Option to disable AGC

[TheLastProject]

Description

Automatic Gain Control keeps increasing my recording volume constantly, despite it causing the volume to clip. This is rather annoying and it took me ages to find out what was even causing it (apparently it's a Chromium feature)

Steps to reproduce

• Have a voice or video call
• Notice recording volume rising at random points

Log: not sent

Version information

• Platform: web
• OS: Fedora 27
• Version: 0.13.5

#4634 seems to be related, but I only ever do one-on-one chats so haven't experienced it in conference calls.

Do you know if this is possible to do in Chrome/Chromium?

From my 30 seconds of searching it looks like disabling AGC is supported in Firefox but maybe not elsewhere?

As this is still a problem I searched and in Chorme's "chrome://flags/" I found flag for "WebRTC hybrid Agc2/Agc1" and there is also "WebRTC Echo Canceller 3" which might be good option to be able to disable. Can these options be utilized?

EDIT: I'm referring mostly to option to be able to disable this in desktop (Win) version of Riot.

Any status update? I did my first matrix audio conference a few days ago, and everything went to shit because the auto gain constantly changed the mic level.

having the same problem here. In firefox i disabled autogaincontrol, echo and noise cancellation and audio quality is terrific. I would love to turn those features off in riot-desktop as well since it makes it unusable for me when transmitting anything other than speech.

This problem isn't going away. Google isn't interested in fixing this in Chromium/derivatives. Can we please get this implemented?

More details from a Chromium developer: https://bugs.chromium.org/p/chromium/issues/detail?id=435112#c3

This is hurting the experience for Element VoIP in the most popular browsers. And there is a method to solve this already. Can we get this added to a milestone already? It's been years.

yes, this problem causes the other side to hear deafeningly loud static, I would consider this a major bug
