40 ASUS Xonar DG
6.9 DS3D GX and DSP Modes
Xonar DG is introducing an innovative technology –DirectSound 3D Game
Extensions v2.5 (DS3D GX 2.5)- to restore DirectSound 3D Hardware acceleration
mode and its subsidiary EAX effects on Windows Vista for 3D games. Unlike some
proprietary API like OpenAL, DS3D GX doesn’t require games to support OpenAL
API. All existing games compatible with Microsoft DirectX and DirectSound 2D/3D
will be supported with DS3D GX technology. Before you start EAX and DS3D HW
games, enable DS3D GX on the Xonar Audio Center, and disable the function after
the games.
In addition, Xonar DG 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 DG 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.
No sound effects will be applied to high-definition �6�Hz�1�2�Hz content.
