An AI separation model on cloud GPUs splits vocals, drums, bass, guitar, piano and other in one pass. It scores 14.62 dB on bass and 14.11 dB on drums on a public multi-genre benchmark, so the kick and bass stay solid instead of smearing.
Solo all six stems free for 30 seconds, with no account. A song is charged once by its length, for all six stems, and your first 1 minute of downloads is free when you sign up.
Every stem starts on the same sample and the six add back up to the song. Download 44.1 kHz WAV, 24-bit or 48 kHz WAV, or MP3, one stem at a time or as a ZIP.
Runs in your browser on desktop or phone, with nothing to install and no GPU needed. Upload audio or video up to 2 GB; files are deleted after 24 hours.
Four steps, from the song file to six stems in your DAW.
Upload the song. Drop an audio or video file up to 2 GB. The preview needs no account.
Listen to 30 seconds. The preview comes from the busiest part of the song. Solo the drums, mute the vocals, or switch back to the original.
Pick the format. 44.1 kHz WAV by default, 24-bit or 48 kHz for your session, or MP3 to save space.
Download. Take one stem, or all six in a ZIP named after your song.
Six stems, each the full length of the song. A part the song does not have comes back nearly silent.
Lead and backing vocals together, with the reverb that sits on them.
Use it for: An acapella for a remix or mashup, or a guide vocal to sing along to.
Kick, snare, hi-hats, cymbals, toms, and most hand percussion.
Use it for: A loop to sample, or a click-free groove to practice over.
Bass guitar, upright bass, and synth bass lines.
Use it for: A bass line to learn by ear, or to mute and play yourself.
Electric and acoustic guitars, rhythm and lead.
Use it for: A riff to transcribe, or a backing track without the guitar.
Acoustic piano, electric piano, and most keys.
Use it for: Chords to study, or a part to hand a piano student on its own.
Everything the five named stems leave: synths, pads, strings, horns, and effects.
Use it for: The rest of the arrangement. Put all six back at full level and you hear the original mix.
Clean enough to use on their own. The stems score 14.62 dB on bass and 14.11 dB on drums on a public multi-genre benchmark, where above 8 dB is usually called professional quality.
| Stem | SDR | What you hear |
|---|---|---|
| Bass | 14.62 dB | Full low end and the pluck of the strings; very little kick drum underneath. |
| Drums | 14.11 dB | Tight kick and snare with crisp hi-hats; the singer rarely ghosts through. |
| Vocals | 11.3 dB | A usable acapella; long reverb tails can split between vocals and other. |
| Other | 8.72 dB | The hardest stem, since it holds many instruments; expect some shared sound. |
Guitar and piano have no published score on this benchmark. Listen to them in the free preview, especially when both play the same chords.
The stem splitter gives you all six stems. These tools give you one finished track for one job, and the free ones work on any song or stem.
Lift the lead and backing vocals out as a clean acapella, with the instrumental as a second download and the tempo and key shown.
Try the vocal isolatorTake the drums out to play along, or keep the drums alone to sample. WAV or MP3.
Try the drum removerThe lead singer goes, the harmonies stay, and your lyrics light up line by line.
Try the karaoke makerTurn a stem or an MP3 into notes on a piano roll and download a .mid file for your DAW.
Try the audio to MIDI converterFind the BPM, key and Camelot code of several tracks at once, then export them as a CSV.
Try the key and BPM finderShift a song up to 12 semitones or set its speed from 50% to 150%, separately, then save the full file.
Try the pitch changerDrag the WAVs into new tracks at bar 1. They are already lined up, so there is nothing to nudge.
All six are the full length of the song, from the first sample to the last, so they stay in sync from the downbeat to the fade.
Other holds exactly what the five named stems leave, so nothing falls between the stems when you rebuild the mix.
44.1 kHz stereo WAV by default, or 24-bit and 48 kHz when your project runs at that rate. MP3 is there when size matters more.
The ZIP and each file carry the song’s name and the stem, so six songs’ stems never get mixed up in a sample folder.
AI separation is an estimate, so some recordings leave faint traces in the wrong stem. These are the common cases and what to do about each.
Pick this stem splitter when you want all six stems from one charge and want to hear them before you pay. Pick LALAL.AI for synth, string or wind stems, Moises if you mostly practise along in a phone app, and UVR if you split hundreds of songs offline on your own GPU.

Each card is a need we hear from musicians, producers, and DJs, with how the stem splitter handles it. These are use-case scenarios, not customer reviews.
Bass player
“I want the band without the bass, with the drums still tight, so I can play along.”
Mute the bass in the preview and the other five stems keep playing in sync. The bass stem scores 14.62 dB SDR, the cleanest of the six.
What each stem containsRemixer
“Stems drift out of time when I drop them into Ableton, and I lose an hour lining them up.”
Each stem is the full length of the song and starts on the same sample, and the six add back up to the original mix.
Using stems in a DAWProducer
“Every splitter I try leaves the singer ghosting in the drum loop.”
The drum stem scores 14.11 dB SDR. Solo it in the free 30-second preview and hear the hi-hats for yourself before you pay.
How clean the stems areDJ
“The only copy of the track I have is a music video file.”
Upload the MP4, MOV, WebM, or MKV itself, up to 2 GB. The soundtrack is split and the stems come back as audio.
Supported filesPiano teacher
“The piano is buried under guitars, and most tools lump it into “other” unless I upgrade.”
Every split has guitar and piano as their own stems, on every plan, so the piano part comes out on its own.
The six stemsLaptop producer
“Demucs sounds great, but my laptop has no GPU and takes forever.”
The split runs on cloud GPUs, so there is nothing to install and your laptop stays free for the session. It works in a phone browser too.
Compared with UVR and DemucsYou can preview 30 seconds of all six stems free without signing up, and download your first 1 minute free when you create an account. After that, a song costs its length in minutes, charged once for all six stems, from $0.025 a minute.
No. Upload a song and hear the preview first. You only sign in when you download.
Some, as with any AI stem splitter. Bleed is lowest on bass (14.62 dB SDR) and drums (14.11 dB) and highest in Other, which holds many instruments. Live recordings and long reverb bleed the most. Solo each stem in the free preview to check before you pay.
Yes. Every split includes guitar and piano as their own stems, with no higher plan needed. Synths, strings, and horns go to Other.
On a public multi-genre benchmark, its stems score 14.62 dB SDR on bass and 14.11 dB on drums, well above the 8 dB usually called professional quality. Unlike UVR or Demucs, it needs no GPU, install, or model settings, and you can hear your own song in the free preview before you decide.
Upload the best copy you have. A low-bitrate MP3 has already lost some of the high end that tells cymbals from vocals, so its stems come out rougher. A 320 kbps MP3 is fine for practice; use WAV or FLAC for a remix.
Yes. Every stem is the full length of the song and starts on the same sample, so they line up at bar 1. Play all six at full level and you hear the original mix.
No. Upload the file itself. Music videos work too: MP4, MOV, M4V, WebM, and MKV up to 2 GB, and the stems come back as audio.
Splitting a song for your own practice or study is generally low-risk. Releasing or monetizing a remix built from someone else’s stems needs permission from the rights holders. This is general information, not legal advice.
If Logic’s stems sound clean enough on your track, you may not. Use this one when you are not on a Mac, want the stems on another device, or want to compare results on a hard mix before you commit.
