Muting microphone input with SoundSource

SoundSource provides several ways to mute your microphone, so its input isn’t heard by other apps on your Mac.

Mute in two clicks

1. Click the SoundSource icon in the menu bar to display SoundSource.

2. Click the Mute button next to Input, in the System section.

Mute in a single click, with Menu Bar Meters

Two clicks is good, but it’s possible to mute your microphone with a single click, using the optional Menu Bar Meters.

In the Appearance tab of SoundSource’s Settings (Preferences on MacOS 12 or lower), turn on the Default Input Device menu bar meters.

You’ll now see a microphone and meter icon in upper-right of the menu bar, near the clock. Click anywhere on this visual to mute all input from your microphone. The icon’s level meter will now be X’ed out, to indicate the device is fully muted.

Mute from the keyboard

Muting your microphone input is also possible using a rapid 1-2-3 combination of keyboard shortcuts:

1. Press a configured Global Hotkey to display SoundSource.

2. Press Command-Hyphen (-) to select your microphone.

3. Press Shift-Command-↓ (Down arrow) to mute the microphone’s input.

Automation options

On MacOS 12 and up, it’s also possible to use Shortcuts workflows with SoundSource to mute devices, with the Set Device Mute action. See the Shortcuts page of the SoundSource manual for more details.
