5.4.5 Audio - Loudness
Loudness measurement is available in Kaleido-Solo model 910 only.
The Kaleido-
Solo supports two independent loudness measurements, called “1
st
Loudness” and “2
nd
Loudness”. You
can configure both in this menu. Having two separate measurements is useful if, for example, you want to measure
one 5.1 and one stereo pair simultaneously.
1st Loudness/2nd Loudness - Program Selection
Manual
Use to manually set the coding mode and the channel selection.
Prog. 1
Use the Dolby metadata contained coding mode and channel selection of program #1.
...
Prog. 8
Use the Dolby metadata contained coding mode and channel selection of program #8.
Note that loudness meters can, under some conditions, be unable to display loudness information.
For instance, if one of the loudness audio channels involved is not PCM, an error message will be
displayed and no loudness data will be shown. The same thing will happen if the audio program selected
(and its associated audio coding mode) is extracted from Dolby Metadata and none can be found on
input. An error message saying “no Dolby” will show up to explain why no data is being processed.
