[MWC] Sound is increasingly becoming an important feature in mobile devices, and it’s no surprise that audio industry giants like Dolby are getting into the game. At the Mobile World Congress this week in Barcelona, Spain, Dolby will be demonstrating the latest handsets that utilize Dolby technologies. This includes the Nokia E7, LG Optimus Black, and other handsets from HTC, Acer, Fujitsu and ZTE. Just like high-definition video, high-definition audio is slowly becoming a standard instead of a niche feature for audio purists. Dolby will be showing off Dolby Digital Plus (5.1 surround sound over headphones), Dolby Pulse (quality audio over limited at low bit rates), Dolby Mobile (virtual surround sound without headphones), Dolby Media Generator (content optimization for faster delivery and higher playback quality) and Dolby Voice (technology to provide clear, consistent voice communications regardless of environmental noise). We’ll be checking out what Dolby has to offer at MWC, so stay tuned for more details.
