Audio bus
In audio engineering, a bus is a signal path which can be used to combine individual audio signal paths together. It is used typically to group several individual audio tracks which can be then manipulated, as a group, like another track. This can be achieved by routing the signal physically by ways of switches and cable patches on a mixing console, or by manipulating software features on a digital audio workstation.
Using busses allow the engineer to work in a more efficient way and with better consistency, for instance to apply sound processing effects and adjust levels for several tracks at a time.
