Audio quality of recorded messages is very poor and has a high frequency sound in the background. What can I do?
The input Volume on your CURL telephony card may be set too high. By default it is set to 8.
- Click start -> All programs -> Easy Tapi -> Line detector
- Then click Settings -> Volume Settings and select the channel you are recording from.
- Change the Input volume from 8 down to a lower level. 0 works Good.
This will reduce the background noise and stop the high frequency.
