Abstract
Content-based analysis of music can help manage the increasing amounts of music information available digitally and is becoming an important part of multimedia research. The use of drums and percussive sounds is pervasive to popular and world music. In this paper we describe an automatic system for detecting and transcribing low and medium-high frequency drum events from audio signals. Two different subband front-ends are utilized. The first is based on bandpass filters and the second is based on wavelet analysis. Experimental results utilizing music, drum loops and Indian tabla thekas as signals are provided. The proposed system can be used as a preprocessing step for rhythm-based music classification and retrieval. In addition it can be used for pedagogical purposes

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
