| # Sever | |
| HTDemucs-6s stem separation for BASE Station. Six stems: drums, bass, other, | |
| vocals, guitar, piano. | |
| Asynchronous by necessity — separation takes minutes on CPU. | |
| - `POST /separate` → `{ audio_url, stems? }` → `{ job_id }` | |
| - `GET /status/{job_id}` → `{ status, stems: { name: "/outputs/..." } }` | |
| - `GET /health` | |
| Jobs run one at a time on purpose: concurrent separations each hold a full | |
| model plus a full audio tensor in RAM and reliably OOM. | |
