Apple actually added two audio modes for apps to take advantage of, Voice Isolation and Wide Spectrum. Voice Isolation is definitely the more useful of the two. Wide Spectrum is not so useful unless your group call has an actual group in one room. That’s because it focuses the audio onto the background noise, minimizing your own voice.

The setting you want for most situations is Voice Isolation. It tunes out background noise when turned on, so you come through clearly and cleanly. That could be removing traffic noise or just the general background hum of a coffeehouse.

To enable Voice Isolation:

• Open an app that supports Mic Modes, such as FaceTime
• Click the FaceTime icon in the menu bar, then click Mic Mode
• Choose Voice Isolation
