Abstract
Preserving historic recording on gramophone records is an important task because the traditional record play back system damages/wears out records eventually. We present an optical flow based method to reproduce the sound signal from gramophone records using 3 D robust scene reconstruction of the surface orientation of the walls of the grooves. The imaging setup was modified to overcome a shallow depth of field by using a thin glass plate to obtain additional in-focus parts of the image at a second focal length. The sound signal was recovered from the surface orientation and processed further using the industry standard RIAA filter. The overall algorithm has been tested and found to be working correctly using both undamaged and damaged SP records. The algorithm is a "proof of concept" in that it shows sound can be recovered from time-varying 3 D orientation of groove walls.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
