Audio LKFS Monitor

Note: • This function provides only LKFS monitoring as described here; this function does not provide active LKFS correction.
Selected channels are passed through the card unaffected by settings made for this function.
• The Audio LKFS Monitor target LKFS uses the Dialnorm value setting per the received selected external metadata (or
per the internal metadata settings where used). See Appendix A, "Loudness Measurement Guidelines and Techniques"
for more information about LKFS parameters and measurement techniques. Read and understand the information
in this appendix before changing LKFS parameters from default values.

Provides an ITU-R BS.1770-1 / ATSC A/85 Audio
Loudness (LKFS) measurement of selected channels
comprising the L, R, C, Ls, and Rs channels of a
5.1-channel complement. Also provide a configurable
alert if summation LKFS result exceeds configurable
thresholds.
Separate drop-down lists for Left, Right, Center, Left Surround (Ls),
and Right Surround (Rs) for applying any combination of card audio
outputs to each of the five LKFS monitor inputs as shown below.
Note: Set any unused LKFS monitor channel inputs to Silence.
The example below shows selection from various channel sources
applied to the LKFS monitor inputs. Because the LKFS monitor uses
output (post-processed "destination") channels, LKFS under/over
conditions can be corrected using the Dashboard™ controls for the
monitored channels. (Dolby
to the Dolby encoder inputs.).
Displays the current aggregate ITU-R BS.1770-1 LKFS loudness for the
selected monitored channels.
Note: -inf LKFS display indicates LKFS monitor is not receiving any input
(for example, as in the case of intended channels not being "seen"
by the LKFS monitor due to desired embedded channels being
directed to AES output and not embedded output channels).
