Synchronization Lost Event
This event is generated when the system is in Referenced Mode after a successful initial Test ID recognition (see "Synchronization") and encounters unexpected frequencies or durations of audio segments while analyzing a received Reference Audio file. If this situation occurs, the internal segment tracking logic attempts to look forward and/or backward in the test script to determine if the currently measured characteristics are consistent with the previous or next segment of the script. If there is a match, the internal segment pointer is advanced or retarded appropriately, the Synchronization Lost event is not generated, and the audio analysis continues. However, if a match cannot be found, the system declares itself out of sync and generates the Synchronization Lost Event, terminates any active test script, and reverts to Non-Referenced Mode.
The information reported with the Synchronization Lost event is listed below:
- Info1: An integer reason code such as 12=Unexpected Frequency.
- Info2: Unused.
- Msg: Contains a diagnostic message containing a code point indicator, the SegmentID of the script that was expected when the error was declared, and the zero based index into the Segment Array.
