| # Scribe — BASE Station score engine | |
| Audio → lead sheet (ABC with chord symbols), MIDI, and timed key / chord / section annotations. | |
| Built only from permissively licensed components so output is commercially usable: | |
| | Stage | Component | Licence | | |
| |---|---|---| | |
| | Notes → MIDI | Spotify Basic Pitch | Apache-2.0 | | |
| | Beats / downbeats / tempo / meter | CPJKU beat_this (`final0`) | MIT | | |
| | Chords (170-class vocabulary) | BTC-ISMIR19 large-voca | MIT | | |
| | Key, song sections | librosa + in-house code | ISC | | |
| | ABC lead sheet | in-house writer | — | | |
| Endpoints: | |
| - `POST /transcribe` — multipart `file` or form `audio_url` (https), optional `melody_only`, `title` | |
| - `GET /health` — per-component load state | |
| Section labels (A, B, C…) mark repeated material; they are not verse/chorus names. | |
| Melody is a skyline of the transcribed notes — most accurate on a vocal or lead stem. |
