Look for Mic Mode
You can access Control Center on the iPhone and iPad by swiping down from the top right-hand corner of the screen and on the Mac by clicking the Control Center icon in the menu bar.
Note that Mic Mode only appears when you’re running an app that supports the feature, such as FaceTime, Zoom, and so on.
Not only do you need to be in an app that supports Mic Mode — FaceTime, Zoom, Facebook Messenger Video to name a few, you also have to be in an active call for the option to appear in Control Center.
Mic Mode has three settings:
Standard
Voice Isolation
Wide Spectrum
Standard is the default setting that Apple uses, a sort of middle ground where the mic picks up your voice but also some of the ambient sound.
Wide Spectrum makes the mic pick up everything, with an emphasis on catching the ambient sound too. This can allow for an immersive experience, but the quality and clarity of the voice can suffer.
The setting you want to pick for the best voice sound is Voice Isolation. This captures your voice and filters out as much of the ambient sound as possible.
Select the one you want… during your call, that’s it. Enjoy sounding better during your calls.
