Firefox adjusts the microphone volume level on the computer, but not Chorme

It seems that Firefox is somehow able to automatically control the microphone input volume level on my computer, and in real-time it adjusts the level to either low & high, depending on my how loud I speak on the mic.

The Windows Sound configuration dialog on my computer for the microphone

I used this link to test for this feature: https://webaudiodemos.appspot.com/pitchdetect/index.html

How can I achieve the same on the Chrome? Is there a special Chrome setup for this? Or, is there a Chrome plugin for this, or even a 3rd-party plugin? Also, is it possible to accomplish this using JavaScript after the end-user has granted browser access to the microphone?

That's easy, you remove this section of code:

            "mandatory": {
                "googEchoCancellation": "false",
                "googAutoGainControl": "false",
                "googNoiseSuppression": "false",
                "googHighpassFilter": "false"
            },

(My pitchdetect demo is explicitly cancelling the AutoGainControl and echo cancellation stuff in Chrome.) You can't change it after calling getUserMedia (though you can call getUserMedia again).
