AI Vocal Remover
Remove vocals to keep the instrumental, or isolate vocals to extract an acapella. Lacuna separates your song into two audio files you can preview and download for covers, remixes and edits.
How it works
Split a song into instrumental and acapella in three steps
1Step 1
Upload your song
Drop in any MP3, WAV or FLAC. Your file uploads privately and processes in the cloud — nothing to install.
2Step 2
Remove the vocals
AI splits the track into two clean parts: a vocal-free instrumental, and the isolated vocal on its own.
3Step 3
Play & download
Preview both parts, then download the instrumental, the acapella, or both as MP3 or lossless WAV.
What you get
A vocal remover that leaves the music clean
Separate vocals from the instrumental without the swirl and artefacts older tools leave behind — then keep whichever part you need.
Clean vocal removal
AI separation keeps the instrumental full and natural instead of hollowing it out, so the backing still holds up underneath whatever you put on top.
Vocal isolation and acapella extraction
Keep the isolated vocal as an acapella for edits, mashups and performance study, or download the instrumental to sing over. Both come from the same separation.
Remix right in the browser
Balance the vocal and instrumental, solo either side, and export your own version in the built-in mixer — no DAW required.
Download as MP3 or WAV
Export the instrumental, the acapella, or both. Keep the parts and drop them straight into your set or project.
Who it's for

FAQ
Vocal removal, isolation and acapella questions
An AI vocal remover separates the singing from the instrumental in a finished song and returns both as separate audio files. It also works as a vocal isolator and acapella extractor: keep the instrumental to remove the voice, or keep the vocal to hear it on its own.
Upload any MP3, WAV or FLAC and hit Separate. Lacuna splits the track into a vocal-free instrumental and an isolated vocal — preview and download whichever you need.
Both run the same separation. Use the vocal remover when you want both sides as separate files — the instrumental and the acapella — to mix, sample or edit. If all you need is something to sing over, the Karaoke Maker is set up for that end to end, and carries on into synced lyrics and karaoke video when you want the words on screen.
Upload your song and start the separation. Preview the vocal track, then download it as MP3 or WAV to get the acapella; the instrumental stays available too. Dense mixes, reverb and overlapping instruments can leave some bleed or artifacts in the isolated vocal.
MP3, WAV, FLAC, AAC, M4A and OGG, up to 50 MB and 12 minutes per track. Export the instrumental or acapella as MP3 or lossless WAV.
You get monthly credits free to start, so you can remove vocals at no cost. Heavier use draws more credits, and you can top up any time.
You keep the parts you generate. Just note that removing vocals from a copyrighted song doesn't grant rights to the original recording — make sure you have permission for whatever you release.
