ASUS Xonar Essence ST 

Xonar Essence ST introduces 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 feature after playing.

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.
