Enable HD Audio Dynamically

In this topic they discuss enabling HD Audio by settings values in config.js

Higher audio quality

Hello, we are running online dance events during the corona lockdown, and have used Zoom for that. However, it seems that now when there’s more traffic, the shared audio through Zoom is not too good. The audio sounds like 64 kbps or even less. Is it possible to set a fixed audio bitrate with Jitsi? Something equivalent to 128 kbps would be great. We have up to 50 participants there.

We need to set HD Audio based upon a user setting so setting it in a config file won’t work. We need to set it dynamically.

I already tried adding

audioQuality: {
    stereo: true,
    opusMaxAverageBitrate: 510000 // Value to fit the 6000 to 510000 range.
}

to the connection options but it doesn’t seem to trigger the SDP munging in

TraceablePeerConnection.prototype.setRemoteDescription

I already added the HQ Audio constraints when creating the tracks. Is there a way that I can set those audio settings through lib-jitsi-meet? Or somehow trigger the SDP munging in the function _mungeOpus(description)

When you’re using lib-jitsi-meet there are three places config settings get passed: the JitsiConnection constructor, JitsiConnection.initJitsiConference(), and JitsiMeetJS.createLocalTracks().

jitsi-meet takes settings from config.js and, depending on their purpose, passes them (occasionally under a different name!) to one of these three functions.

I think audioQuality needs to be passed to initJitsiConference().

That did it! Thank you!
