what are you calling slow ARM core? I experimented voip with alaw and
µlaw on the ti omap 5912 board running at 192MHz and it basically
sucks 80% of the cpu. As for speex i couldn't make it run correctly. I
used gstreamer, so if you tell me you get good results on this kind of
board with these codecs, maybe i have a major overhead in gstreamer
which is something to investigate.
I would appreciate if you could give me some insight.
