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 convert audio to sheet music online for free?
Yes. Your free preview is one job, and you can download a representative segment up to 30 seconds with no card required. A 5-job Pack or Pro unlocks full-length downloads.
Do I need to install anything?
No. Music Demixer is an online web app, and transcription runs on secure cloud processing. Sign in, upload, and download the results.
Which audio formats can I upload?
MP3, WAV, FLAC, M4A, AAC, OGG, Opus, AIFF, and WebM. WAV and FLAC keep more detail, which can help note and timing accuracy. Upload audio you own or are authorized to use.
What files do I get back?
Each Sheet Music job includes a PDF score draft, editable MusicXML, Original Timing MIDI, and Beat-Aligned MIDI. AI-detected notes, timing, tempo, and bar lines may require editing.
How accurate is online audio-to-sheet-music conversion?
Piano gives the most detailed results. Other instruments return editable drafts. Clean solo recordings or separated stems transcribe better than dense, reverberant mixes.
Can I edit the score in MuseScore or Sibelius?
Yes. Download the MusicXML and open it in MuseScore, Sibelius, or Finale to fix notes, rhythms, spacing, and layout before printing.
From Upload to Score Draft Online
Music Demixer is a web app: upload a recording, let secure cloud processing do the transcription, and download the score files. There is no plugin, desktop app, or Python setup to install.
Three steps from recording to score
Upload an MP3, WAV, or FLAC. Choose the instrument you want notated, or Multi-Track for several parts. Download a PDF score draft for reading, MusicXML for editing, and MIDI for your DAW.
Full songs work without separating first
You do not need to isolate the part yourself. Choose Piano, Drums, Bass, Vocals, Guitar, or Other from a full song and Music Demixer separates that part before transcribing it. Solo recordings and clean stems give the most accurate drafts; reverb and dense arrangements add cleanup.
What to expect from the draft
Piano produces the most detailed scores. Guitar, bass, vocal, and Other scores are drafts that usually need note, rhythm, and layout edits. Review the PDF, then open the MusicXML in MuseScore, Finale, or Sibelius to fix anything before printing.
