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.<br><br>Regards,<br>Andy<br><br><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;">----- Original Message ----<br>From: Jean-Marc Valin <jean-marc.valin@usherbrooke.ca><br>To: Andy Ngo

The latency changes. It's set to the minimum value that will ensure<br>packets arrive in time. Not sure what you mean by "is there a way to<br>strink the "late" and "early" bin number to keep the latency in
check?".<br><br> Jean-Marc<br><br>Andy Ngo a écrit :<br>> Hi,<br>> <br>> Our project is using the jitter buffer feature built in Speex.
