Vorbis dev - Jan 2003 - AW: PlusV algorithm -> CBR

fwiw, there are definitely applications that would use Vorbis but can't
until there is a _strict_ CBR mode.  Meaning, architecturally the datarate
simply cannot exceed X no matter what happens to the quality.  Send silence if
you have to, but limit the datarate.

Dan,

In situations like this, how is bitrate measured? When you say "cannot
exceed
X no matter what", what time-period is this over? Since vorbis is a 
block-based codec (as are many others, including mp3), it's essential to 
specify some time window - even if that's just a single block (but note that
since there's more than one block size, even that can be problematic).

Nobody seems to want to say what they actually MEAN by "CBR".
