In iOS 7, Apple introduced a feature called FaceTime audio that offers sound quality that is far better than anything we had ever experienced before on the iPhone. It makes people’s voices sound more like, well, people’s voices. FaceTime audio works just like regular FaceTime calling; you can make a call to anyone with an iOS device that’s running iOS 7, and it’s completely free because it uses your data plan or Wi-Fi to make calls. Taking advantage of FaceTime audio is easy, since it is built into the operating system. However, Apple doesn’t automatically switch phone calls to FaceTime audio calls as it does with iMessages (likely because of potentially high data usage). As a result, people might not be aware of the new feature or how to use it. How do you do it? From within the Contacts or the Phone app, simply tap on the phone icon next to FaceTime and you’ll be connected right away. Read the full story at Boy Genius Report.
