Perhaps a comparison of the FLAC structure
with that of Vorbis will help.
Within a FLAC stream the audio is split into
blocks which are grouped (interleaved). But
within each block the eight channels are
chained

[OT] Tidy of Wiki Sidebar
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

Define channel order for 7 and 8 channels
Am I supposed to take an "INFORMATIVE" document as standard?
How can one know the output channel order if there is no standard way to map
it on creation?
Being undefined, it's up to the decoders to decide the channel order,
leading to incompatibility among implementations.

More generally, in a stream in the Ogg file.
Codecs are streams, but so are things like
Ogg Skeleton. Information about Metadata
has been collected together in the Xiph Wiki
