+The handle owns the complete runtime: 64-QMF/77-hybrid analysis and synthesis,
+fifth-order ACN/N3D real spherical-harmonic direction-field evaluation,
+per-object whole-QMF-slot delay histories, six first-order image-source early
+reflections, the shared unitary-FDN late room, the 120-180 Hz LFE low-pass and
+the 961-sample latency compensation.  The caller configures the filterbank
+tables, the compiled HRTF field and the room constants once, then per 512-sample
+block updates every source with ejoc_sofa_binaural_set_source() and calls
+ejoc_sofa_binaural_process().  Process returns the number of trimmed stereo
+samples written; the first 961 processed samples across calls are discarded.
