Functional stems, aligned
Vocals, drums, bass, and remaining instruments arrive time-aligned to a shared grid, so any subset you combine stays phase-coherent with the rest.
AI Stem Splitter Workbench
the mix, taken apart
Separation you can actually work with
Upload one stereo file and take the mix apart: vocals, drums, bass, and the rest as independent stems you can solo, mute, and rebuild.
The splitter targets the mix's functional layers rather than frequency bands, which is why a bass stem contains the bassline instead of "everything below 200Hz." Each stem exports at full length, aligned to the same timeline, so muting one against the others reconstructs the mix minus that part.
What survives separation depends on the source. Distinct, well-placed parts come out clean; heavily mastered walls of sound and shared reverb leave residue between stems. High-quality input, ideally lossless, gives the model the detail it needs to draw sharp boundaries.
A finished mix is a committed decision — every part glued into two channels. Stem splitting un-commits it. From one upload you get the song as separated layers: the vocal, the drums, the bass, the remaining instruments, each standing alone and each recombinable with the others.
The test of a stem isn't how it sounds solo; it's how it behaves in the combination you'll actually use. Drums destined for a remix need clean transients; an instrumental bed needs the vocal gone without a crater. Audition stems in context before you build on them.
Why splitters live in real workflows
Solo and recombine before download
Audition any stem alone or in combination in the browser. Verify the part you need is clean before a single file lands on your disk.
One upload, every part
No re-running per stem: a single pass yields the full set, and you download whichever layers the project calls for.
From mix to working parts
The mechanical steps are trivial. The judgment — source choice and combination testing — is where results are won.
- 1
Start from the best master
Feed the highest-fidelity copy available. Every re-encode blurs the spectral detail the splitter uses to tell parts apart.
- 2
Split once, audition everything
Run the separation and work through the stems: each alone, then in the combinations your project needs — beat plus vocal, everything minus drums.
- 3
Export what the project needs
Take only the stems you'll use into your DAW or editor, and keep the original mix alongside as the phase and balance reference.
What people do with the parts
Remixing and flipping
Lift the vocal onto new production, or keep the drums and replace the harmony. Stems turn a finished song back into raw material.
Practice and transcription
Solo the bassline to learn it, mute the guitar to play the part yourself, or isolate drums to study the groove without the mix in the way.
Custom performance tracks
Build backing tracks with exactly the parts you need on stage — full band minus the instrument you're playing live.
Judging stems like they'll be judged later
Test in the target combination
A slightly imperfect drum stem may be invisible under a new vocal and unforgivable exposed. The context you'll publish is the context to audition.
Listen for phase and smear
Compare recombined stems against the original mix. Hollow low-mids or swirly cymbals mean separation artifacts that will compound when you process further.
Mind the mastering
Heavily limited masters fuse parts together before the splitter ever sees them. When you have a choice, split the least-compressed version of the song.
Stem splitting in practice
Which stems do I get?
The standard set covers the mix's functional layers — isolated vocals, drums, bass, and the remaining instrumental content — which handles the overwhelming majority of remix, practice, and editing work.
How is this different from the vocal remover?
The vocal remover is the two-way split: voice versus everything else. The stem splitter continues the division so the instrumental side becomes independent drums, bass, and instruments you can manipulate separately.
Will the stems sum back to the original?
Combining all stems reconstructs the mix essentially as you uploaded it — that alignment is what makes subset combinations usable. Tiny differences from the separation process exist but sit well below musical relevance.
Can I use split stems in released music?
From your own recordings and generations, yes. From someone else's song, stems inherit the original's copyright — sampling law applies exactly as it would to the record itself, so clear it before you ship it.
