lydsystem

Lydsystem is a term used to describe a comprehensive audio system architecture used to manage sound in music, theatre, broadcasting, and installation contexts. It encompasses hardware and software designed to capture, process, route, and reproduce sound across multiple devices and spaces.

A lydsystem typically includes inputs such as microphones or line-level sources; digital interfaces; a mixing or matrix console; signal processors like equalizers, dynamics, and effects; digital audio workstations or control software; amplifiers; speakers; and networked transport hardware.

In operation, it follows a layered approach: a physical layer handling cables and interfaces; a transport layer using audio-over-IP protocols to move signals between devices; a processing layer where DSP and plug-ins shape the sound; and a control layer providing user interfaces and automation.

Standards and interoperability vary by system, but many modern lydsystems support open or semi-open protocols such as AES67, Ravenna, and Dante for audio over IP, enabling devices from different vendors to interconnect. Implementation details and licensing can influence flexibility and cost.

Applications include live sound reinforcement, broadcast studios, recording and post-production facilities, and fixed installations in venues, houses of worship, and corporate spaces. The term emphasizes modularity and scalability, from compact setups to large distributed networks.
