Modulo that correction, that's probably something that anyone who has ever done any maths related to HOA decoding, beamforming, rotation, etc. will confirm without any reservation. Another matter: what is the 'official' definition of IEM's Ambix format ? Problem is that I find contradicting info. There's the paper: <http://iem.kug.ac.at/fileadmin/media/iem/projects/2011/ambisonics11_nachbar_zotter_sontacchi_deleflie.pdf> and the source code on Github: <https://github.com/umlaeute/ambix/blob/master/libambix/src/uuid_chunk.c> These mention different UUIDs for the extended (with matrix) format. Also in the paper it is at least suggested (Fig. 1) that the matrix dimensions are 32-bit floating point, while the code uses 32-bit integers (which makes sense). Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities.
