Choosing the Record Level

The bar graphs displayed on the right side of the Record dialog show the instantaneous peak levels of the input signal (expressed in logarithmic units called decibels). While the volume meters are running (they can be activated by means of pressing the PAUSE button prior to recording), you can adjust the record level of the audio card either directly (manually) or using the appropriate Windows tools supplied by the manufacturer.

The red indicators placed at the top of each bar-graph light up each time the input signal is clipped. Clipping occurs when the input level is too high. Since it results in audible signal distortions it should be avoided at all times.

Setting record levels too low is also disadvantageous, as it tends to decrease the signal-to-noise ratio.
