ASUS Xonar HDAV 1.3
6.9 DS3D GX and DSP Modes
Xonar HDAV 1.3 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 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 HDAV 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 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 HDAV 1.3 also
provides quick Digital Sound Processing modes which are configured for typical
applications including Music, Movies, and Games over different output speaker
types. In addition, Xonar HDAV 1.3 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 will clear all sound effects. It’s also recommended
to 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
don’t wish to know the details of the effect setup. (Note: no sound effects will be
applied to high-definition 96KHz/192KHz content.)
