[Speex-dev] Jitter buffer latency

Hi Jean-Marc,

Thanks for your response.  Given a worst case scenario, what is the "worst case" latency (in terms of Speex frames) that the jitter buffer algorithm will incur?  We're trying to determine the worst case hard number.  Sorry for unclear question below; what I was trying to ask is that given a worst case latency (which I'm asking in the first question) inherent in using the jitter buffer feature, is that any way in the code to reduce the latency?  Thanks.

The latency changes. It's set to the minimum value that will ensure
packets arrive in time. Not sure what you mean by "is there a way to
strink the "late" and "early" bin number to keep the latency in
