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 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.

Stem Separation Online for Remix, Practice, and Transcription Prep
Split a song into stems and export each part for editing. Use this workflow to get practical, DAW-ready stems for remixing and production.
What stems you get
Standard output includes vocals, drums, bass, piano, guitar, and Other Lead. Use the stems for remixing, rehearsal tracks, and arrangement analysis.
Why stems improve transcription accuracy
Transcribing isolated sources often yields cleaner notation/MIDI than full-mix input. For notation workflows use MP3 to sheet music. For production, use MP3 to MIDI converter.
Export format guidance
Use WAV when you plan heavy editing or plugin work. Use FLAC for smaller lossless files when storage or transfer speed matters.
