Abstract

fetched live from OpenAlex

High Dynamic Range (HDR) compositing is well established in the field of image processing, where a sequence of differently-exposed images of the same scene are combined to overcome the limited dynamic range of ordinary cameras. We extend this technique to audio. Rather than acquiring samples separated by time or space, as is done in HDR image processing, we propose to perform simultaneous sampling of the same input signal, using differently-gained versions of the same HDR signal fed into separate analog to digital converters (ADCs). An HDR audio signal is thus sampled by merging a set of low dynamic range (LDR) samplings of the original HDR input signal. We optimize the choice of LDR input gains to achieve as high a dynamic range as possible for a desired sampling accuracy.

Full frame distilled prediction

Teacher imitation

Not 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.
