If language groups are used
You can have multiple tracks and output channels with the same label. If multiple tracks have the
same label, AppCenter evaluates where to map the tracks as follows:
• An output channel’s primary and secondary output labels are considered together as a “language
group” when assigning an audio track for playout. If two channels have the same primary label
but have different secondary labels, then those channels have different language groups. For
example, a channel with labels FRE+ GER is considered a different language group than a channel
with labels FRE + ENG.
• Each output channel, in order from first to last, is evaluated to determine if the label or language
group matches a labeled audio track in the clip. The first channel with a label or language group
that matches the track label plays that audio track. If the clip has several audio tracks with the
same label, the first matching output channel plays the first audio track, the second matching
output channel plays the second audio track, and so on.
• The Play Silence box. If the AppCenter does not find a matching label or language group for the
output channels, and the Play Silence box has been checked in Configuration Manager, the
channel plays silence. Otherwise, if AppCenter finds no match, the output channel plays the
correspondingly numbered audio track.
This evaluation process is further described in the following sections:
• If the primary output alone is labeled
• If both primary and secondary outputs are labeled
• If no output labels match the track labels
• If Play Silence if checked
• If Play Silence is not checked
If the primary output alone is labeled
If the output routing channels are assigned primary labels, AppCenter evaluates the labels to see if
they match with the track labels in the clip as follows:
• If there are no secondary labels assigned, then only the primary labels are evaluated.
• Labels are evaluated in numerical order, that is, from the first to last.
• After labels are evaluated in numerical order, the Play Silence check box is evaluated to determine
if it is checked or un-checked.
