45 ASUS Xonar D1
6.9 DS3D GX and DSP Modes
Xonar D1 is introducing an innovative technology –DirectSound D Game
Extensions v1.0 (DSD GX 1.0)- to restore DirectSound D Hardware acceleration
mode and its subsidiary EAX effects on Windows Vista for D games. Unlike some
proprietary API like OpenAL, DSD GX doesn’t require games to support OpenAL
API. All existing games compatible with Microsoft DirectX and DirectSound D/D
will be supported with DSD GX technology. Before you start EAX and DSD HW
games, please enable DSD GX on the Xonar D1 audio center, and disable the
function after the games.
Supports latest DS3D GX 2.0 for gaming on Vista & XP
DSD GX .0 not only revives EAX and DirectSound HW effects, but also
allows you to run EAX HD 5.0 games on both XP and Vista. It provides the best
compatibility with existing DirectX games. GX.0 also adds innovative VocalFX
voice effects for existing EAX games or VOIP applications.
Besides the abundant sound effects described above, the Xonar D1 also provides
quick Digital Sound Processing modes which are configured for typical applications
including Music, Movies, and Games over different output speaker types. In
addition, Xonar D1 also offers a Hi-Fi mode for hi-fidelity playback without any
effect processing to keep the original audio fidelity. Every time you turn on Hi-Fi
mode, Xonar D1 will clear all sound effects. It’s also recommended to use Hi-Fi
mode for audio quality tests (using RMAA software or another machine-based
measurement). Use the DSP mode button as the quick setup if you don’t wish to
know the details of the effect setup. (Note: no sound effects will be applied to high-
definition 96KHz/192KHz content.)
