Abstract

fetched live from OpenAlex

This paper presents a transient detection algorithm suitable for rhythm detection in music signals. In many audio signals, low energy transients are masked by high energy stationary sounds. These masked transients, as well as higher energy and more visible transients, convey important information on the rhythm and time segmentation of the music signal. The proposed segmentation algorithm uses a sinusoidal model combined with adaptive comb filtering in the frequency domain to remove the stationary component of a sound signal. After filtering, the time envelope of the residual signal is analyzed to locate the transient components. Results show that the proposed algorithm can accurately detect most low energy transients.

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.
