WebRTC: Option to disable auto gain control / audio processing e.g. for practicing music

[Oliver Bohlen]

Hi,

we're trying do practise music over WebRTC-based video conference (with e.g. Nextcloud Talk or Jitsi Meetr) together so all participants have so send audio input at the same time.
The default behaviour of Chromium/WebRTC-Apps seems to be that only one (the first or the loudest) or whatever can talk and the other participants are muted or ther volume is set lower.
For sure this is helpful in "normal" conferences while only one is talking and the others are listening but its impossible to practise music.

It would be great to have an option for disabling the "noise cancellation". While googling I found some ideas doing this like here but I want to disable this from Browser-Side:
https://stackoverflow.com/questions/37326846/disabling-auto-gain-conctrol-with-webrtc-app

var constraints = {
  audio: {
   echoCancellation: false,
   noiseSuppression: false,
   autoGainControl: false,
  }
};

We're trying to deactivate this with the followind settings in Chromium but it didn't work:
URL: chrome://flags/
search for "webrtc"
WebRTC multi-channel capture audio processing. -> Enabled

Does anyone have an idea to disable it in Chromium?

Thank you

Hi olli!

I have the same problem as a musician. practice with other band-members is difficult. I hope someone here has an answer to that problem.

Cheers,
