Option to disable auto gain control / audio processing for practicing music

[egabosh]

Is your feature request related to a problem? Please describe.

We're trying do practise music over nextcloud talk together so all participants have so send audio input at the same time.
The default behaviour 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.

Describe the solution you'd like

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,
}
};

Describe alternatives you've considered

We're trying to deactivate this with browser settings e.g. for chromium this way:
URL: chrome://flags/
search for "webrtc"
WebRTC multi-channel capture audio processing. -> Enabled

In zoom it seems to be possible to disable it but I don't want to use it for many reasons ;-)

Would be great if you offer this option.

The biggest problem we currently face is that when you want to change such a setting, you have to reconnect :(

It would be no problem for me to reconnect.
Maybe the option could be global in the Talk settings?

Sorry, didn't mean to close it.

OK, we tried to do the following with Chromium:

URL: chrome://flags/
search for "webrtc"
WebRTC multi-channel capture audio processing. -> Enabled

And start Chromium with the following options
chromium-browser --disable-audio-track-processing --audio-buffer-size=16 --enable-exclusive-audio

Both didn't work for us.

Does anyone of you know a way to force deactivating the auto gain control by the webbrowser?
This would be a useable workaround for us.

Hi!
I have the same problem as a musician. It's hard to practice with other band-members this way. I hope someone comes up with a solution. Thanx!
