How to use iPhone’s mic mode for crystal-clear, noise-free calls

Kurt Knutsson reveals how iPhone’s new Automatic Mic Mode adjusts settings for optimal call quality automatically.
For years, iPhone users have relied on Voice Isolation to block out background sounds during calls, a handy feature for noisy environments or busy homes. However, with the iOS 18 update, things have shifted a bit.
Here’s a question from Debbie in Half Moon Bay that sums up the experience of many users: “Since I updated Apple software to iOS 18.0.1, I can no longer remove background noise while on the phone. This used to be in the Control Center. Have you figured out how to do this?”
That’s from Debbie, a fan of the Voice Isolation feature that used to let her chat on the phone with her dog barking in the background without her callers hearing the noise.
Good news, Debbie. With iOS 18, Apple introduced a smart new feature called Automatic Mic Mode, which adapts to your surroundings to automatically enhance call quality. Voice Isolation is still available, but now it’s part of a more intelligent, hands-free experience.

Automatic Mic Mode builds on the Voice Isolation and Wide Spectrum features that Apple introduced in iOS 15. Now, the mode can intelligently sense your environment and select the best microphone setting for clearer, more natural communication.

HOW TO PROTECT YOUR IPHONE & IPAD FROM MALWARE
This feature isn’t limited to the newest iPhones. If your device supports iOS 18, you can experience the flexibility of Automatic Mic Mode, from iPhone XR to the latest models. Not sure if you’re running the latest iOS? No worries. Here are some quick steps to update your iPhone:

In a Noisy Place? If you’re on a work call in a bustling coffee shop, Automatic Mic Mode will default to Voice Isolation, blocking out background noise so that the other person hears only your voice.
On Speakerphone for a Group Chat? Switch to speakerphone for a group chat, and Automatic Mic Mode may shift to Standard Mode, creating a more open, natural sound that’s perfect for group conversations.
With Automatic Mic Mode, you no longer need to go into settings for most calls; your iPhone now makes those decisions for you. But don’t worry, Debbie, Voice Isolation is still available for manual selection if you prefer.
HOW TO EASILY RECORD PHONE CALLS ON YOUR IPHONE
For those who want to choose Voice Isolation themselves, here’s how to access it in iOS 18.0.1.
1) During a call: Swipe down from the top-right corner of your screen to open the Control Center.
2) Access Mic Mode: Tap on the app controls for your current call near the name of the app (like Phone or FaceTime).
3) Select Voice Isolation: Under Audio & Video, you’ll see options like Automatic, Standard, Voice Isolation and Wide Spectrum. Tap Voice Isolation to reduce background noise. Here’s a breakdown of those options:

Your selection will only affect the app you’re using to make the call. Mic Modes will remain active for that app until you choose a different one.
LET YOUR IPHONE READ ALOUD WHAT YOU CAN’T SEE
With the shift to Automatic Mic Mode, Apple is keeping up with our fast-paced, mobile lives. From noisy environments to quiet settings, your iPhone now ensures crystal-clear calls automatically. And for users like Debbie, who often multitask during calls, it’s a game-changer. Debbie, give it a try! Whether you’re handling household tasks or taking a call on a crowded street, your iPhone will adapt so you can focus on the conversation.
