ASUS revealed the Xonar HDAV1.3 Series Sound Cards with world's first Dolby TrueHD Bit-Stream feature for the Blu-ray discs.
A combination comprising of C-Media’s custom-made AV200 audio processor and ArcSoft’s TotalMedia Theatre software player lets users be the first to enjoy Dolby TrueHD’s lossless compression rate of 24bit/192KHz over to their AV receivers.
The ASUS Xonar HDAV 1.3 is the world’s only solution capable of providing bit-to-bit exact lossless Blu-Ray audio output—without any downsampling to DVD quality—allowing users to enjoy next generation audio enhancements such as DTS-HD, Dolby TrueHD and Dolby Digital Plus on the PC. Furthermore, the Xonar HDAV 1.3 also supports most Video Graphics Cards on the market, allowing delivery of both video and audio outputs through a single HDMI cable.
