DS3D GX and DSP Modes
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.
Supports latest DS3D GX 2.0 for gaming on Windows® Vista and Windows® XP
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.
