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, printable PDF + 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 finished files for your workflow.
Is there a free plan?
We offer a 3-day free trial with full access. After the trial, you can keep Pro or cancel anytime from your account page. Card required to start the trial.
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 prep.
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.
Do isolated stems help with score and MIDI conversion quality?
Usually yes. Isolated target parts reduce overlap and often produce cleaner transcription drafts.
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 isolated stems for remixing, sample prep, practice tracks, or transcription cleanup.
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 demo 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, or quick instrument practice loops.
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 cleaner parts to study, resample, edit in a DAW, or hand off to notation and MIDI tools.
Why stems improve transcription accuracy
Transcribing isolated sources often yields cleaner notation or MIDI than feeding in a full mix. For notation workflows use MP3 to sheet music. For production, use MP3 to MIDI converter.
No-install export workflow
Everything runs online, so you do not need Python packages, model downloads, or desktop setup. Use WAV when you plan heavy editing or plugin work. Use FLAC for smaller lossless files when storage or transfer speed matters.
