This hidden setting can improve call quality on iPhone and Mac

A setting accessible in a few clicks from Control Center allows you to enable voice isolation during calls. Delivered discreetly with iOS 15 and macOS Monterey, this feature greatly improves the audio quality of the exchange.

The functionality passed somewhat unnoticed “Voice Isolation” (From where “Voice Isolation” in English) can significantly improve the audio quality of calls in certain applications. This feature, which has been available on iPhone, iPad and Mac since the release of iOS 15 and macOS Monterey, is not given sufficient prominence by Apple and is not automatically activated upon replacement.

In other words, if you didn’t know it, it’s unlikely that you discovered it by accident… and you therefore use it to talk to your family or colleagues on FaceTime, Slack, WhatsApp, Signal or even Instagram, for example . Today we will show you how to use it.

An interesting and practical feature… but badly born

During a call, the function “Voice Isolation” is accessible by going to the Control Center (by swiping from the top right corner of your iPhone/iPad or by clicking on the corresponding menu in your Mac’s menu bar). You should then see the tab “Microphone mode” Top right of the control center: He’s the one we’re interested in. If you click on it, you will see the different modes available, including the function “Voice Isolation” which makes it possible to improve the audio quality of the exchanges.

As TechRadar sums it up, it’s more or less active noise-cancelling technology, but it’s focused on your voice. Of course, your device’s microphones pick up your sound environment so the operating system can filter out parasitic background noise. Your voice will then appear much clearer and vice versa if your interlocutor also activates this function on their iPhone or Mac. It’s reminiscent of the RTX Voice plugin introduced by Nvidia on PC two years ago.

functionality “Voice Isolation” however, has major shortcomings. Not available on some iPhones (iPhone 7 in particular), it doesn’t work with all applications that allow voice or video calls. TikTok, for example, doesn’t support it at all and Zoom only supports it on iOS. Another quirk: this feature is not available for calls “Classic” on the iPhone… which would have been very handy. TechRadar also notes that its activation is not universal. It is therefore necessary to remember to activate it manually with each new application at the beginning of the call, which can quickly become discouraging.

Given the potential of this fledgling feature, we hope Apple can give it more prominence in the future… and why not automatically in conversations about compatible apps.
