COMMENT:
----------------------------------------------------------------------

Thanks for producing this specification. I have some questions, but nothing at
Discuss level.

I have no idea what an “extreme bitstream” is. Aren’t they all pretty much 0s
and 1s?

More seriously, it would be nice to know what about the bitstream is extreme.
Googling for ‘opus “extreme bitstream”’ turns up one hit for side effects from
a drug being tested, so that wasn’t much help.

Is there an obvious way that the decoder can know whether audio will be
downmixed outside the decoder? Section 10 thinks decoders can know that,
apparently.

In the security considerations, why is it highly unlikely that the read-only
table will be placed next to sensitive data? I’m not balloting Discuss on this
because the assertion is nested in a reported vulnerability with no known
exploit, but I am curious.
