Chapter 4: Audio Center

Essence STX II introduces 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 does not 

require games to support OpenAL API. All existing games compatible with Microsoft DirectX and 

DirectSound D/D are supported with DSD GX technology. Before you start EAX and DSD HW 

games, enable DSD GX on the Xonar Audio Center, and disable the feature after playing.

DSD GX .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. GX.0 also adds innovative VocalFX voice effects for existing EAX games or VOIP 

applications. Besides the abundant sound effects described above, the Essence STX II 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, Essence STX II 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/19KHz content.
