Appears to be free, as well.

It puts an icon in the menubar with a mic input level slider:

  1. Good UI.
  2. Adds icon in the menu bar.
  3. Ability to add keyboard hotkey.
  4. Can select among input devices.
  5. Free.

Same disclaimer as earlier answer: No financial or any other ties to the developer. Just found the app on the app store and love it.
