iOS
Improve the sound quality of phone calls
One of the best new features in iOS 16.4, which was released at the end of March, lets you improve the audio quality of phone calls you make on your iPhone. It’s called Voice Isolation and uses machine learning to remove background noise and block microphone interference so your calls sound clearer than ever.
Previously, Voice Isolation was available for VoIP calls in apps such as FaceTime and Skype, but it now works for calls you make over your mobile network. However, the feature isn’t enabled by default and can only be switched on during a call – once it’s activated, it will remain so for future calls.
