Detect Silence
The Detect Silence function searches for silent sections in an event and either splits
the event, removing the silent parts from the project, or creates regions
corresponding to the non-silent sections.
• To open the Detect Silence dialog, select one or several audio events in the
Project window or the Audio Part Editor. On the Audio menu, open the
Advanced submenu and select “Detect Silence”.
If you select more than one event, the Detect Silence dialog allows you to
process the selected events successively with individual settings or to apply
the same settings to all selected events at once.
The settings have the following functionality:
Open Threshold
When the audio level exceeds this value, the function “opens”, i. e. lets the
sound pass. Audio material below the set level is detected as “silence”. Set
this value low enough to open when a sound starts, but high enough to
remove unwanted noise during “silent” sections.
Close Threshold
When the audio level drops below this value, the function “closes”, i. e. sounds
below this level are detected as “silence”. This value cannot be higher than
the Open Threshold value. Set this value high enough to remove unwanted
noise during “silent” sections.
Linked
If this checkbox is activated, the Open and Close Threshold values are always
set to the same value.
Min. time open
Determines the minimum time that the function will remain “open” after the
audio level has exceeded the Open Threshold value.
If the audio contains repeated short sounds, and you find that this results in
too many short “open” sections, try raising this value.
