Level meter

Element	Description
Status	Non-editable information field. Shows current audio input status.
Measurement interval	Sets the time in miliseconds after which the level measurement is updated.
Peak fall-off rate	Sets the speed in decibels per milisecond for how fast the displayed audio level in the visual level meter drops after a peak.
Peak hold time	Sets the time in miliseconds for which a peak is displayed in the visiual level meter.
Enabled	Toggles the level measurement “On" or “Off”.
Level monitoring	Toggles the level measurement “On" or “Off”. When “On”, warnings and errors are triggered based on the following settings.
Inactive threshold	Sets the dB level under which the audio is considered “silent”.
Active threshold	Sets the dB level above which the “silence” is considered over.
Hold Time	Sets the time in seconds that the level needs to be below the Inactive Threshold before “silence” is detected.
Warning Timeout	Sets the duration of “silence” in seconds after which a warning notification is triggered. This notification is also written into the Log.
Error Timeout	Sets the duration of “silence” in seconds after a warning notification has been triggered until an error notification is triggered. This notification is also written into the Log.
Stop Pipe after error timeout	Toggles whether the PIPE is stopped after an error timeout (see option above) is triggered. When “On”, stop on error is enabled.
Set alarm on timeout	Toggles whether a warning or error timeout is displayed in the UI. When “On”, it is displayed.

!	Level meter sink
	Unusually for an audio processing element, you can create a valid PIPE ending in a level meter element (i. e. without a sink element). This is used to create a PIPE for monitoring audio levels and silence detection.
