getusermedia - Disabling Auto Gain Conctrol with WebRTC App

Question

is there a way to disable the WebRTC "auto gain control feature" by default, by applying some javascript code to the app files?

i am using simplewebrtc.

You can turn off audio processing using constraints (use https fiddle for Chrome):

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

navigator.mediaDevices.getUserMedia(constraints)
  .then(stream => audio.srcObject = stream)
  .catch(e => log(e));

var log = msg => div.innerHTML += msg + "<br>";

<audio id="audio" controls autoplay></audio><br>
<div id="div"></div>
