Hello, list!
I'm trying to improve the latency of my end to end system, starting
with the local loop of one of the UA. I'm measuring the latency as
described in [0]. With the following parameters, I'm able to go down
to 74ms in average:
--no-tones \
--ec-tail 0 --no-vad --jb-max-size=1 \
--clock-rate 8000 --snd-clock-rate 48000 \
--rec-file rec1.wav --play-file tock8.wav \
--ptime=10 \
--playback-lat=1 --capture-lat=1
Is there a way to know were these 74ms are spent? It is of course not
a lot but I would be very happy to cut it down by 2 or more. (I'm
trying to use the pjsip stack for a mic application).
Any link, pointer or explanations are welcome.
Thanks a lot for your reply,
-AJ
