AES3 (also known as AES/EBU) is a standard for the exchange of digital audio signals between professional audio devices. AES3 was jointly developed by the Audio Engineering Society (AES) and the European Broadcasting Union (EBU). An AES3 signal can carry two channels of PCM audio over several transmission media including balanced lines, unbalanced lines, and optical fiber. The standard was first published in 1985 and has been revised in 1992 and 2003.
AES3 has been incorporated into the International Electrotechnical Commission’s standard IEC 60958, and is available in a consumer-grade variant known as S/PDIF.
