Microsoft Details Audio, Skype, And Chat Improvements on Xbox One
On the controller side, the Xbox One Wireless Controller’s new expansion port expands the data transfer rate between the controller and console. It can both capture and render speech at 24KHz PCM, which is triple the rendering sample rate and a 50 percent capture rate improvement over Xbox 360 headsets. Moreover, the Xbox One's higher $499 price tag does at least include an Xbox One Chat Headset.
Of note, voice chat will require Xbox Live, while in-game voice chat and Skype require an Xbox Live Gold membership. So much for one-and-done on the wallet side, huh?
