Heart-murmur screening entirely in your browser — a 404K-parameter model runs locally via WebAssembly. No audio leaves your machine.
1 · Input
Upload a WAV / MP3 / OGG recording (5–15 s recommended, 4 kHz target; longer clips are trimmed to the first ~8 s). The model was trained on 4 kHz phonocardiograms recorded with a digital stethoscope at the mitral valve — other positions are supported but may be less reliable.

⚠️ Screening signal only — not a medical diagnosis. This model detects murmurs with
sensitivity ≈ 0.78 (s_murmur) on the held-out PhysioNet 2022 test set; it cannot replace a clinician.
