The most common adjustment you may want to make on audio playback or recording is the volume level. You can open the Volume Control window shown in Figure 13.11 from the Start menu (Start Programs Accessories Entertainment). The Options Properties command opens a window where you can add additional volume sliders to the Volume Control window for individual sources and destinations, such as a microphone or a CD player.
Figure 13.11: The sliders on the Volume Control window set input and output levels for audio signals.
The horizontal Balance sliders in each column control the relative level of the audio to or from the left and right channels.
