To remove background voices from a CapCut video, keep the one voice you want with Crele Focus 1.1, clean it up with Crele Remaster 1, then lay it back on the CapCut timeline. CapCut’s Isolate voice takes out music and street noise but keeps every person talking, and it is not free on every account. Both Crele steps run on a free account.
Can CapCut’s Isolate voice remove other people’s voices?
No: CapCut’s Isolate voice separates speech from music and noise and keeps every person talking, while Crele Focus 1.1 keeps only the person you mark and Crele Remaster 1 then cleans that voice up. CapCut’s own guide says its voice isolator lifts your voice out of “background clutter like music or street sounds”, and none of its audio tools asks whose voice to keep. Reduce noise and Enhance voice treat every voice as one to keep, and the vocal remover splits a song’s singing from its music. If you edit in iMovie instead, how to remove people talking in the background of a video covers it.
A voice memo recorded on a phone with a TV on in the room, played whole, through CapCut's Isolate voice and through Crele Remaster 1 alone. A TV across the room is background, which Crele Remaster 1 takes out by itself; someone talking close to the phone needs Crele Focus 1.1 first.

Is CapCut’s Isolate voice free?
Not on every account: CapCut’s own pages disagree, and both Crele steps, Crele Focus 1.1 to keep the voice and Crele Remaster 1 to clean it up, run on a free account. As of November 2026, CapCut’s voice isolator guide calls its online voice isolator “a totally free way for podcasters and vloggers”, and its background voice remover article ties “Voice isolation” to a paid subscription. If Isolate voice shows a Pro badge on your account, or applies and then blocks the export, it is a paid feature on your account. Free or paid, it keeps every voice.
Why is CapCut’s Isolate voice not working?
CapCut’s Isolate voice usually fails in one of three ways, and only the last, other people still talking after it runs, is the job Crele Focus 1.1 and Crele Remaster 1 do instead:
- It is missing or greyed out. Update CapCut, then look for a Pro badge on it.
- It applies, but the export asks for Pro. Remove the effect to export for free.
- It runs, and the other people are still there. That is how it works: it keeps every voice. Keep the one person with Crele Focus 1.1, clean them up with Crele Remaster 1, then finish the edit in CapCut.
How do you remove background voices from a CapCut video for free?
Keep the one voice with Crele Focus 1.1, clean it up with Crele Remaster 1, and lay the result under the clip in CapCut with the clip’s own sound turned down to 0. Run them in that order: Crele Remaster 1 cleans up the recording it is given, and a person talking close by is part of that recording, so Crele Focus 1.1 picks the voice first. Both run in the Crele app, in the browser on a phone or a computer, on a free account.
1Start from the video's original sound
If you haven't cut the video yet, use the clip from your camera roll. If you have already edited it in CapCut, turn off Isolate voice, Reduce noise and any music you added, and export it, so the file carries every voice as it was recorded.
2Add the video to speaker isolation
In the Crele app, open Speaker isolation and drop the video in, or press Choose a file. MP4 and MOV both work, so there is no audio to extract first. A free account runs files up to 15 minutes on Crele Focus 1.1.
3Mark three to ten seconds of the person alone
Under Speaker to keep, mark three to ten seconds where only the person you want is talking. If someone else talks inside that stretch, 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.
4Run it, then download the voice
Press the arrow. The run takes about as long as the video, and it waits under Recents if you leave the page. Switch between Original and Isolated to check that only the person is left, then press Download for their voice as one audio file.
5Clean up the voice with Crele Remaster 1
Open Speech enhancement and drop in the voice you just downloaded. Crele Remaster 1 takes out the noise and room left around it and rebuilds the voice as if it was recorded on a close microphone. Download the result. A free account runs files up to 5 minutes.
6Lay the voice under the clip in CapCut
Select the video clip, tap Volume and turn it down to 0. Add the file from Crele Remaster 1 as audio from your phone's files and drag it to the clip's first frame, then add any music back on its own track. The voice runs as long as the video, so it stays in sync.
How do you do it in CapCut on PC or Mac?
Crele Focus 1.1 and Crele Remaster 1 run the same way in a computer’s browser, and CapCut’s desktop app takes the finished voice back in three moves:
- Right-click the video clip and choose Separate audio, then delete the clip’s audio track, or turn its volume all the way down in the Audio panel.
- Import the voice from Crele Remaster 1 and drag it onto the timeline under the clip, starting at the clip’s first frame.
- Add back any music you want on its own track, and export.
When won’t this work?
The two steps fall short when Crele Focus 1.1 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, that stretch comes back silent rather than carrying the other person’s words.
- 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 brings back what it can, and a voice that is barely there is past what today’s models can recover.
Questions
- Does CapCut's vocal remover remove background voices?
- No. CapCut's vocal remover splits a song's singing from its music. The person you filmed and the people behind them are all voices, so they land on the same side of the split. Keep the one person with Crele Focus 1.1 instead, clean them up with Crele Remaster 1, then bring that voice into CapCut.
- Why run Crele Focus 1.1 before Crele Remaster 1?
- Crele Focus 1.1 decides whose voice stays. Crele Remaster 1 cleans up the recording it is given, and a person talking close to the microphone is part of that recording, so run it on the voice Crele Focus 1.1 kept rather than on the original video.
- Do I have to extract the audio from my video first?
- No. Crele Focus 1.1 takes the MP4 or MOV as it is and hands back the kept voice as one audio file, which goes straight into Crele Remaster 1 and then onto your CapCut timeline.
- Will the voice stay in sync with my video?
- Yes, when it starts on the clip's first frame. Both steps hand back a voice as long as the video, so it lines up with the picture from the start. If you cut the video afterwards, cut the voice at the same points.
- Does it work with CapCut on Android as well as iPhone?
- Yes. The Crele app runs in the browser on Android and iPhone, and on a computer for CapCut's desktop app. It takes an MP4 or MOV from any phone or camera, including a video someone sent you.
- Is it free?
- Yes. A free account runs Crele Focus 1.1 on videos up to 15 minutes, with 300 minutes a month, and Crele Remaster 1 on files up to 5 minutes, with 60 minutes a month. To try speaker isolation before you make one, the Isolate a Speaker tool on this site runs the first 45 seconds of a video in your browser.
