TITLE
-----
G.729 annex D bitstream format of the lower rate (6.4 kbit/s).



BITSTREAM FORMAT
 
For rate 6.4 kbit/s, 

the bitstreamfile contains for each 10 ms speech 
frame, 66 16-bit words.

The first word is the syncword SYNC_WORD

The second word is the framesize contains the value 64.


The next 64 words contain the following parameters:
