Calibrating Dolby E Audio Metadata
Notes

per input card. See “Enabling Options” on page 359.
• Dolby E decoding is not yet supported on the Audio Bridge Terminal (ABT).
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.
Loudness Channel Selection Select the check boxes corresponding to the audio channels that should contribute to
the loudness measurement.
Loudness Standard Select the standard you wish to apply: either the A-weighted Leq ( LEQ(A) ) or the ITU-R
BS.1770 metering ballistics.
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.
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.
