src/joc_qmf.py loads the QMF tables, while src/joc_decode.py loads the JOC Huffman trees. Python does not read C/C++ headers under native/.

The corresponding native data are stored in native/src/qmf_tables.h and native/src/joc_huffman_tables.h. Changes on either side should update the other and be checked for value-by-value agreement.

Binaural rendering tables

rosella_kernels.npz contains the fixed QMF/hybrid tables:

qmf_analysis_coefficients       float32[64,10]
hybrid_analysis_low_kernel      float32[3,2,13,16,2]
hybrid_synthesis_indices        int16[154,4]
hybrid_synthesis_values         float32[154]
qmf_synthesis_basis             float64[64,4,128]
qmf_synthesis_taps              float64[64,10,4]

The float32 table values are promoted to float64 when loaded.
