<pre wrap="">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.

I believe it is adaptive, but no, I haven't used it, because it's
coupled only to the speex codec. We're working on a generic
application and codec-independent jitter buffer algorithm, for use in
asterisk and iaxclient (at least). Some information is available at

The interpolation of lost frames (PLC) is actually done within the
codec, so the jitter buffer just needs to ask for it. Another thing that
this jitter buffer supports (though I've never tested it seriously) is
support for multiple frames per packet.
