AES11-2009, Synchronization of digital audio equipment
AES11-2009, AES recommended practice for digital audio engineering - Synchronization of digital audio equipment in studio operations has been published, 2009-06-01.
This revised standard 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 cotimed for digital processing. Synchronism is defined, and limits are given which take account of relevant timing uncertainties encountered in an audio studio.
In this revision, the relationship with AES5 has been clarified, with tolerances specified only in AES11 and nomenclature for multiple rates only in AES5. The subclause on video referencing (4.5) and Annex B (Word Clock) have been revised to more accurately reflect the current situation in the field. Annex D has been added.
