3. Advantages of USB Xear 3D Sound Solution
The 1st Advantage of Xear 3D™ Sound Technology: Virtual Multi-Channel Audio
SPEAKER SHIFTER allows the users to obtain a 5.1CH & 7.1CH virtual speaker
environment no matter what output device they are using (2CH speakers). Moreover,
the users are able to drag the virtual speakers to anywhere they want without moving
the actual ones to accommodate their need. Therefore, by dragging a specific virtual
speaker shown on the GUI to the preferred position, enhanced individual channel
output is feasible. This revolutionary technology is welcome by those who always
complain about the not-loud-enough volume of the center (for dialog) or bass output
in DVD. With Xear 3D™ SPEAKER SHIFTER, no more low-volume center and/or
bass output problems.
To remedy this, C-Media provides the patented Xear 3D™ filter, capable of providing
virtual 5.1CH & 7.1CH audio by means of a pair of speakers (2CH speakers to output
virtual 5.1CH or 7.1CH).
Xear 3D™ SPEAKER SHIFTER allows users to obtain comprehensive 5.1CH and 7.1CH
audio even though they are actually using a pair of speakers of 2CH speakers.
PS: 7.1CH was supported on WinXP OS and depend on device hardware capability.

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. C-Media
patented 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.

The 3rd Advantages of Xear 3D™ Sound Technology: Karaoke Functions
This function included microphone echo, magic voice, key shifting and vocal canceling.
No matter any sound source you playing, you can enjoy various singing way and feeling
like personal performance. General microphone control cannot prettify user’s voice but
by way of microphone echo, any one can get beautiful voice. Moreover, you can use
key shifting to adjusting any music and melody to harmony with your tune. Better yet,
vocal canceling can eliminating singer’s voice and make the song to be background
music for happy singing. Furthermore, magic voice not only can provide interest effects
but also can use on Internet voice communicate to keep anonymous. Especially for
applications with ICQ, MSN message, Yahoo message, VOIP phone and on line game

7. FAQ & Technical Support
Q1:Why play CD without sound ?
Most general case was digital CD playback function did not open. Because USB
audio is digital signal, it is use different path to process CD music with traditional
analog CD.
You should open “Device Manager”, select “DVD/CD ROM drives” and open it.
Then switch to “properties” page and enable digital CD audio.
Q2:Why sometimes Win98SE and WinME can not auto detect USB audio device
and switch?
Since Win98SE and Win ME have different driver architecture with Win2000 and
WinXP. When users plug in/out USB audio device too much time or faster, these
two OSs may not detect the change on device. So, sometimes user got to switch
audio device to USB audio device by them self.
While user plug in USB audio device on Win98SE and WinME system, if system
cannot switch audio device to USB, please open “Control Panel”, select “Sounds
23
C-Media Xear 3D Sound Solution For USB Multi-Channel User Manual Rev. 1.0
and Audio Devices”, choice “Audio” page then switch “Default device” to USB
Device or C-Media USB Device.
Q3:When using software application program (Like: Media player, Winamp,
PowerDVD, WinDVD….) to playback any media files, can I plug out USB
audio device while playing?
It is incorrect mode of operations, because while application programs were
playing audio stream, windows system is stilling using audio device to process
and deliver data real-time. So, when user plug out USB audio device windows
system can not delivering audio data to the same device, so that system will be
confused and make application programs failure or system crash.
The right way to plug out USB Audio device was stop playback function first.
Especially when your Windows system was Win98SE or WinME, this corrected
operation will keep stability of working system. Otherwise, uncorrected plug out
will cause application program or system crash.
24
C-Media Xear 3D Sound Solution For USB Multi-Channel User Manual Rev. 1.0
※ Do not plug out while application programs were playing media files. Please
stop playback before plug out USB audio device.
Q4:Xear 3D Sound technology provide amazing function In virtual 5.1 speaker
shifter, how to using this function in different media format?
Virtual 5.1 Speaker shifter can process 2CH, 4CH or 5.1CH audio format and
make 2CH audio file like MP3, stereo wave to transfer in virtual 5.1 surround
sound. However, the most perfect application is playing 5.1CH DVD content like
Dolby digital AC-3 and DTS. User can using physical 2CH device (earphone,
speaker) to enjoyed dynamic 5.1CH surround sound by moving graphic user
interface.
In general, when user buy a new computer usually got a free bundle software
DVD player like PowerDVD or WinDVD. Most of these free bundle software
version only provide 2CH DVD audio playback capability that because 5.1CH
decoding was more expensive. So that, when user playback real 5.1CH DVD
content it can not processing different 6 channel audio source to spread out
characteristic with each channel. If user wants to enjoy real 5.1CH DVD
surround sound, you can buy a software DVD player with Dolby digital AC-3 or
DTS 5.1CH decoding function.
※ User can check software DVD player to confirm what decoding version that
DVD software player supported.
1. Open Software DVD Player
25
C-Media Xear 3D Sound Solution For USB Multi-Channel User Manual Rev. 1.0
2. Click display windows
3. Click right key of mouse
4. Select “Configuration” or “Setup”
5. Choice “Audio” function setting page
6. Check “Audio Output”→If you can see or select speaker from 2 to 6 that
mean this version was supported 5.1CH decoding capability. Otherwise, it
is only supported 2CH decoding capability.

C-Media Xear 3D Sound Solution For USB Multi-Channel User Manual Rev. 1.0
or
Q5:What is 7.1CH listening environment and how different with 5.1CH?
1. The 7.1 channel mode is newest multi-channel audio format and technology in
the market. It’s include center, subwoofer, front left, front right, rear left, rear
right and back surround. This definition was the same as Dolby Lab. and DTS
Lab.
27
C-Media Xear 3D Sound Solution For USB Multi-Channel User Manual Rev. 1.0
2. This format is a new standard and not very much content has supported it.
The 7.1CH content was naming Dolby Digital EX by Dolby Lab. and DTS was
naming DTS-ES (Extended Surround).
3. The difference of 5.1CH and 7.1CH is additional 2CH. This 2 speaker was
placed on rear area and to enrich backward sound effects.
5.1CH Environment
7.1CH Environment
Q6:When can I use 7.1CH function and have any application note or limitation on
it?
1. If you using Microsoft default USB audio driver to process this device, the
7.1CH mode only can work on Windows XP operation system. Moreover, you
have to buy a 7.1CH DVD content with Dolby Digital EX or DTS-ES format
and use DVD software player to decoding this format.
2. If you using Xear 3D sound technology driver to process this device, no matter
any sound source you playback this driver can convert it to 7.1CH. This
function was virtual multi-channel effects and you can feel 7.1CH sound
effect on any devices, like earphone, 2CH speakers, 4Ch speakers, 5.1CH
speakers or 7.1CH speakers. But, if your want to listening real 7.1CH sound
effect that has to work on 7.1 audio device products and connected real 8
speakers.
