Audio is meant to be listened to — so you will feel the need for more accessible audio controls.
Check out these Mac Menu Bar Audio Apps:
Dial Bar
With just one click you can start making phone calls. No more fumbling around with your phone! An iPhone is required to make phone calls. You must also enable “Calls on Other Devices”.
MuteKey
Mute ans unmute your microphone, in any app. You can also choose between Toggle and Push-to-talk modes.
Bluesnooze
With this menu bar app the Bluetooth connection is switched off when your Mac sleeps, and switched on when your Mac wakes.
YellowDot
The yellow dot is useful in letting you know if an app is using the microphone. But when you’re familiar with all the apps that use the microphone, it can be an annoyance. When this menu bar app is running, the corner dot will always be hidden.
