...d_name_proposal This is a mess, and all I could do was add attributions to the discussion. Will somebody who was involved in the discussion please tidy up this mess. I also moved a failed proposal over to the Talk page. Please check I didn't break anything.

...bytes (16 exabytes). A FLAC metadata block is limited to 2^24 bytes (16 megabytes). Therefore, a VorbisComment can be orders of magnitude bigger than a FLAC metadata block. Visit: https://wiki.xiph.org/Metadata The advice to use a VorbisComment still looks good.

...ng up bits of the Wiki. This one is not clear cut, so I decided to seek advice. Also, I wasn't sure where to post this question, so defaulted to ogg-dev. Should Speex and CMML be removed from the Wiki Sidebar at: https://wiki.xiph.org/MediaWiki:Sidebar ?

...rently to support Ambisonics. So I downloaded the code from the xiph download page for libogg-1.1.3, libvorbis-1.1.2, vorbis-tools-1.1.1 and flac-1.1.4, but wasn't able to find anything. If it exists then I missed it, so could somebody please point me to it. Many thanks, Martin -- Martin J Leese E-mail: martin.leese@stanfordalumni.org Web: http://members.tripod.com/martin_leese/

For more obscure layouts, such as 2.1 and Mid/Side, assume that the person doing the encoding knew what they put in, and so knows what will come out.

...tail on what is a "non-audio" RIFF chunk? Ambisonic ".amb" files are WAVE-EX files with a non-standard GUID in the 'fmt ' chunk. I want to work out is this can now be preserved in FLAC files. (And, I am interested in metadata anyway.) Many thanks, Martin -- Martin J Leese E-mail: martin.leese@stanfordalumni.org Web: http://members.tripod.com/martin_leese/

...rhaps I have misunderstood your problem, but is this not what magic numbers are for?

Supporting RF64 instead of CAF would solve Brian's problem equally well, and would be the natural extension to supporting WAVE.
