Frequently Asked Questions

Will it work in my browser?

Music Demixer works best on modern computers with up-to-date browsers. We run a quick compatibility check and choose the safest mode. If you need help, visit Support.

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 does privacy work?

Private by default — most processing runs in your browser. Some tools may run briefly on our service to generate results, and files are not stored.

How does the 3-day free trial work / can I cancel anytime?

New users start a 3-day Pro trial after signing up. You can cancel anytime from your account page.

What does Multi-Track output?

Multi-Track outputs the main parts in a song as separate MIDI tracks (typically drums, bass, harmony, melody). Track count varies with the arrangement. This is MIDI, not perfectly isolated audio stems.

How is this different from single-instrument mode?

Multi-Track captures the full song in one pass for structure and speed. Single-instrument mode focuses on one part for the cleanest result, especially if you isolate that part first.

Audio to Multi-Track MIDI

Convert a full mix into separate MIDI parts plus a full-score MusicXML draft. Ideal for bands and dense arrangements.

What you get

  • Multi-Track MIDI for the main parts in the mix
  • MusicXML for notation software

Choose the right workflow

Multi-Track is best for a full-song draft. For the cleanest single part, use Audio to MIDI after isolating the instrument with stem separation.

Tips for better results

  • Clean mixes with clear instrument separation give the best drafts.
  • For a single buried part, isolate first and transcribe that stem.

People use this for: full mix to MIDI, multi-track MIDI from MP3, and converting a song to multi-track MIDI.
