34 ASUS Xonar Essence ST
DS3D GX and DSP Modes
Xonar Essence ST is introducing an innovative technology –DirectSound 3D Game
Extensions v1.0 (DS3D GX 1.0)- 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 does not require games to
support OpenAL API. All existing games compatible with Microsoft DirectX and
DirectSound 2D/3D are 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.
Supports latest DS3D GX 2.0 for gaming on Vista & XP
DS3D GX 2.0 not only revives EAX and DirectSound HW effects, but also allows
you to run EAX HD 5.0 games on both Windows ® XP and Vista. It provides
the best compatibility with existing DirectX games. GX2.0 also adds innovative
VocalFX voice effects for existing EAX games or VOIP applications.
Besides the abundant sound effects described above, the Xonar Essence ST also
provides quick Digital Sound Processing modes that are configured for typical
applications including Music, Movies, and Games over different output speaker
types. In addition, Xonar Essence ST 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 HDAV 1 clears 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 are applied to high-definition 96KHz/192KHz content.
