Split a song into instruments online — stems: vocals, bass, drums
Upload a track and get four WAVs: vocals, drums, bass and everything else. The Demucs neural network splits the song into instruments on the server, no DAW or plugins: processing takes about 4× the track length.
Split my track →How it works
- Upload your track — WAV, FLAC or MP3 up to 200 MB in the app.
- Press 'Split into stems' — a card in the PRO modules block. Processing takes about 4× the track length (a 4-minute song takes about 17 minutes); the screen shows the time left, and the finished archive stays in your profile for 24 hours even if you close the tab.
- Download the zip — four WAVs: vocals, drums, bass, other. The archive is kept for 24 hours.
- Price — 1 token, charged only after successful separation. Failures cost nothing.
Two modes to choose from
- All tracks — vocals, drums, bass and other: four WAV files for mixing and remixing.
- Vocals and instrumental — the voice on its own, the backing track on its own. One run gives you both: an a cappella and a karaoke-ready instrumental.
What stems are used for
- Instrumental / acapella — remove vocals for covers and karaoke, or keep only the voice.
- Remixes and mashups — kick and bass separate from the harmony.
- Learning parts — hear the bass line or drums without the rest of the mix.
- Stem mastering — per-track processing: we also offer stem mastering.
Questions and answers
How do I split a track into stems online?
Upload the track in the app and press 'Split into stems' — the Demucs neural network splits it into four tracks: vocals, drums, bass and the remaining instruments. Processing takes about 4× the track length (a 4-minute song takes about 17 minutes); the finished zip with four WAVs stays in your profile for 24 hours.
Which stems is a track split into?
Into four stems: vocals, drums, bass and the remaining instruments. Each one downloads as its own WAV file. Separation is done by the Demucs model — the same one used in professional tools.
Do I need software or a plugin?
No. Separation runs online: you upload the file in your browser and get the finished tracks back. No DAW, plugins or installation needed — you can A/B the result right on the page.
Can I extract clean vocals from a song?
Yes, the vocal track comes as a separate file. Quality depends on the source: on a dense mix with heavily processed vocals you may hear separation artefacts — that is a limit of any algorithm, not of this service in particular.
How much does stem separation cost?
The first basic mastering each day is free (by UTC), no card needed. Stem separation is part of PRO processing: 1 token = 1 track, paid in roubles via YooKassa.
Can I split a song into instruments online?
Yes — that's exactly what stem separation does: the song is split into instrument tracks. Vocals, drums and bass each get their own WAV, while guitars, keys and synths go into the "other instruments" track. A 4-minute song takes about 17 minutes, then you download the instruments as separate files.
Can I remove a voice tag from a beat?
Yes, if the tag is a voice layered over the beat: the "Vocals & instrumental" mode removes the voice tag along with any other vocals, leaving a clean instrumental. Honest limit: if the tag is baked into the instrumental itself (mixed with the melody on one track at creation), the algorithm can only take out the voice part.
How do I split a Suno track into stems?
Download your track from Suno in the best quality and upload it on this page — Demucs splits it into vocals, drums, bass and the rest, like Advanced Split but without a Suno Premier subscription. You can then master the stems separately and clean up generation artifacts.
