AES53-2018: AES standard for digital audio - Digital input-output interfacing - Sample-accurate timing in AES47

Printing Date: 2018-08-02

Publication History: Published 2006; Reaffirmed 2011; Revised 2018; Reaffirmed 2023

Abstract: This document specifies how the timing markers specified in AES47 may be used to associate an absolute timestamp with individual audio samples. AES47 specifies a format for the transmission of digital audio over asynchronous transfer mode (ATM) networks. A recommendation is made to refer these timestamps to the SMPTE epoch which in turn provides a reference to UTC and GPS time.
