Hi Anisse,

I don't have any comments (yet) because I just started reading, but from 
just looking at some tables there's a few things I don't understand. Could 
you please clarify these:

1) How much is "very low delay" and how much is "medium delay"?

2) What do "NWT" and "BT" mean?

3) What's the difference between the "Reference Codecs" column and the 
"Requirements" column?

4) How do you define the rates that do not exist in some codecs? For 
example, I see a reference to 12 and 16 kb/s for Speex, which has no such 
rates, and to 8, 12, 16 kb/s for iLBC, which does not have these rates either.

Thanks,

	Jean-Marc

Further updates are planned, but let's see first some initial comments.
