An '''audio router''' is a device that transports audio signals from inputs to outputs.
== Inputs and Outputs == The number of inputs and outputs varies dramatically. The way routers are described is normally ''number of inputs by number of outputs'' e.g. 2×1, 256×256.
== Signals == The transported audio can be analog or digital. Digital audio usually is in the AES/EBU standard for broadcast use. Broadband routers can route more than one signal type e.g. analogue or more than one type of digital.
== Crosspoints == Because any of the inputs can be routed to any output, the internal arrangement of the router is arranged as a number of crosspoints which can be activated to pass the corresponding signal to the desired output.
