Temporary Sound Mute (for those funny friends)

Sometimes some of my friends blast fullo volume ear rapes in voice chat and I have to mute my sound and wait a random time before trying to unmute it. It would be cool if it was a customizable hotkey that muted sound for a customizable number of seconds (like 5 or 10 seconds) and unmuted it automatically after the time is up. It would really ease the communication with those funny friends that everybody knows.
Thanks for an amazing app though, you're the best!
