Stem splitter & separator
The most complete stem separator & splitter online
Pull apart the parts other separators leave trapped in “other”: vocals, instrumental, drums, bass, guitar, piano, woodwinds, and other instruments — plus individual drum lanes. Every detected part comes back playable and downloadable.
What your track can become
Up to 16 separate stems from one upload
- Vocals
- Instrumental
- Drums
- Bass
- Guitar
- Piano
- Woodwinds
- No-woodwinds mix
- Other instruments
- Kick
- Snare
- Hi-hat
- Toms
- Ride
- Crash
- Cymbals
You receive every part detected in your track, so a simple mix may return fewer lanes. Complete also adds MIDI, editable MusicXML, chords, key, and BPM.

Hear the complete mix, then audition up to 16 isolated stems—including vocals, instrumental, drums, bass, guitar, piano, woodwinds, and individual drum parts when detected.
Why Complete is different
More than four broad audio files
Many free and basic splitters stop at vocals, drums, bass, and “other.” Selekt can detect up to 16 individual parts, then turns the result into a production-ready pack: WAV stems, expressive MIDI, editable MusicXML, chords, key, BPM, and drum one-shots.
Use the files in your own DAW, revoice a part in Stem Lab, or keep the groove and swap the kit in Drum Kit. The demo below shows the separation before you spend a credit.
Start with the result you need
Three focused ways into the same complete engine
Each page preloads the same private separation workflow, but explains the deliverables around a specific job. Pick the doorway that matches what you are trying to make.
Now try your track

Your track opens preloaded in the Audio Workshop, where you choose the separation depth and review the exact credit cost before anything runs.

MP3, WAV, FLAC, M4A, OGG — one track at a time, up to 200MBYour stems are only the beginning
After Selekt separates the detected instruments into playable lanes, it can turn those parts into material you can edit, score, search, and screen. Read our guide to how audio stems and instrument separation work.
Depending on the depth you choose, the same upload can also produce:
- Optional denoise before the separation begins. For focused vocal or archival cleanup, compare the specialist paths in Audio Restoration.
- Full-mix and per-stem MIDI, so you can edit or re-voice individual musical parts instead of transcribing each stem by hand.
- MusicXML notation — an editable score you can open in MuseScore, Sibelius, or Dorico to read, edit, or print the part.
- Chord chart — the timed chord progression, detected automatically.
- Key & BPM detection — the musical key, scale, tempo, and timing information needed to build around the result.
- Whole-track copyright screeningagainst 150M+ commercially released recordings with Complete + Copyright Screen, with every section checked rather than only one excerpt.
- Every format — download each stem and file in WAV, MP3, FLAC, M4A, or OGG.
- Find similar (AI) — match any stem to cleared sounds in the Selekt library by how it actually sounds, and combine them in Stem Lab.
What each one gets you — on Selekt & in your own DAW
Stems
On Selekt: pull a clean acapella or instrumental, sample a bassline, send the drums to Drum Kit. In your DAW: drag each isolated part straight into your project.
MIDI & MusicXML
On Selekt: re-voice any part with a different instrument in Stem Lab. In your DAW or notation app: edit the notes, swap the sound, or read and print the score.
Chords, key & BPM
On Selekt: build a new track around the progression and find sounds that fit the key. In your DAW: match tempo, mix harmonically, and write parts that sit in the same key.
Find similar + copyright screen
On Selekt: match your stem to cleared library sounds and combine them; screen your finished track before release. Anywhere: walk away knowing exactly what you have and where it stands.
Pick your depth
Complete
Up to 16 detected stems and the deep drum split, plus expressive MIDI, editable MusicXML notation, chord chart, key, BPM, and drum one-shots — the full production pack for 0.5 credit.
Complete + Copyright Screen
Everything in Complete, plus a whole-track copyright screen against 150M+ recordings and a PDF Screening Report — split, enrich, and screen your song in one run for 1 credit.
Stems Only
A slightly faster, simpler option when you only want the individual audio stems and do not want extra files you may never use. It skips the Complete production folder with MIDI, MusicXML, chords, key, BPM, and drum one-shots. It costs 0.5 credit; Complete includes the additional files for the same price.
How it works
1. Drop in a track
MP3, WAV, FLAC, M4A, or OGG up to 200MB. Your audio is processed on isolated GPU instances, stays private to your account, and the result files are auto-deleted after 48 hours.
2. AI separates & enriches
A multi-stage process isolates the stems, transcribes the parts to MIDI and MusicXML, detects the chords, key, and BPM, and — with Complete + Copyright Screen — screens the whole track for copyright.
3. Download & build
Grab every stem and file in the format you want, drag them into your DAW, or keep building on Selekt — re-voice a stem in Stem Lab or re-skin the drums in Drum Kit.
Frequently asked questions
Is there a free stem splitter online?
Yes — you can try Selekt’s stem splitter with the free trial, right in your browser. There is no plugin to load into a DAW and no software to download or install. Browsing the cleared catalog, where every track already ships with separated stems, is free too.
How do I separate the instruments from a song?
Upload the song and the AI separates the instruments into individual stems — vocals, bass, guitar, piano, woodwinds, drums, and more — each one downloadable on its own. Mute the vocal for an instrumental, take the vocal alone for an acapella, or pull just the part you want.
What do I get back — just stems?
Far more than stems. Beyond up to 16 isolated stems, Selekt transcribes the parts to MIDI, scores them to editable MusicXML notation, detects the chord progression, and reads the key and BPM — and with Complete + Copyright Screen it screens the whole track against 150M+ recordings before you release. It is the same engine that enriches every track in the Selekt catalog.
Can I hear a stem-separation demo before I upload?
Yes. The prepared demo lets you play the complete mix, reveal the separation, and audition each detected stem before uploading your own track. It demonstrates the same browser-based result layout, including vocals, instrumental, drums, bass, guitar, piano, woodwinds, other instruments, and separate drum parts when they are detected.
Do I need a plugin or audio separation software?
No. Selekt is online audio separation — the heavy lifting runs on our GPUs and the finished stems and files stream back to your browser. There is no stem-splitter plugin to install in your DAW and no separation software to set up on your machine.
Can I get an acapella or instrumental from a song?
Yes. The vocals stem is your acapella; the ready-made instrumental is everything but the vocal. Because separation is per-stem, you can also isolate just the drums, just the bass, just the piano, and so on.
Is my audio kept private?
Yes. Uploads are processed on isolated GPU instances, stay private to your account, and the result files are auto-deleted after 48 hours. Selekt does not listen to your audio or add it to the catalog.
