[Cellar] Re: Late Agenda Items solicitation

[Spencer Dawkins at IETF <[e-mail]>]

Dear Cellar,

We have two topics on the agenda for today's meeting - the first is making
sure that Martijn and Andrew reply to the RFC Editor with final approval
for FLAC, and the second is what to do about the suggestion for adding
support for more than 8 channels and DSD in FLAC. Given that, Michael and I
agreed to

   - cancel today's meeting,
   - remind Martijn and Andrew to review the final-ish version of FLAC and
   reply to the RFC Editor, and
   - encourage discussion on the mailing list about adding functionality to
   FLAC.

Note that our next meeting is scheduled for 2024-12-10. Michael and I have
an action to propose 2025 meeting dates before that meeting, so we can
discuss things there.

Best,

Spencer
