Hi Jean and Steve, Can you tell me whether the jitter filter / buffer is adaptive type, I saw the description of speex_jitter.h say it is "adaptive", anyone of the group has implemented it and confirm it. Thank you all. Regards, Danny Chan -----Original Message----- From: speex-dev-bounces@xiph.org [mailto:speex-dev-bounces@xiph.org] On Behalf Of Jean-Marc Valin Sent: Tuesday,

There are still some improvements left to do (e.g. making sure packets are dropped/interpolated during silent periods), but it's already working good. As for being Speex-dependent, I'd say yes and no. It calls speex_decode, which is a Speex "virt...
