An important condition for high quality recording is the selection of an optimal recording level. The i-Sound Recorder uses the VU Meter to display the signal level in decibels. It works all the time and allows you to adjust the signal before you start recording. If you are using automatic recording and cannot change the settings in time, you can activate the AGC system.
The VU Meter window is also used by the VOX system to display the threshold level as a small red line. In this way you can visually assess the correctness of the settings.
