item's volume handle, the bar along the top edge of the item, to change a whole clip.
- Compression. A compressor reduces the gap between the loudest and quietest parts. As a starting point, try a ratio between 2:1 and 4:1 and set the threshold so the gain reduction meter shows about 3 to 6 dB on the loudest words. Then listen for side effects: breaths getting louder, a squashed or flat sound, or a pumping effect. If any of these appear, back off. Compression often works better after the biggest differences have been smoothed by hand.
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:
- Lower the instrumental a little instead. Raising the vocal uses up headroom. If the master already reaches its maximum, lower the instrumental, or both, rather than pushing into distortion.
- Make a small gap in the instrumental. If your instrumental is a single, already-mixed stereo file, a broad, gentle EQ dip in the midrange, where the voice lives, can open some room. As a starting point, try a wide dip of 2 to 3 dB somewhere in the 1 kHz to 4 kHz region, and switch the EQ on and off to compare. Larger cuts can make the instrumental sound hollow.
- Tidy the vocal itself. Low rumble from the room or the microphone stand takes up space without helping the vocal, and a low-cut filter on the vocal can remove it. As a starting point, set the cutoff around 80 to 100 Hz, and lower it if the voice starts to sound thin. If the voice sounds boxy or muddy, it can stay hidden even when it is loud, so look at its tone as well as its level.
- Pull back the reverb and echo. Less of both brings the voice forward without touching the fader.
- Keep harmonies and doubles under the lead. As a starting point, set them a few dB below the lead, for example 3 dB lower. If the extra vocal parts are close to the lead's level, the lead loses its place at the front.
- Consider the recording. If the take is very quiet, far from the microphone or uneven, a mix can only do so much. A closer, steadier take can be the more effective fix than more processing.
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
- I decided whether the problem is level, space, dynamics, effects or the speakers.
- I set one comfortable playback volume and kept it.
- I fixed the instrumental first and moved only the vocal.
- The words are clear in both the sparse and the busy section.
- The vocal is among the last things to disappear at low volume.
- I compared with a reference that was lowered to match my mix.
- I checked earbuds, a phone speaker and at least one other source.
- I saved a copy of the version before trying another change.
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.
