Aux Track

A track/channel in a DAW that functions similarly to an aux input on a hardware mixer — as a bus destination for routing signals, whether audio that was recorded on another track or tracks or that is being input from an external source. Audio entering the aux track does not get recorded in that aux track, rather, it passes through and can be processed using plug-ins (or external hardware, in some cases) and sent to another destination, such as the 2-bus output, another aux input, an audio track, or to a hardware output from the DAW’s audio interface.
