AES11

Encyclopedia : A : AE : AES : AES11

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 methord 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.

This 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.
