A few days ago, Apple released iOS 16.4, a new version of its mobile operating system. If you have a compatible iPhone, we highly recommend that you update to the new system, because in addition to fixing bugs, those from Cupertino have included a curious feature that will improve the sound of your calls. To do this, they rely on technology included with FaceTime since iOS 15, so you can take advantage of it.
With iOS 15, Apple introduced Speech Isolation and Wide Spectrum audio options. With these, the company gave us a wider configuration in terms of the sound quality we could transmit with our microphone, and whose settings are compatible with different applications. Now, iOS 16.4 allowed this feature to also reach callsand you can use them to greatly improve their quality.
When you activate it Voice isolation iOS 16.4 will reduce the ambient sounds of the place you are in, amplifying the sound of your voice so that the other person can hear you clearly. Thus, if you are talking in the park or on the street, the barking of dogs or the sound of cars should not interrupt your conversation.
On the other hand, a wide range is useful if more than one person is talking on the phone next to you. This function amplifies the surround sound, the complete opposite of voice isolation. For this reason, it is not recommended to activate it if you are away from home or in a noisy environment.
How to Improve Call Sound with Voice Isolation on Your iPhone with iOS 16.4
This function It can be activated as soon as we start a conversation. Also, the settings will remain the same until you decide to turn them off manually.
- Start or answer a call from your iPhone running iOS 16.4.
- Now swipe from the top right corner to open Control center.
- Click above Microphone. A new menu will appear here.
- Choose from the options voice isolation.
After completing the steps, iOS 16.4 voice isolation will already be activated in calls on your iPhone. If you want to return to the previous mode or want to activate the wide spectrum mode, you just need to follow the previous steps again.
Apart from this new feature, iOS 16.4 also introduces other changes and improvements. Between them a whole new wave of emojipush notifications in Safari and fixes for crash detection on iPhone 14 and iPhone 14 Pro.
