DS3D GX and DSP Modes

Xonar DG SI use the DirectSound 3D Game Extensions v2.5 (DS3D GX 2.5)
technology to restore DirectSound 3D Hardware acceleration mode and its
subsidiary EAX effects on Windows 7 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 SI 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 SI will clear all sound effects. 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 do not wish to know the details of the
effect setup.
No sound effects will be applied to high-definition 96KHz/192KHz content.
