From this window, you can specify the level of Line Volume (the amplitude of the data coming to webcamXP
from the Microphone itself and the Mic Volume (the amplitude of the data being registered in webcamXP from
the connected camera). You may also use the slider bars located above each volume option specify a speaker
bias. For example, a slider to the left will cause the sound to appear as if they are only coming from the left-
hand speaker.
6.2.2 Specifying an Audio Threshold
Located to the left of the Audio Detector tab is a line graph box containing a progress bar and a slider bar.
The slider bar is designed to allow you complete control over the detector’s sensitivities. The higher the bar,
the more sensitive the audio detector will be, and thus the more events it will trigger. The lower the bar, the
less sensitive the audio detector is created.
To specify a threshold, simply move the slider to the left or right until the correct sensitivity is selected. If you
wish to test sensitivity as you go, begin by enabling audio detection. The strength of the audio signal at any
given time is shown in a line graph (shown in the screenshot above). As you move the slider, the sensitivity of
the detector is automatically altered, causing a noticeable difference in the behavior of the line graph.
