1. Add MP3 files
Use the sample MP3s you supplied, or any local MP3. The browser decodes and analyzes the audio directly.
2. Analysis settings
Phase 7 preserves beat/form, stems, and MIDI-like phrase extraction, then runs a musical autocorrection quality gate before ArrangeAI bridge validation, repair metadata, and import-ready aliases.
3. Optional stem-aware workflow
Add user-supplied stems for the selected MP3 arrangement. Phase 7 keeps the optional stem workflow from Phase 4/5 and carries stem role hints through the quality gate and import bridge so ArrangeAI receives lane-safe metadata.
4. Results
Each completed item can be exported individually. The batch pack stores all analyzed arrangements in one JSON file.
5. Review and correction editor
Phase 7 lets you review guessed tempo, key/scale, downbeat confidence, adaptive form, motifs, cadences, stems, phrase events, autocorrection quality-gate repairs, and import-bridge validation before export.
6. Selected JSON preview
