AES 53-2006 (R2011) PDF Download

AES 53-2006 (R2011) is a standard that focuses on achieving sample-accurate timing in AES47, which is another standard for digital audio input-output interfacing. AES47 primarily deals with the transmission of digital audio over asynchronous transfer mode (ATM) networks. The purpose of AES 53-2006 (R2011) is to specify how timing markers, as defined in AES47, can be used to associate an absolute timestamp with each individual audio sample.

This standard recommends referring the timestamps to the SMPTE epoch, which provides a reference to Universal Coordinated Time (UTC) and Global Positioning System (GPS) time. By synchronizing audio samples with an absolute timestamp, sample-accurate timing can be achieved, ensuring that audio data aligns precisely with time markers.
