Why should you have to listen to a sports commentator who's obviously pulling for the other team -- or one who's just plain boring? That's the question Dolby's out to answer with its personalized audio demo here at NAB. The company's showing attendees how they could enjoy a TV experience tailored to their preferences. Following through with the sports example mentioned above, this means different options for commentators during a hockey game. If you're a basketball fan watching the Spurs take on the Pacers while talking with friends on Skype, the system will recognize the VoIP service and mute other audio when they're speaking. Maybe you're more into The Voice; Dolby's tech could bring you audio from your favorite judge, excluding the opinions you don't want to hear.
