Preferences – Media Quality
Audio Quality

Reduce background noise Automatically attempts to remove background noise. Typically on for the speakerphone.
Automatic gain control This feature is typically on.
Preserve bandwidth When this feature is on, X-Lite stops sending audio when you are not talking.
When this feature is off, X-Lite always sends audio, which uses more bandwidth but may result
in better call quality.
Typically off. However, if you are using a slow (dial-up or ISDN) connection, you may want to
turn it on.
Volume Control Choose the setting that suits your setup.
Video Quality
Enable this option Check or uncheck to flip the video image.
Resolution Leave at standard, or change the size as follows:
• Set it to high if you have a good camera and a computer with a fast CPU. You will know that
you have set the size too large if:
Your computer slows down (the video is using too much CPU)
The video shows black areas or is slow or jerky.
• Typically set it to low only in special situations, for example, when using wi-fi in a hotel. You
will know that you have set the size too small if the video is fuzzy.
