Song splitter free, one upload

Last updated: October 2026

Only on Spotify or YouTube? You need the audio file itself, record it with our voice recorder or extract it from a video file.

Real stem separation on a GPU, free, no account, no watermark. Split the whole song into stems, not just the vocal and the backing: the same upload gives you all seven parts at once.

The free tier runs the same model on your first upload of the day as on your tenth, so split song into tracks free access is the real thing, not a limited trial.

Split song into stems here: one upload returns all seven files, vocals, drums, bass, guitar, piano, other and the instrumental. This full song splitter is free for tracks up to 15 minutes.

Your upload is deleted the moment the split is finished. Want WAV, play-along mixes or longer tracks? The full tool is on the home page.

What we measure on every split

This exact tool has split 112 songs in the period we tracked, but the bigger number comes from the stems themselves: across every track split on the site, we've logged 6,861 individual output stems. Average length: 3.8 minutes. The longest single stem we've produced runs 53.0 minutes; the most common lengths cluster between 2 and 4 minutes (3,257 of them) and 4 to 9 minutes (1,862), with a smaller batch under 2 minutes (546): short intros, outros and loop-length clips mixed in with full songs. 93% of stems land comfortably inside our limits; 25 came out over them, which our systems flag rather than silently truncate. The split itself isn't always instant: the backend endpoint that does the actual separation has logged runs as slow as 125 seconds, 26 times in 40 days, almost always on the longer, denser uploads rather than a typical three-minute song. If a split feels like it's taking a while, that's what's happening in the background, not a stalled page.

From one mixed file to seven stems

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

Free stem separation, done properly: no watermark, no account, and 10 tracks a day. Search song splitter online, ask for a free ai stem splitter, or think of the underlying method as stem separation ai: all three land on the same upload box, and the six-stem output is identical whichever page brought you here.

• 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

1. Open StemGrab and drop your song in (MP3, WAV, FLAC, M4A, OGG: up to 15 min / 2 GB).
2. Let it separate on our GPU, usually in under a minute.
3. Preview each of the seven stems right in the browser.
4. Download the ones you need as MP3, or grab the whole set as a single zip.

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 tool dedicated to just the bass would only ever hand you that one stem; this upload gives you the other six alongside it for free.

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. Under the hood it's the same separation model doing the work on every stem, not a separate tool per instrument.

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. Want the notes instead of the audio? MP3 to MIDI turns each stem into its own MIDI track: everything except drums, which have no pitch to convert.

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:

1. 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.
2. 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.
3. 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.

One upload, every stem

The stem splitter AI behind this page runs the same separation on every file, whatever format you upload, and returns all seven parts together rather than one instrument at a time. As an AI audio splitter it doesn't need genre tags or markers telling it where one instrument starts; the model works that out on its own, and as an AI track separator it handles every instrument it was trained on in the same pass. It's a free stem splitter with no watermark and no credit card, ten uploads a day: as an AI stem splitter free of subscriptions, or a music splitter free of hidden limits, it holds nothing back for a paid plan. The stems splitter free tier and the paid one use the same stem AI. To separate tracks in a song, there's no manual cut-and-paste in an editor: track separation happens in one pass, and the split runs on our GPU rather than in your browser. As a music splitter online free of installs, it lets you split tracks on any device, and you can separate songs one after another, up to 10 a day.

How do I separate a song into stems for free?

Upload the song and download vocals, drums, bass, guitar, piano, other and the instrumental as separate files. It is free with no account and no watermark, for tracks up to 15 minutes and 10 tracks a day.

Can I split a song into stems online without installing anything?

Yes. The separation runs in your browser session on our own GPU, so there is nothing to install. A typical three-minute song splits in seconds, and longer, denser ones can take a couple of minutes.

Can I split a song from YouTube or Spotify into tracks?

Not from a link: you need the audio file. Record the track with the voice recorder or extract the audio from a video file, then run that file through the splitter.

How do I separate a song into stems for free online?

Upload the song to the box above and wait a few seconds. You download vocals, drums, bass, guitar, piano and other as separate files, plus a mixed instrumental; guitar and piano are still experimental. It is free online with no account and no watermark, for tracks up to 15 minutes and 2 GB, 10 tracks a day.
