Calibrating the Kaleido-X
Multiviewer Input Calibrations
The following values are involved:
Parameter Description
Expected dialnorm Type your organization’s reference dialnorm value in the box, or set
it using the slider. The default value is -27 dB, on a scale of -60 dB to
0 dB. This value can then be compared against the measured
loudness, and against the encoded dialnorm found in the Dolby
VANC data.
Max. lower
deviation
The Max. lower deviation parameter determines the tolerated
excursion range below the reference value. The measured levels and
the encoded dialnorm can be compared against each other and
against your organization's expected dialnorm, and alarms
triggered in case of too much deviation. The default value is -5.4 dB,
on a scale of -64 dB to 0 dB.
Note: Setting this parameter to its lowest value (-64 dB) will
prevent the Loudness/Expected alarm from being triggered when
silence is detected.
Max. upper
deviation
The Max. upper deviation parameter determines the tolerated
excursion range above the reference value. The measured levels and
the encoded dialnorm can be compared against each other and
against your organization's expected dialnorm, and alarms
triggered in case of too much deviation.The default value is 2.4 dB,
on a scale of 0 dB to 15 dB.
Loudness standard Select the standard you wish to apply: either the A-weighted Leq
(LEQ(A)) or the ITU-R BS.1770 metering ballistics.
Note: Mixing standards for different inputs is not supported.
Loudness channel
selection
Select the check boxes corresponding to the audio channels that
should contribute to the loudness measurement.
Note: The current version of the Kaleido-X software can measure
loudness against a maximum of 8 channels. If you select more than 8
channels, only the first 8 will be used.
