The 2nd Advantages of Xear 3D™ Sound Technology: Environment FX™ and
3D Positional Audio
In the real world sounds travel directionally; furthermore, sounds would have myriad
manifestations according to different factors of the environment: the room size,
distance, reflecting materials, obstructing objects, etc. For example, same footsteps
in different settings, say the cave and the sewer pipe, will generate distinctive effects
to the ears. In that regard, besides eye perception, sound cues also play an important
role in helping people tell the changes of the surroundings.
Regarding 3D VR(Virtual Reality) implementation, not only actual 3D visual images
are concerned, but what people would hear in the real world is count as well. One of
the major 3D VR implementations is 3D gaming for PC. When a command for 3D
audio is given, Microsoft operation system would provide DirectSound3D, an interface
conversion technology, to function as the bridge interfacing the upper application
program and lower audio device. Even so, it should be noted that only when the
lower audio device has 3D engine could the upper application program activate 3D
effects. Hence, if audio device does not provide 3D engine, no real-time audio effect
conversion (sound effects in different settings) is feasible. The gaming effect is thus
seriously destroyed.
As previously explained, in the process of real-time simulation of visual and acoustic
elements, powerful HRTF 3D engine and EnvironmentFX™ are a must. Xear 3D™
Engine excels all other solutions in that Xear 3D™ Engine supports powerful
HRTF(Head Related Transfer Function) 3D audio and real-time EnvironmentFX™,
exhibiting comprehensive and supreme environmental audio effects. When Xear
3D™ Engine is utilized, game players can instantly perceive different sound effect
when the setting is changed. No more confusion in directions.
