Mute Me

Mute Me is a touch bar app to mute/unmute your microphone. When you’re in a meeting using Hangouts, Skype, Slack, or another voice application, it's good practice to stay on mute until someone speaks to you directly - especially if you’re meeting with three or more people.

Often, however, you'll need to browse between multiple tabs, and it can take too long to switch back to the meeting app to unmute your microphone, and here is where Mute Me can really help you.
