Set a better audio quality - Opus at 48000, 2 channels, bitrate of 256 kbit/s

Is it possible to set a better audio quality. We do use high quality Headsets with a Bandwith from 50Hz to 18kHz and sometimes we want to broadcast the videoconference in a large hall with several hundred people with a professional sound system.

In Google Chrome Developer Tools I found this code:
m=audio 54266 RTP/SAVPF 111 103 104 126
a=rtpmap:111 opus/48000/2
a=rtpmap:103 ISAC/16000
a=rtpmap:104 ISAC/32000
a=rtpmap:126 telephone-event/8000

It seems that opus at 48000 and stereo should be possible but it sounds like it uses only a bitrate of 16 kbit/s or it uses ISAC/16000 with only 16 or 32 kbit/s.

Is it possible to add a config-entry in config.js to set the default or preferred codec/bitrate/channels/sampling-rate?

Best regards, Johann

Did you have any luck here?

Hi huntson, unfortunately I have not yet received an answer. Best regards, Johann

Any news about this?

Looks like this thread has some interesting details on how to do it (looks like it requires code changes to jicofo). We haven’t tried it yet but definitely will.
