Answer 1

You can stop stream created on MediaRecorder:

navigator.mediaDevices.getUserMedia({audio:true,video:false}).then(function(stream)
{
    recorder = new MediaRecorder(stream);
});
recorder.stream.getAudioTracks().forEach(function(track){track.stop();});

I've edited your question to use multi-line code formatting. I noticed that you use recorder outside of where you call new MediaRecorder. Is that correct? – Gibe

It's a little example. You can set a global variable outsid that function and using it for others method. – Matland

This does not actually mute. This stops the stream. This could be a problem is some scenarios, for example when you want to unmute. Check the @darma answer for details – Hunker

This is useful if you need to 100% stop mic usage, in some cases it's what you need – Susurrus

Answer 2

The previous answer is not ideal because the tracks are actually ended and cannot recover after you called track.stop();, so you cannot unmute for example. Better:

Mute

stream.getAudioTracks().forEach(function(track) {
    track.enabled = false;
});

Unmute

stream.getAudioTracks().forEach(function(track) {
    track.enabled = true;
});

Great. Will this work for video tracks as well? Can we turn off/on the camera after the video/screen capturing has started? – Phalangeal
