Detect Silence

You can make the following adjustments:
• With the zoom slider below the waveform to the right, zoom in and out on the
waveform.
You can also click in the waveform, keep the mouse button pressed, and
move the mouse for zooming. Move the mouse down to zoom in and move it
up to zoom out.
• If you have zoomed in on the waveform, it may not be completely visible
anymore. In this case, the scrollbar to the left of the zoom slider allows you to
scroll through the waveform.
You can also use the mouse wheel for scrolling through the waveform.
• If the Linked option in the Detection section is deactivated, you can use the
green square at the beginning and the red square at the end of the audio file
to graphically adjust the Open and Close Threshold values (respectively).
When “Linked” is activated, you can use either square to adjust both values.
The Open and Close Threshold values in the Detection section reflect these
changes.
