8. Crystal 3D Audio - CWB3DSND.EXE
The 3D audio accessory allows you to control the 3D audio features of your audio system. Depending on the specific audio device in your system you may have SRS® 3D Audio or QSound™ 3D Audio. The accessory runs each time you start your computer where it appears in the notification area of the task bar. The task bar is where the start button resides. The notification area is where the clock normally appears on the task bar. The accessory is activated by clicking with the left mouse button on the SRS or QSound logo in the notification area (If you have trouble finding the accessory, move the mouse over each icon in the notification area until you find the icon with a tool tip that says "Crystal SRS 3D Audio" or "Crystal QSound 3D Audio"). You can also click on the logo with the right mouse button to see a menu with options for activating the control "Settings", viewing the about box "About", or exiting the accessory "Exit".
Note: If for some reason the Crystal 3D Audio icon is missing, you can run it by choosing Programs | Accessories | Multimedia| Crystal 3D Audio Control from the Start menu. If you still do not see the 3D audio Icon it may be that the chip you have installed does not support 3D. Only the CS4237B and CS4238B chips support 3D audio.
Controlling your 3D audio
There are two sliders for controlling the sound of your 3D audio: on SRS systems they are labeled Center and Space, on QSound systems they are labeled Volume and Space. Moving the slider toward the plus sign increases the effect, moving the slider toward the minus sign decreases the effect. You may find that you prefer different settings for different types of music. You can save up to 3 configurations using the preset buttons. You can disable your 3D audio by un-checking the Enabled check box at the bottom of the accessory.
The 3D audio accessory provides three preset buttons, labeled 1, 2, and 3, that allow you to save your favorite 3D audio settings. To activate the settings click on the preset button with the left mouse button. To store your settings, change the description of the button that appears in the tool tip, or to restore the button to the factory defaults click with the right mouse button on the preset button to see the menu of options.
9. Crystal Digital Assisted Joystick
The Crystal Digital Assisted Joystick must be manually enabled for proper Digital Joystick configuration. This can easily be done by opening the Joystick Properties in the Control Panel and selecting the Joystick configuration to Crystal Digital Assisted Joystick.
