Frequently Asked Questions
What do I get after processing?
Each job returns downloadable files for the output you selected: stem audio packs, DAW-ready MIDI, and when applicable, PDF score drafts + editable MusicXML.
What audio formats are supported?
MP3, WAV, FLAC, M4A/AAC, OGG, AIFF, and most common formats. If something needs conversion, the app handles it automatically.
How is processing handled?
Jobs run through Music Demixer's secure cloud service to generate your outputs quickly and reliably. You upload once, then download the files for your workflow.
Is there a free plan?
Start with 5 full-quality jobs up to 5 minutes each. No card is required for the trial. Activate Pro from your account when ready for $9.99/mo, and cancel anytime after activation.
Can I use this as an online instrument splitter?
Yes. You can isolate vocals, drums, bass, piano, guitar, and Other from a full song, then download the stems for practice, remixing, or transcription workflows.
Do I need to install software to split a song into stems?
No. Upload audio online, run the separation job, and download the exported stems without local Python, model downloads, or CLI setup.
Can this isolate guitar or piano stems reliably?
Yes, when mix separation is reasonably clear. Dense reverb-heavy masters may leave some bleed and need extra cleanup.
How well does stem separation work on live recordings?
Live recordings are harder because of room bleed and ambience. Studio mixes generally separate more cleanly.
Can I use separated stems with score and MIDI conversion?
Yes. After a stem split finishes, you can start piano sheet music, piano MIDI, Drum MIDI, drum kit pieces, or rough MIDI drafts from the result. Piano and drums use the most specialized transcription paths; guitar, bass, vocal, melody, and Other outputs are still draft note transcriptions for cleanup.
What audio am I allowed to process into stems?
Only process audio you're authorized to use and export. You're responsible for meeting local copyright and licensing requirements.
Can I use the output commercially?
Yes — if you own the rights to the input audio (or have permission or a license), you can use the outputs commercially.

Split Songs into Stems Online for Remixing, Practice, and Transcription
Use this online stem splitter to pull vocals and instruments out of a full song. Upload once, process online, and export separated stems for remixing, sample prep, practice tracks, or transcription workflows.
How online stem splitting works
Upload MP3, WAV, or FLAC, run separation through secure cloud processing, then download individual vocals, drums, bass, piano, guitar, and Other. The sample above lets you hear the split before you process your own track.
What stems you get
Standard output includes vocals, drums, bass, piano, guitar, and Other. Use the stems for remixing, rehearsal tracks, arrangement analysis, quick practice loops, or the next transcription step.
Use it as an instrument splitter online
Need just the drum groove, vocal line, piano part, or guitar phrase? This workflow also works as an online instrument splitter, giving you separated parts to study, resample, edit in a DAW, or hand off to notation and MIDI tools.
Use stems with transcription workflows
Stem separation is useful when you want to route a specific part into notation or MIDI after the split. After the stems are ready, start piano sheet music, piano MIDI, Drum MIDI, drum kit pieces, or rough MIDI drafts from the result page. Piano and drums have the most specialized transcription paths; guitar, bass, vocal, melody, and Other outputs remain draft note transcriptions for cleanup.
No-install export workflow
Everything runs online, so you do not need Python packages, model downloads, or desktop setup. Use MP3 for broad compatibility, WAV for DAW editing, or Opus when you want higher-quality audio in smaller downloads.
