8.4kbps data rate in 8kbps nb mode
I know that most of the narrow band submodes don't have an exact multiple of
eight bits in each frame
79 bits for 3.95kbps
119 bits for 5.95kbps ...etc
This means that you have a few unused bits when transporting Speex in the Ogg
format (you can achieve a lower number of unused bits if you change the number
of frames per Ogg packet to suit the mode).
However, in 8kbps mode, the number of
