Audio-to-MIDI Transcription

Convert audio files to MIDI and MusicXML with full music analysis (tempo, key, chords, dynamics, instruments).

Tool

Script: scripts/transcribe.py -- wraps Basic Pitch, Demucs, librosa, and music21. Auto-installs dependencies.

Workflow

1. Identify the input audio file (MP3, WAV, FLAC, OGG, M4A)
2. Determine options:
   • Stems? Add --stems to separate vocals/drums/bass/other with Demucs first
   • Output dir? Use -o path or default to input file's directory
   • Skip analysis? Add --no-analysis if only MIDI/MusicXML needed
   • Skip MusicXML? Add --no-musicxml if only MIDI needed
3. Run the transcription script
4. Report output files and analysis summary to user
