Error Code:
AudioChannelLabelUnknown (An analysis was unable to be completed because it was not able to determine audio channel labels)
Error Message:
Unable to determine audio channel labels.
Definition:
Our inspections were unable to determine the audio channel labels for your audio file's configuration/layout. This is typically due to an abnormal and incorrect channel configuration/layout being provided (e.g. a 4-channel delivery).
Solution:
Re-encode the file using a properly labeled channel configuration supported within our delivery specifications.
