Hi, thanks for the framework and the help!
Firstly, I wonder what audio codec does Jitsi use? I have done some search and see https://desktop.jitsi.org/GSOC2011/WidebandCodecs , https://desktop.jitsi.org/Projects/LibJitsi , etc. So I am confused which algorithm does Jitsi choose indeed…
Secondly, I wonder whether there is a “standard” or widely used audio codec, for coding the audio of people’s speaking voice, and has a good compression rate (since data are expensive for mobile phone users)?
Thirdly, it seems that there are so many audio codecs in the world, and this is a very mature and old research field. Therefore, if I select different “classical” audio codecs, will it lead to a very different result, for instance, one codec compresses twice smaller than another? Or, all of them just produce similar results, since the “physical limit” has been almost reached?
Thanks very much for any ideas! If I bother you too much, please ignore my third question.
