To make one person’s voice louder in a video, put their voice on its own track and play it at full volume over the clip’s own sound, turned down. Turning up the whole clip raises everyone. Crele’s speaker isolation gives you that track: it keeps only the person you mark, and the original underneath keeps everyone else, quieter.
Why doesn’t turning up the volume make one person louder?
Turning up the volume raises every voice in the clip by the same amount, so lifting one person over the rest takes their voice on a track of its own, which Crele Focus 1.1 makes from the video. Volume boosters and your editor’s Volume slider work on the whole soundtrack, noise included. CapCut’s Enhance voice separates speech from noise, and the other people are speech, so they stay.
The usual forum advice is to cut the clip wherever the person talks and raise only those parts, or ride the volume with keyframes. That works while they talk alone. The moment someone talks at the same time, that voice comes up too.
How do you make one person’s voice louder in a video?
Keep the person’s voice with Crele Focus 1.1, the speaker isolation model in the Crele app, then lay it over the clip at full volume with the clip’s own sound turned down. It runs in the browser on a phone or a computer, with nothing to install, and a free account is enough.
1Add the video to speaker isolation
In the Crele app, open Speaker isolation and drop the video in, or press Choose a file. On a phone that opens your camera roll, and MP4 and MOV both work. A free account runs files up to 15 minutes on Crele Focus 1.1.
2Mark three to ten seconds of the person alone
Under Speaker to keep, mark three to ten seconds where only the person you want louder is talking. Clean beats long: if someone else talks inside your sample, the tool keeps them too. If the person is never alone in the clip, switch to Upload and add a short recording of them from another time.
3Run it
Press the arrow. The run takes about as long as the clip, and you can leave the page while it works: it waits for you under Recents.
4Download the person's voice
The result shows the original and the isolated voice: the person you marked, on their own. Switch between Original and Isolated while it plays, then press Download for the isolated track as one audio file.
5Lay the voice over the clip at full volume
In CapCut or iMovie, add the downloaded file as its own audio track and start it on the clip's first frame. Leave it at full volume. It runs as long as the video, so the person stays in sync with the picture.
6Turn the clip's own sound down, not off
Select the video clip, open its volume, and lower it until the other people sit under the person you raised. Keep it above zero: the clip's own sound is what keeps the room, the laughter and the street in the video.
How do you make one voice louder in CapCut or iMovie?
Give the voice Crele Focus 1.1 kept its own audio track from the clip’s first frame, at full volume, then lower the video clip’s own volume.
- CapCut. Add the downloaded file as audio from your phone’s files and drag it to the start of the clip. Then select the video clip, tap Volume and bring it down.
- iMovie on iPhone. Move the playhead to the start, tap the plus button and add the downloaded file from Files. Tap the video clip, tap the Audio button and drag the volume slider down, without tapping Mute. If the voice clip is green, iMovie treats it as background music and lowers it whenever the video’s own sound plays: tap it, tap Actions, and choose Foreground.
How far should you turn the background down?
Keep the voice from Crele Focus 1.1 at full volume and lower the original until the other people sit under it: you can tell they are talking, but you follow only the person. Check it on the phone’s speaker and on earbuds. How low depends on the scene:
- A toast at a party. Leave the room fairly high, so the laughter and the clinking glasses come through between lines.
- A child’s lines in a school show. Lower the audience until the coughs and whispers stop competing with them.
- An interview on a street. Lower the passers-by until their words blur into the street.
- Someone quiet across the table. The person holding the phone is the loud one. Run the video once for each of you, and set the two voices level over the original.
If you want the other people gone rather than quieter, mute the original instead, as in how to remove people talking in the background of a video.
How do you make a voice louder than the music in a video?
If the music was playing where you filmed, Crele Focus 1.1 keeps the voice without it, and you lay that voice at full volume over the original turned down, so the music plays on underneath. If you added the music yourself in CapCut or iMovie, it is already on its own track: turn that track down instead. iMovie already lowers background music while a clip’s own sound plays, so lower the music clip only if that is not enough.
Can you make the voice clearer as well as louder?
Yes: run the voice Crele Focus 1.1 kept through Crele Remaster 1 before you mix it, and it comes back with the noise and the room gone, like a close microphone. That helps most when the person was far from the phone. A free account takes files up to 5 minutes for it. The two steps are in how to make one voice clear when other people are talking.
When won’t this work?
Crele Focus 1.1 falls short when it cannot tell the person from everyone else, or has too little of them to work with:
- Someone talks over them most of the time. Where Crele Focus 1.1 cannot tell the two apart, the kept voice goes silent, so the person drops back to the original’s level there.
- They are never alone in the clip. Switch to Upload and add a short recording of them from another time.
- A voice that sounds like theirs. Give it the longest clean sample you have, up to ten seconds. Two similar voices are the hardest case.
- They are far from the phone. There is little of their voice to rebuild. Crele Remaster 1 helps, and a voice that is barely there is past what today’s models can recover.
Questions
- Can CapCut make one person's voice louder?
- Not on its own. CapCut's Volume raises the whole clip, and its Enhance voice separates speech from noise, so the other people come up with the person. Keep the person with speaker isolation first, then raise that voice over the clip in CapCut.
- Why not just mute the original sound?
- Muting it takes away the other people and the place along with them: the laughter, the applause, the street. Turned down instead, they stay under the voice, and the video still sounds like where you filmed it.
- Will the voice stay in sync with the video?
- Yes, when it starts on the clip's first frame. The downloaded voice runs as long as the video, so it lines up with the picture from the start.
- Can I make two people louder?
- Yes, one at a time. Run the video once for each person, marking that person each time, then lay each voice on its own track over the original turned down.
- Does it work on an Android phone?
- Yes. The Crele app runs in the browser on Android as well as iPhone, and it takes an MP4 or MOV from any phone or camera, including a video someone sent you. CapCut runs on both.
- Is it free?
- Yes. A free account runs videos up to 15 minutes and includes 300 minutes of speaker isolation a month. To try it before you make one, the Isolate a Speaker tool on this site runs the first 45 seconds of a video in your browser.
