Audio LKFS Monitor
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.
Note: 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.
• Monitor Channel Selection 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. For stereo
LKFS monitoring, use the Left and Right channels and set the other 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 values displayed
can be post-loudness processed values.
• Measured Loudness Display
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).
