The Voice Monitor view displays the volume of voices and their envelope (if available).
To understand and debug the HDR system:
Open the Voice Monitor view.
Drag your HDR bus into the view's context.
Set the Mode to either Bus input or Bus output. Bus input mode displays voice levels in decibels as seen by the HDR bus, before the HDR compression, while Bus output mode displays them at the output of the HDR bus, after HDR compression and the bus output gain. Most figures in this document are screenshots of the "two sides" of the Voice Monitor view.
