I have been tidying 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 ? Many thanks, Martin -- Martin J Leese E-mail: martin.leese stanfordalumni.org Web:

This is a minor point, but FLAC users can already do this using METADATA_BLOCK_PICTURE (which

Hi, I have posted this three times to the flac-dev, vorbis-dev, and ogg-dev mailing lists. I wanted to see what code there was currently 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.

Not sure if this belongs here or in flac-dev. I am subscribed to both, so flop it over if fits better over there. Looking at the Changelog for FLAC 1.2.1 (17-Sep-2007), it says: "With the new --keep-foreign-metadata in flac, non-audio RIFF and AIFF chunks can be stored in FLAC files and recreated when decoding." Where can I find more detail on what is a

I have been tidying up the VorbisComment page in the XiphWiki. The problem with it was that it was a mixture of proposals and discussion of those proposals. This made it difficult for implementers to see what to implement. The problem section is: http://wiki.xiph.org/index.php/VorbisComment#New_ENCODER_field_name_proposal This is a mess, and all I could do was add attributions to the
