Have you loaded up one of the leaked BlackBerry OS 10.2 builds lately? If you conducted a BBM Voice or Video call you might have noticed a small white icon in the top-left corner of the screen.

This icon says ‘BlackBerry Natural Sound’. BlackBerry Natural Sound is new technology exclusive to BlackBerry and part of BlackBerry 10 OS version 10.2 that makes BBM Voice and BBM Video chats sound more natural and realistic.

BlackBerry Natural Sound lets you hear nuances and variations in tone, making conversations sound like you’re in the same room. The newly announced BlackBerry Z30 smartphone comes with stereo speakers that immerse you in your music, videos, apps and games, and makes conversations sound like you’re face-to-face.
