Accoring to the Table.8.1 and Table.8.2 of speex manual (Version 1.2 Beta 2), the
data rates supported by speex codec for narrowband are 3.95, 5,95 ,8 ,11 ,15 ,18.2 and 24.6kbps.
But when I run the code(downloaded from www.speex.org), I am getting data rates of
4,6,8,11.2,15,2,18.4 and 24.8 kbps.
That is, for an input of 20ms frame the number of output bits I am getting are 80,120,160,224,304,368 and 496 whereas
the number of bits given in the Table.8.1 are 79, 119, 160, 220, 300, 364 and 492 .
Can anybody help me in finding out the reason behind this mismatch.
