November 2008: The format documented here
is intended for future ambisonic files (etc.). Pre-2009 files typically used a channel sequence of WXYZRSTUVKLMNOPQ (the index page can be used as a concordance), and FuMa channel weightings (conversion factors are on the pages for channels 0 to 15). |
Conversion factor from FuMa to N3D: not applicable. . | Conversion factor from SN3D to N3D:
