AES/EBU

(Audio Engineering Society/European Broadcasting Union) A professional serial interface for transferring digital audio from CD and DVD players to amplifiers and TVs. AES/EBU is typically used to transmit PCM and Dolby Digital 5.1, but is not tied to any sampling rate or audio standard.

AES3 and AES3id - Short and Long Distances
AES3 uses 110 ohm shielded twisted pair (STP) cable with XLR connectors up to a distance of 100 meters. AES3id uses 75 ohm coaxial cable and BNC connectors for up to 1,000 meters. "Unbalanced" coax is better for long distances than "balanced" twisted pairs.

S/PDIF
S/PDIF is the consumer version of AES/EBU and uses a lower signal voltage. They both support the same audio data with slight differences in the frame bits. Conversion between these interfaces must be handled with electronic circuits, not by adapting one connector to another. See S/PDIF.


AES/EBU vs. S/PDIF
AES3 uses shielded twisted pair cables while the AES3id variation shares the same cable as the consumer-oriented S/PDIF interface.

AES3 describes a jitter tolerance test where the capability of a receiver to tolerate defined levels of interface jitter on its input is examined.
AES3, S/PDIF: In the consumer and professional audio field, digital audio typically is carried from point to point as a biphase coded signal, commonly referred to as AES3, AES/EBU, or S/PDIF.
For an AES3 signal, there are 32 bits per subframe and 64 bits perframe, giving a nominal 128 pulses perframe in the channel after biphase mark encoding is applied.
The UI is used for several of the jitter specifications in AES3.
Thirty-seven papers were submitted to NIST for consideration for AES3. Twenty-four of those papers were presented at AES3 as part of the formal program, and one of the remaining papers was presented during an informal session at AES3.
AES3 gave members of the international cryptographic community an opportunity to present and discuss Round 2 analysis and other important topics relevant to the AES development effort.
Moreover, the issue of quantitative review had been raised by the public at various times during the AES development effort (most recently at AES3), and there seemed to be little agreement regarding how different factors should be weighted and scored.

In contrast, AES67 only specifies the baseline connectivity of audio streams, and more closely resembles an audio-over-IP version of MADI or AES3. It focuses on how audio channels move through the network between points, without defining how routing or switch-defined control may occur.
