Simple Explanation

A professional digital audio format that uses XLR cables to send sound between gear, like mixers and recorders.

Concise Technical Definition

A digital audio transfer standard created by the AES (Audio Engineering Society) and EBU (European Broadcast Union), typically using a 110-ohm balanced XLR cable. It’s a common alternative to S/PDIF.

Layman-Friendly Analogy

Think of it like a professional “digital audio handshake” using microphone-style cables to send clear signals between devices.

Industry Usage Summary

Widely used in professional studios and broadcast environments, AES/EBU transmits high-quality digital audio over balanced XLR connections. It's preferred for long cable runs and robust signal integrity compared to unbalanced formats like S/PDIF.

Engineering Shortcut

AES/EBU = pro digital audio over balanced 110Ω XLR; S/PDIF’s big brother.

Full Technical Explanation

AES/EBU (officially AES3) is a digital audio interface standard developed by the Audio Engineering Society (AES) and European Broadcast Union (EBU). It transmits two channels of digital audio over a 110-ohm balanced line, most commonly using XLR connectors. AES/EBU is designed for professional environments and offers greater signal integrity, lower susceptibility to noise, and support for long cable runs. It supports a wide range of sample rates and resolutions and is frequently used in digital mixers, recorders, interfaces, and broadcast gear as a robust, industry-standard alternative to S/PDIF.
