D*AP LM 4

 

 

While the source for that trigger is a parameter source : 

 

 
 

Web GUI – EVENTS – Action Events – Loudness Measurement 

 
The EBU R128 implements the possibility to start, pause / continue, reset a loudness measurement.  
 

 

The example above defines two action events "Start" and "Stop". They will be triggered by : 
"Start Loudness Measure" and "Stop Loudness Measure" which have been setup 
previously on the trigger pane : 
 

 
While the source for those two triggers are GPI #1 and #2
