Bus

Definition

A signal routing path in a mixing console or DAW that combines multiple audio channels and routes them to a common destination — a group fader, an effects processor, or the master output.

In Simple Terms

A shared lane where multiple tracks get mixed together. Instead of adding reverb to every instrument separately, you send them all to the same bus and process them as a group.

In Practice

Eight individual drum tracks are routed to a single drum bus. The engineer applies EQ, compression, and saturation once on the bus instead of replicating those plugins eight times — saving CPU and ensuring that every drum gets the same processing character.
