We're trying do practice music over WebRTC based Video-Conferencing tools like Nextcloud Talk or Jitsi so all participants have so send audio input at the same time. The default behavior seems to be that only one (the first or the loudest) or whatever can talk and the other participants are muted or the 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". I found some ideas doing this in the web like here: https://stackoverflow.com/questions/37326846/disabling-auto-gain-conctrol-with-webrtc-app

var constraints = { 

audio: {
  echoCancellation: false,
  noiseSuppression: false,
  autoGainControl: false,
}

};

But this solutions seems to be on the Application-side and not Browser-side.

Has anyone an idea how to disable it in Firefox e.g. some settings in about:config?

This doesn't appear to be a configurable setting in about:config, I'd look more into the applications you're using, such as Jitsi to see if they have any support or answers on this question, a setting you can change in the app / website.

Jitsi and Nextcloud Talk doesn't seem to be interested in it - No further answer. Tried their Support: https://github.com/nextcloud/spreed/issues/3252

So I try to find a way over the browser which seems to be possible mentioned in this post:

https://stackoverflow.com/questions/37326846/disabling-auto-gain-conctrol-with-webrtc-app

"Both Chrome and Firefox (64+) appear to default autoGainControl to true. Older versions of Firefox would default autoGainControl to false and noiseSuppression to true, but like all device settings, defaults may vary from browser to browser, device to device or even the situation, so if you care about a setting, constrain it. All three settings can also be controlled individually in Chrome and Firefox."


But I don't find the autoGainControl in about:config so how can i configure this?
