Abstract
Sound field control (SFC) aims to accurately reproduce a desired sound field within a specified region, which requires both adaptation to input signal characteristics and precise estimation of acoustic paths between loudspeakers and microphones. To meet these demands, two adaptive algorithms are proposed. The first is a signal-adaptive multichannel filteredx least-mean-square (MCFxLMS) filter designed to handle nonstationary input signals such as speech and music. The second is an acoustic path tracking algorithm that incorporates an input signal decorrelation strategy, enabling robust tracking of multichannel room impulse responses (RIRs) even under highly correlated excitation. Additionally, an alternating modeswitching mechanism is introduced to dynamically activate each algorithm based on predefined criteria. This approach can reduce computational complexity in large-scale multichannel systems while preserving sound field fidelity within the control region.

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
