Split a song into tracks free, one upload

One upload, seven separate tracks: vocals, drums, bass, guitar, piano, other, plus a clean instrumental. Real stem separation on a GPU, free, no account, no watermark.

From one mixed file to seven stems

A finished song is a single stereo file with everything baked together. StemGrab reverses that: Demucs pulls the mix apart into the individual parts, so you get each instrument as its own MP3 instead of one flattened track.

Vocals — the isolated lead vocal
Drums — the full kit on one track
Bass — the bass line on its own
Guitar & piano — separated where present (experimental)
Other — synths, strings and everything else
Instrumental — the whole mix minus vocals

How to split a song

Open StemGrab and drop your song in (MP3, WAV, FLAC, M4A, OGG — up to 20 min / 2 GB).
Let Demucs separate it on our GPU, usually in under a minute.

What each stem is really for

The seven tracks aren't just a novelty — each one is raw material for a specific job. Here's what people actually reach for once the song is in parts.

Stems for a remix

A remix is a new song built from someone else's parts. Pull out the acapella and drop it over a fresh instrumental you've made; keep the original drums as a groove to build on, or throw them away and program your own; chop the isolated bass and re-pitch it under new chords. Having each element on its own track is the difference between remixing and just DJ-ing over a full mix — you're rearranging the song, not talking over it.

The bass line on its own

Bass is usually the cleanest stem to isolate, because it lives in its own frequency range with nothing else competing down there. That makes it ideal for learning a line note-for-note: solo the bass, slow it down in a player, and loop the tricky bar until your fingers find it. It's also the fastest way to transcribe a part or check exactly what note lands on the downbeat, instead of guessing under a wall of guitars.

A drumless version

There's no single "remove the drums" button — a drumless track is just the split with the drum stem left out. Take the vocals, bass, guitar, piano and other stems, drop them into any DAW or even a multi-track player, and mute the drums. What's left is the song without the kit: perfect for drummers who want to play along to the real recording, or for lifting a melodic section clear of the beat.

Singers building a backing track head to the instrumental maker, and players to practise any instrument with stems. For the mechanics behind it, see how AI stem separation works.

Why six stems and not four

Most separation tools hand you four parts: vocals, drums, bass and one bucket called "other" that holds every remaining instrument in a single file. This runs a six-stem model, so guitar and piano are pulled out of that bucket as well — you get vocals, drums, bass, guitar, piano and other, plus the ready-made instrumental.

That's genuinely more useful, and it also costs something worth knowing about:

Drums, bass and vocals are the most reliable stems. They're rhythmically or tonally distinct enough that the model rarely gets confused, and they're the three you'll trust straight away.
Guitar and piano are the hardest. A clean electric guitar and an electric piano can look remarkably similar to a model, so a rhodes chord sometimes shows up in the guitar file and a palm-muted riff in the piano file. Solo them and you'll hear where the line was drawn.
"Other" is defined by exclusion. Strings, horns, synth pads, organ, accordion, a mandolin — none of them have their own stem, so they all land in "other". A synth lead that sounds piano-ish to you is not a piano to the model, and vice versa.

If a song only really has drums, bass, a guitar and a voice, the guitar stem will be excellent and the piano stem will be near-silence. That's not a failure — it's the model correctly finding nothing.

What bleed sounds like, and how to work with it

Every separated stem carries a little of its neighbours. That's called bleed, and no separation model is free of it. Knowing what it sounds like turns it from a disappointment into something you can plan around:

In the vocal stem: a faint shadow of the snare and cymbals, because both share the frequency range where consonants live.
In the drum stem: traces of bass on the kick hits, and a hint of guitar strum where it lines up rhythmically.
In the bass stem: the low end of the kick drum — the two overlap so far down that separating them is genuinely ambiguous.

Three habits that make bleed a non-issue in practice:

Layer instead of replace. Stems shine when you add something to a song or take one thing away — mute the vocal, double the drums, sample four bars of the piano. Rebuilding an entire mix from six stems is where bleed accumulates and starts to show.
Use the stem you need, not all of them. If you only want the drums, load only that file; every extra stem you stack also stacks its bleed.
Trim to the section you'll actually use. Bleed is worst at the densest moments, so a verse-only loop is often noticeably cleaner than the same stem across the whole track.

You get MP3s at 192 kbps, which is right for rehearsing, sampling, remix sketches and stem-based practice. If your project is going to be mixed and mastered commercially, treat these as a working reference rather than a master source — a lossy stem that's re-encoded again in your export compounds the losses.

Common questions

How many tracks do I get?

Seven per song: vocals, drums, bass, guitar, piano, other, and a mixed instrumental (everything except the vocals), all as 192 kbps MP3 plus a zip of the lot.

How long can the song be?

Up to 20 minutes and 2 GB per upload, in MP3, WAV, FLAC, M4A, AAC or OGG. There's no daily cap.

How good is each track?

Vocals, drums and bass come out remarkably clean on most modern mixes. Guitar and piano are newer, experimental stems and can be rougher in dense arrangements; lo-fi and live recordings are harder for any tool.

Can I get a version with no drums?

Yes, indirectly. There's no one-click "remove drums" — instead you take the split, keep every stem except the drums, and mute the drum track in a DAW or multi-track player. What's left is the full song minus the kit.

Which stem is cleanest?

Bass, usually. It sits in its own frequency range with little competing with it, so it isolates well — handy for learning a line note-for-note or transcribing it. Vocals and drums are close behind on most modern mixes.

Does it work on podcasts?

It's built for music. A podcast or voice memo has no instruments to separate, so you'd just get a near-silent instrumental; the site tells you when that happens.
