Best known for its work on the MP3 format, Fraunhofer this afternoon said it would use Mobile World Congress next week to formally roll out two new audio formats specially designed for mobile. MPEG Surround can produce as much as 7.2-channel surround sound but has no real effect on the bitrate versus a stereo mix. A smartphone or a networked media hub using MPEG Surround can get the full audio of a movie without needing more space or a faster network connection.
