MP3 → Arrangement JSON

Drop MP3 files here, run local browser analysis, and export JSON sketches that can be imported into ArrangeAI Beat Architect as composition/arrangement projects.

Local only No upload, no server, no external libraries.

1. Add MP3 files

Use the sample MP3s you supplied, or any local MP3. The browser decodes and analyzes the audio directly.

Drop MP3 files here or click Choose MP3s above.

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.

Select an analyzed arrangement, then add optional stems.

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.

Analyze an MP3, then choose Preview/Edit on its row to enable Phase 7 review, correction, stem-aware controls, phrase extraction summaries, quality-gate repair summaries, and import-bridge validation.

6. Selected JSON preview

Preview is truncated for speed. Use Export selected JSON for the full file.
