Sample Match Verifier

Upload a track and a possible source sample. Waveforms appear immediately on upload. Click Verify match to run the model — it scans beat-aligned windows, scores the best match, and highlights the predicted sampled sections on both the waveform and mel spectrogram. If no confident match is found, the mel spectrogram shows a No Match overlay.

Model checkpoint

Place your checkpoint at models/best.pt (committed via Git LFS) or set the MODEL_CHECKPOINT environment variable to its path. The app falls back to checkpoints/best.pt if models/best.pt is not found.
