as depicted in Figure 25. Errors are expressed as the percentage
of a complete digital audio frame.
Notice the “No Reference Signal” message in Figure 25. It will

The AES11 standard specifies that synchronization errors should
be no greater than 25% of the audio sample frame. When the
synchronization error exceeds this limit, a SYNC ERR flag
