Detect Silence
274
Min. time closed
Determines the minimum time that the function will remain “closed” after the
audio level has dropped below the Close Threshold value.
Set this to a low value to avoid removing sounds.
Pre-roll
Allows you to cause the function to “open” slightly before the audio level
exceeds the Open Threshold value. In other words, the start of each “open”
section is moved to the left according to the time you set here.
This is useful to avoid removing the attack of sounds.
Post-roll
Allows you to cause the function to “close” slightly after the audio level drops
below the Close Threshold value.
This is useful to avoid removing the natural decay of sounds.
Add as Regions
“Add as Regions” will create regions according to the non-silent sections.
If you activate the “Add as Regions” option, you can specify a name for the
regions in the Region Name field. In addition to the name, the regions will be
numbered, starting with the number specified in the “Auto Number Start” field.
Strip Silence
“Strip Silence” will split the event at the beginning and end of each non-silent
section, and remove the silent sections in between.
Process all selected Events
If you have selected more than one event, you can activate the “Process all
selected Events” checkbox to apply the same settings to all selected events.
Compute
The audio event is analyzed, and the waveform display is redrawn to indicate
which sections are considered “silent” according to your settings. Above the
Compute button, the number of detected regions is displayed.
Auto
If you activate the Auto checkbox next to the Compute button, the audio event
is analyzed (and the display is updated) automatically every time you change
the settings in the Detection section of the dialog. Deactivate this option when
you are working with very long files, as this process might take some time.
Adjustments in the waveform display
The upper part of the dialog displays a waveform image of the selected audio event.
In case you have selected several audio events, the waveform of the event that you
have selected first is shown.
