Ambisonic Channel 137
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).
Ambisonic Channel Number (ACN) = 137
(l,m) = (11,5)
FuMa letter code: none
Conversion factor from FuMa to N3D: not applicable.
Conversion factor from SN3D to N3D:
Associated spherical harmonic
In N3D normalisation
