VAD/CNG module for GIPS ILBC - navithak - Oct 8 6:10:24 2007

 Hi,
I have implemented Gips ILBC codec on adsp 2185..However I am unable
to find any information on the vad/dtx module..Is that royalty free
as well?? Where can I obtain it?Any information will be greatly
appreciated
Another question..Does ilbc pass dtmf tone??

regards
Navitha

Hi Navitha,

The Gips ILBC does not support silence suppression and therefore does not
provide for a built-in vad/cng module.
