AI makes the acapella

Secure cloud processing separates instruments from the vocal; the exact time depends on the track and queue.

Preview and download

Free 30-second preview; full acapella in WAV, FLAC, or MP3 with credits.

Hear the separation wall

These licensed source recordings were AI-separated by StemSlice and excerpted to 30 seconds. User uploads are private and never published.

Turn one useful phrase into editable material

Choose the passage first, then evaluate timing, artifacts, and transformation risk.

From any genre

Pop, hip-hop, rock, EDM — if there's a lead vocal, the AI can find it.

Mashup fuel

Pair your acapella with the isolated drums and bass from the same job.

No skills needed

One upload, no audio engineering required.

Private and temporary

Each job expires 24 hours after creation and is then removed by automated cleanup; final physical removal timing can vary.

Move from preview to a documented edit

Keep the source, untouched extraction, intended use, and permission status together.

Choose the musical phrase before polishing the acapella

Find the hook, verse, ad-lib, or harmony stack that will actually be used, then judge that passage in the preview. There is little value in over-processing an entire vocal when the production needs four bars. Keeping edits purpose-specific also makes timing, fades, and permission records easier to manage.

Pitch and time changes come after a clean extraction

First align the original vocal and confirm its tempo. Then apply key or tempo changes in the DAW, using formant preservation when appropriate. Large transformations magnify separation artifacts, so compare a small test render with the untouched extracted stem before committing to a full arrangement.

Acapella creation and sample clearance are separate steps

The tool can produce a workable vocal file but cannot grant a license. A recognizable lyric, melody, or performance may require permission even when it is chopped, pitched, or layered. For released music, keep a record of the source, rights holder, license, and approved use.

Document the source before transforming the phrase

Record the song, version, timestamp, intended edit, and permission status before pitching or chopping the vocal. Large time and pitch changes can hide some artifacts while exaggerating others. Keeping the untouched extracted stem beside the transformed version makes both quality review and rights clearance easier.

Render a small transformation test before exporting the full song

Take the intended four or eight bars through the actual pitch, time, EQ, and compression chain. Separation artifacts can become more obvious after formant shifting or heavy limiting, even when the untreated preview sounds acceptable. A short test saves conversion time and shows whether another source section would survive the production better.

Credits that do not expire

1 credit unlocks one full 4-stem download. Previewing, listening, and failed processing jobs do not consume credits.

FAQ

Answers for free limits, formats, privacy, copyright, and download quality.

How do I make an acapella from a song?

Upload the song here. The AI separates the vocal from the instruments and gives you the acapella as a downloadable file.

Is this acapella maker free?

Making and previewing acapellas is free (3 songs a day). Downloading the full-quality version costs 1 credit, from $4.9 for 5.

What can I do with the acapella?

Remixes, mashups, DJ tools, vocal practice, and covers are the common ones. Commercial releases need permission from the rights holder.

Does it work with any song?

It works best on studio recordings with a clear lead vocal. Very lo-fi or live recordings can produce artifacts.

What's the difference between an acapella maker and an acapella extractor?

Two names for the same job: getting the vocal out of a finished song.

How long can the song be?

Up to 6 minutes free, 20 minutes for paid users.

Do you keep my songs?

Files are encrypted, set to expire 24 hours after job creation, and then removed by automated cleanup; final physical removal timing can vary.

Extracted stems remain the property of the original rights holders. Commercial use requires their permission.
