By Sam Ridder — I build and run StemGrab on my own hardware, on my own. Who I am.Pull clean stems out of any track to remix — isolated vocals, drums, bass, guitar, piano and other, plus the instrumental — free, no account, no watermark. A stems splitter and stems separator in one pass. It's remix stems free of any account, and ai remix stems come from the same model no matter the genre.
Full-quality stems. No account, no per-track fee. Same model and same 192 kbps (or lossless WAV) as the paid tier — 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.
Split your track free →Getting the key and tempo right before you build matters more than most remixers expect, and our own error logs back that up: elsewhere in the tool family, the message "Nothing to change — move the key or the speed" — someone submitting a pitch change with both sliders left untouched — has fired 29 times in 40 days, a reminder that people come in already thinking about the key and tempo shift they want to make, not just the split itself. On the length side: of every stem produced across the site, 77 came in within 10% of our 15-minute ceiling without tipping over it, which matters if you're pulling a long DJ set or a mixtape apart rather than a single track — the stems hold up close to the limit rather than falling over right at the edge. Neither number tells you whether a remix will sound good; both are the kind of detail you only get from running the tool at real volume, not from a spec sheet.
You can't remix a flattened stereo file — you need the parts. StemGrab gives you the acapella to drop over a new beat, the drums to chop, the bass to re-pitch and the rest as separate MP3s, all from one upload, so you're building from real stems instead of EQ-carving the full mix.
Vocals, drums and bass come out remarkably clean on most modern, well-mixed tracks. Guitar and piano are newer, experimental stems and can be rougher, especially in dense mixes; lo-fi, live or heavily reverbed recordings are harder for any tool. Give the tricky ones a listen before you build on them.
MP3 stems are perfect for sketching and most releases; if you need them at a specific tempo or key, time-stretch and pitch-shift in your DAW. New to how the split works? How AI stem separation works explains it, and split a song into tracks covers the full seven-stem output.
Remixing privately or for practice is always fine. If you plan to publish or distribute a remix, the underlying recording and composition are still owned by someone — clear it first. We wrote a plain-English rundown: stems & the law.
Seven stems is more raw material than most remixes need, and the first decision is what to throw away. A remix that keeps everything is just the original with a different drum pattern. The usual approach is to keep the vocal as the recognisable element, keep one melodic stem that carries the hook, and rebuild the rhythm section yourself: your own drums, your own bass, your own tempo. That's why the drums and bass stems are often the ones you delete first, not the ones you build on. Rebuilding the rhythm section from scratch? MP3 to MIDI turns the bass and the hook into editable notes you can drag straight into a piano roll instead of re-programming them by ear.
Before you place a single clip, write down the key and the tempo that StemGrab shows next to the stems. Those two numbers decide the whole arrangement. If you're remixing a 96 BPM soul track into a 124 BPM house record, you're not nudging a tempo slider, you're deciding whether to time-stretch the vocal (fine up to roughly 6–8% before consonants start to smear) or to chop it into phrases and place each one on the grid by hand. The second approach almost always sounds better on a big tempo change, and knowing the original BPM tells you exactly how far apart the two worlds are before you commit an evening to it.
Set your project key to the song's key rather than transposing the vocal to fit a bassline you already wrote. Vocals tolerate transposition far worse than synths do: two semitones is usually invisible, four starts to sound like a different singer. Everything else in the project can move freely, so let the vocal set the key and build around it.
Importing seven files into a DAW to discover that the guitar stem is unusable wastes twenty minutes every time. The mixer on the results page exists to prevent that. Solo each stem in turn and listen to the second chorus, which is the densest part of most records and therefore where separation is at its worst. Whatever survives the second chorus will be clean everywhere else.
Guitar and piano are the experimental stems and the ones to check hardest: on a busy mix they can trade material with each other or with "other". If a stem doesn't hold up alone, it may still be perfectly usable underneath something else, which is a judgement you can only make by hearing it. Once you've decided, download selected pulls just the stems you're actually going to use, so your project folder holds three files instead of eight.
For DJ edits rather than full remixes the workflow is shorter: take the vocal and the instrumental, note the BPM, and you have an acapella to drop over another record and a bed to talk over. The measured tempo is what makes beatmatching a calculation instead of a hunt.
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.
Yes for most work — 192 kbps MP3 is fine for sketching and plenty of releases. Separation quality matters more than the codec here.
StemGrab hands you the stems in the song's original tempo and key; time-stretch or pitch-shift them in your DAW as needed.
The tool is free to use, but the rights to the recording stay with whoever owns them. Practising privately is always fine; for anything you publish — a remix, cover or mashup — get permission first. See stems & the law.
Upload the track here — StemGrab splits it into vocals, drums, bass, guitar, piano and other, free, no account.
Rather than searching for pre-made packs, upload the original song — StemGrab pulls out every stem you'd need for a remix in one pass.
Yes — this one. Drop in any song and download the individual stems instead of hunting for a pre-split pack.
Most songs never get official stems — upload the regular mix here and the AI separates it into the same seven parts a stem pack would give you.
Yes — any song you upload comes back as seven downloadable stems, free, which covers most remix-contest source material too.
You don't need a pre-made pack — upload the song and download its stems directly, free and on demand.
Yes — upload the track and isolate vocals free, along with drums, bass and the rest, no account needed.
From your own upload only — there's no library of pre-made packs here, just the seven stems StemGrab pulls out of whatever song you drop in.
Yes — most songs never get official stems; upload the regular mix and the model separates it into the same seven parts a stem pack would give you.
On most modern mixes, yes — the vocal comes out clean enough to layer over a new backing, though dense or heavily reverbed originals leave more bleed.
Yes — DJs use the same seven stems for live edit material as producers use for a full remix; the upload and download are identical either way.
Mute, solo or layer any of the seven stems in your DAW instead of EQing or filtering the full mix — that's the whole difference stems make.
Filter, EQ or sample the full mix directly — it's harder to isolate one part cleanly that way, which is exactly the problem separated stems solve.
Yes — the model doesn't treat genre specially; heavy bass and synth-driven tracks separate the same way as any other style.
Most producers pull them from an upload like this rather than hunting for an official release.
Yes — any song in, seven stems out, with no pack library to browse.
Yes — upload the official mix and StemGrab pulls the same seven parts a contest pack would include.
It works from your own upload instead of a fixed library, so any song becomes stems on demand.
Under a minute on our GPU for a typical song, then download the parts as MP3 or grab the zip.
Most tracks never got any — upload the regular mix and the split fills that gap.
Yes — the model treats every genre the same, heavy synths and bass included.
You can make your own — upload the official track and pull the same seven parts a pack would give you.
Drop it into the tool above; the split runs on our GPU and hands back seven files.
