Why the Notevibes Stem Splitter
State-of-the-art separation, then a full editor to rebuild the mix.
Four clean stems
A neural separation model (Demucs) splits the mix into vocals, drums, bass, and everything else — each as its own track.
Remix-ready tracks
Each stem lands on its own track in the editor, ready to mute, balance, or rebuild into something new.
Edit by chatting
Once split, just say what you want — “mute the drums”, “make a karaoke version”, “normalize the vocals”.
Instant karaoke or acapella
Drop the vocals to keep the instrumental, or keep just the vocals — a karaoke or acapella track in one step.
State-of-the-art model
Powered by Demucs neural separation for clean, studio-grade stems even on dense mixes.
Download any stem
Export the stems you need as MP3 or WAV — no watermark, no quality loss.
What you can do with stems
One song, four tracks — endless options.
Karaoke tracks
Drop the vocal stem and keep the instrumental for a clean karaoke version.

Frequently asked questions
How many stems do I get?
Four: vocals, drums, bass, and “other” (everything else like guitars, keys, synths). You can also extract just the vocals or just the instrumental.
How good is the separation?
It uses Demucs, a state-of-the-art neural separation model — clean enough for remixes, karaoke, and practice tracks.
Can I get more than four stems?
Yes — use the dedicated guitar and piano extractors to pull those parts out onto their own tracks.
What can I do after splitting?
Each stem is a track in the AI editor, so you can balance, mute, add effects, or rebuild the mix just by describing what you want.
What formats can I upload?
MP3, WAV, M4A, FLAC, and OGG. Each stem can be downloaded as MP3 or WAV.
How long does separation take?
Usually under a minute for a typical song — it runs on a server, so longer files and busier mixes take a little more.
Is it free?
Try it in the AI Audio Editor; separation is metered with credits like the other AI features.
