What you get
Vocals + Instrumental gives you two WAV files: the isolated vocal, and the whole song with the vocal removed. Use it for karaoke, remixes, or a clean acapella.
All stems gives you five: vocals, drums, bass and other, plus a backing track with the drums removed for practising along to. Every file comes back as a 44.1 kHz, 16-bit stereo WAV.
How it works
- Pick a mode and drop in a song.
- Wait about as long as the song is. The page counts down while the model works.
- Download the stems. They are deleted from our server an hour later.
From drums to MIDI
In All stems mode the drums row has a Transcribe these drums button. It sends the stem to the CedarGrooveNET drum transcriber, which turns the groove into an editable pattern you can export as MIDI. If drums are all you came for, the isolate drums page is the same tool with that mode preset.
Frequently asked questions
Is it free?
Yes. There is no account, no signup, no watermark and no limit on how many songs you split beyond a short per-hour cap that keeps the server responsive for everyone.
Which formats can I upload, and what do I get back?
Upload WAV, FLAC, AIFF or MP3, up to six minutes. You get 44.1 kHz, 16-bit stereo WAV files back: vocals and instrumental in Vocals mode, or vocals, drums, bass, other and a drumless backing track in All stems mode.
How long does it take?
About as long as the song is. A three-minute track takes roughly three and a half minutes; the page shows a countdown while it runs, and a queue position if someone is ahead of you.
Do you keep my file?
Your file and the separated stems are stored on our server while the job runs and for one hour afterwards, then deleted automatically. Transcription on its own still keeps your audio in memory and never writes it to disk.
Which model does it use?
Hybrid Transformer Demucs, the strongest freely available source-separation model. Both modes run the same model; Vocals mode simply gives you the vocal stem and everything else mixed back together.
Can I get MIDI from the drums?
Yes. In All stems mode the drums row has a Transcribe these drums button that sends the stem to the CedarGrooveNET drum transcriber and opens it in the grid, ready to edit and export as a Standard MIDI File.
Why WAV and not MP3?
Stems are usually processed further, and a lossy encode at that point costs quality you cannot get back. WAV is larger to download but is the format a DAW wants.
What if my song is longer than six minutes?
It is refused: WAV, AIFF and FLAC files that are too long are refused in your browser before anything is uploaded, and an over-length MP3 is refused by the server. Trim the song first, or split it in two.
