AES/EBU

The digital audio standard frequently called AES/EBU, for Audio Engineering Society / European Broadcasting Union, that is officially known as AES3, was first published in 1992 as a standard (and revised in 1995, 1998, and 2003) for carrying digital audio signals between various devices.
The AES3 standard parallels part 4 of the international standard IEC 60958. Of the physical interconnection types defined by IEC 60958, three are in common use:
- IEC 60958 Type I Balanced - 3-conductor, 110-ohm twisted pair cabling with an XLR connector, used in professional installations (AES3 standard)
- IEC 60958 Type II Unbalanced - 2-conductor, 75-ohm coaxial cable with an RCA connector, used in consumer audio
- IEC 60958 Type II Optical - optical fiber, usually plastic but occasionally glass, with an F05 connector, also used in consumer audio
F05 connectors, 5mm connectors for plastic optical fiber, are more commonly known by their Toshiba brand name, TOSLINK. The precursor of the IEC 60958 Type II specification was the Sony/Philips Digital Interface, or S/PDIF. For details on the format of AES/EBU data, see the article on S/PDIF.
Other AES3 transport structures.
AES3 digital audio format can also be carried over an Asynchronous Transfer Mode network. The standards for packing AES3 frames into ATM cells is AES47 also published as IEC 62365.
