Audio Format
The format of each audio channel (PCM, Dolby AC-3, Dolby E, other or Unavailable) is
reported as a text attribute, that can be assigned to a text level within a logical source.
Audio Metadata
The metadata extracted from the VANC and from the Dolby E is available as text in the XEdit
hierarchical system list, and therefore can be exposed via any layout element capable of
displaying text levels from logical sources (currently only UMDs).
Dialnorm is displayed as a numeric value between -31 and -1 dB. Program Config is
displayed as the Dolby E Program Config description. Unavailable is displayed if the source
is not being decoded, or is not Dolby E.
Logical Source Assignment
Logical source assignment is performed by dragging an AES pair onto a logical source’s
audio level.
If the AES pair is calibrated as a Dolby E source, then the 8 channels are available to be
displayed by an audio monitor. The channel displayed by the audio monitor depends on
how the monitor was configured.
For Dolby VANC, if the audio monitor is set to Auto or Dolby VANC, the VANC metadata
from the video of the assigned AES will be decoded. The audio monitor will have access to
all amended audio peaks depending on VANC program configuration (regardless of which
AES pair was assigned to the logical source).
Microphone Loudness Measurement
Kaleido-X and Kaleido-X16 multiviewers are capable of providing microphone loudness
measurement as dynamic text values, for Audio Bridge Terminal (ABT) sources. Values are
available for every ABT channel, and can be displayed in a UMD (or in an alarm status
monitor), provided you configured logical sources with the appropriate text levels
Term Definition
Dolby E stream A coded (compressed) 8-channel digital stream that fits inside an AES
channel (L/R)
