Abstract
Immersive communication systems promise a greatly improved user experience through the use of advanced technologies tailored to various human senses, such as sight, hearing, and touch. This paper focuses on a simulation study of three-dimensional (3-D) sound field reproduction (SFR) for immersive communication. At the transmitting end, the incident sound field is captured via a microphone array, active talkers are detected, and a clean version of the signals corresponding to active talkers are found by existing methods. The captured information is transmitted to the receiving end, where a 3-D sound field from virtual sources corresponding to active talkers is synthesized around listeners' heads by the proposed SFR method. In our system, the radiation patterns of the higher order (directive) loudspeakers are optimized by the constrained matching pursuit algorithm. Implementation of the directive loudspeaker patterns is not addressed here, and their deployment is assumed. Simulation results quantify the benefit of higher order loudspeakers for speech sound field synthesis in reverberant rooms.

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
