Poor Audio Quality

[Ney]

The audio quality while broadcasting via iOS SDK appears to be robotic/shrill at times and also suffers interim breakages, even though the user is on a fast internet network. How can we improve the sound quality and give the same audio quality as user gets on FaceTime calls?

If Opus audio codec is used, try adding Opus formats: add opus_formats to WCS_HOME/conf/flashphoner.properties. E.g.,

opus_formats=maxplaybackrate=16000,sprop-maxcapturerate=16000,maxaveragebitrate=20000,stereo=1,useinbandfec=1,usedtx=0

If G.711 audio codec was used - for better quality use Opus.

In case audio is distorted, please
- send flashphoner.log and network traffic dump (tcpdump) to logs@flashphoner.com
- compare audio quality to web client in Chrome
