Friend on windows - me on windows ---> very good audio quality
Friend on windows - me on n900 ---> very poor audio quality
Both my laptop and my n900 were in the same wifi network, so I discarded any 3G related issue.
Of course I couldn't find any place to configure it on the phone. Not in the skype account settings, nowhere. After lots of googling and forum searching, I couldn't either find any clue to improve sound quality. Then I thought: silly you, there must be just a /etc configuration file.
And there it was:
/etc/skyhost/skypeaudiocodecs.conf
[G729]
payload-type=18
frequency=8000
channels=1
packet-sizes=20,30,40
default-packet-size=40
min-bitrate=8000
max-bitrate=8000
[PCMA]
payload-type=8
frequency=8000
channels=1
packet-sizes=20,30,40
default-packet-size=40
min-bitrate=64000
max-bitrate=64000
[PCMU]
payload-type=0
frequency=8000
channels=1
packet-sizes=20,30,40
default-packet-size=40
min-bitrate=64000
max-bitrate=64000
First I found somewhere that the G729 codec was used for skype-to-phone calls. I don't know if I am right at that point. So since I'm not interested on that at this moment, I left it untouched.
In the other two codecs I have supposed that the channels lines refer to mono or stereo. I changed them to 2.
I have also tweaked bitrates up to 128000 and frequencies up to 32000. I have noticed some improvements, but still the quality is not as good as in a laptop-to-laptop skype call.
For the other parameters, payload-type and packet-size, I haven't changed anything because I'm not sure what's the effect.
Has anyone had any experience on this kind of tweaking? What would be the configuration that brings the best audio quality? Would anyone like to try and share what he / she finds out?
Thanks in advance and cheers to all the maemo community
