Maybe you meant "Word clock"?

Try Google.

AES11
From Wikipedia, the free encyclopedia

The AES11 standard published by the Audio Engineering Society 
provides a systematic approach to the synchronization of digital 
audio signals. Recommendations are made concerning the accuracy of 
sample clocks as embodied in the interface signal and the use of this 
format as a convenient synchronization reference where signals must 
be rendered co-timed for digital processing. Synchronism is defined, 
and limits are given which take account of relevant timing 
uncertainties encountered in an audio studio. AES11 Annex D (in the 
November 2005 or later printing or version) shows an example method 
to provide isochronous timing relationships for distributed AES3 
structures over asynchronous networks such as AES47 where reference 
signals may be locked to common timing sources such as GPS. The AES11 
standard may be studied by downloading a courtesy copy at the AES 
standards web site as AES11-2003 with the current version (or 
printing) dated 2005-11-21. In addition, the Audio Engineering 
Society has now published a related standard called AES53, that 
specifies how the timing markers already specified in AES47 may be 
used to associate an absolute time-stamp with individual audio 
samples. This may be closely associated with AES11 and used to 
provide a way of aligning streams from disparate sources, including 
synchronizing audio to video in networked structures.
