What is Routing?

Routing in audio refers to the process of directing an audio signal from one device, track, or channel to another within a recording or sound system. It determines how signals move through different pieces of equipment or software during recording, mixing, or playback.

In a digital audio workstation or mixing console, routing can be used to send audio from a track to effects processors, buses, auxiliary channels, or output channels. This allows engineers to apply processing, combine signals, or control how audio reaches speakers or recording devices.

Routing is an essential concept in audio production because it provides flexibility in how signals are managed. Proper routing helps organize complex sessions, apply shared processing, and control the overall structure of an audio system.
