May 12 - 2:40pm EDT   Creative expanded its lineup to the underserved notebook audience with the Sound Blaster X-Fi Surround 5.1. The USB device is claimed as the first to both boost audio quality and output in full 5.1-channel surround sound; Dolby and DTS movies, as well as games that support surround through DirectSound or OpenAL, automatically have their video processed and split across a speaker setup. Compressed audio is also cleaned up through the Crystalizer hardware that Creative says restores lost details. [full story]

April 10 - 10:10am EDT   DTS today said one of the longstanding criticisms of the PlayStation 3 would be addressed with a firmware update next week that adds DTS-HD Master Audio for movies on the Sony game console. The addition allows Blu-ray movies and other HD titles to output 7.1-channel surround at a 96kHz, 24-bit quality at up to 24.5 megabits per second. At this rate, the stream virtually equals the sound created in the studio masters that give the DTS format its namesake, according to its creator. [full story]
