...Either "OggPCM" or "OggPCM Draft2" needs to be deleted. It really doesn't matter which, but I would suggest that "OggPCM" takes the big sleep. Just give time for me (or Sempo) to copy over recent changes. Regards, Martin -- Martin J Leese E-mail: martin.leese@stanfordalumni.org Web: http://members.tripod.com/martin_leese/

...s 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 ?

...s. 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/

...-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/

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