This is a signal level metering object to monitor and display RMS signal levels on the screen. This is a true RMS meter and as such uses more DSP resources than other meters.
Enable Control Output: Adds an output to the meter which follows the input.
Attack time control: Adjusts how the meter responds to short duration transients.
Release time control: Adjusts how long the meter takes to recover.
Reference: Sets the reference level for 0dB
