AES3 is the technical name for the professional digital audio standard better known as AES/EBU.

What is AES/EBU?

The name AES/EBU comes from the collaboration between the two organizations that created it: the AES (Audio Engineering Society) and the EBU (European Broadcasting Union).

It is a standard interface for reliably transmitting digital audio between professional equipment. Its main features are: Two Channels: Transmits two audio channels (a stereo signal) through a single cable. High Resolution: Supports audio with up to 24 bits depth and sampling frequencies up to 384 kHz. Embedded Data: In addition to audio, the signal also carries synchronization information (clock), status, and other control data. Robust Connection: Uses a balanced 110-ohm cable with XLR connectors — the same ones used in microphones — making it very practical and durable for studio use. shows and broadcast.

There is a consumer version with similar features, called S/PDIF, which generally uses coaxial (RCA) or optical (TOSLINK) cables.
