Volume-Triggered (VOX) Recording
Figure 23: The Volume-triggered (VOX) recording
shortcut menu.
To open the
VOX setting
dialog (Figure 24), click
Setup
of
the
VOX recording
shortcut menu (Figure 23).
With this mode enabled, the recording process begins as soon as volume level reaches the specified
threshold (triggering threshold). To make the process of threshold setting more convenient, the application
features an indicator displaying the
Current signal level
. The indicator marks when the signal reaches the
threshold.
The Volume-triggered recording mode (VOX) operates only left channel signal sources. If source
signal for the left channel is not set, the application will display the error message in the area
3
(Figure 18) and the recording will not begin.
Figure 24: The Volume-activated recording dialog.
Use
VOX threshold
slider to set the recording threshold.
Use the
Off delay, s
slider to specify the time during which the
device will keep on recording after the volume level falls down
below the triggering threshold. The set value is shown in the
title: the default value is 10 seconds.
