Frequently Asked Questions
What do I get after processing?
Each job returns downloadable files for the output you selected. Depending on the task, that can include an editable Guitar Tab file, with Guitar and Backing track audio added for full-mix Tab jobs; stem audio packs; DAW-ready MIDI; and 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 one Free Preview job, including downloads from a representative segment. Buy a 5-job Pack or subscribe to Pro to process more jobs and download full-length results.
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. Use the actions beside each stem for piano Sheet Music or MIDI, Drum MIDI or kit separation, and editable MIDI drafts from guitar, bass, vocals, and Other. If a shortcut is unavailable, download the stem and upload it to the next task. Notes and timing may need editing.
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.
Work with Six Separated Stems
Standard output includes vocals, drums, bass, piano, guitar, and Other. The Other stem collects remaining sounds, such as violin, flute, brass, and synths, together in one track. Download the parts as MP3, Opus, or 16-bit WAV for remixing, rehearsal, sampling, arrangement study, or transcription.
Preview, rebalance, and export
The Stem Workspace lets you preview individual parts, adjust their levels, export a custom WAV mix, or download the original separated files.
Continue from a stem
Available shortcuts include Sheet Music or MIDI from piano, Drum MIDI or kit separation from drums, and editable MIDI drafts from guitar, bass, vocals, and Other. Use the action beside a stem when it is available. Otherwise, download the stem and upload it to the task you want. Notes and timing may need editing.
What affects separation quality
Dense arrangements, reverb, live-room bleed, and heavy compression can leave artifacts between parts. Clear studio mixes generally separate more cleanly.
