7. Audio Channel Labels – The audio channel labels can be numbered in channel pairs
(1,2,3…) or can be configured to show the surround channel labels (L, C, R, Ls, Rs,
Lfe..). The audio program config within the audio input/outputs configuration menu
defines the audio mappings ( 8x1 (Mono), 4x2 (Stereo), 2x3 (LCRS), 2x2 2 (Quad),
2x3.1 (LCRLfe), 5.1 + 2 (Surr + Stereo), 7.1, 2 + 5.1 ( Surr). These audio
program configuration define the number of programs present within the audio bars and
how to sum the audio channels within the program. The audio channel labels below the
audio bars indicate whether this channel is included within the audio Loudness
summation. A Green channel label indicates that the audio channel is included in the
Loudness summation. Whereas a White channel label indicates that the audio channel
is not included in the Loudness summation. The summation of the number of channels
can be configured by the user within the Loudness Settings menu.
8. Audio Program number - Specifies the audio program currently being used for the
program loudness. Within the
Config
menu the audio program can be configured by the
user for AES or Embedded inputs and configured automatically for Dolby streams
based on metadata. For instance stereo would use a Audio Program Config of 4x2
(Stereo) providing 4 different stereo program (1-4) for the 8 audio bars.
9. Audio Ballistic - Specifies the response characteristics of the level meters. Choices are
True Peak, PPM (Peak Program Meter) Type 1, PPM Type 2, VU, and Loudness.
10. Loudness Ballistic - Specifies the response characteristics of the Loudness meters.
Choices are Short Average, Long Average, Ungated Long, IEC 61672 F, IEC 61672 S
and EBU R128 M (Momentary).
