→Audio buses, routing and mixer
The definition of the sound buses and their routing is very important part of the Master Bank.
* Master Bus<Br>The master bus creates the final submix of all buses routed to it before outputting audio to the speaker channels.<br>All buses, return buses, and events not assigned to a group are routed into the master bus.* Bus<br>The bus is object which helps to collect specific sounds to groups and centaly control their volume or mute state.<br>Any sound event in the game should be assigned to the corresponding prepared audio bus.* Routing<br>Routing the events and buses by the mixer helps to control specific sounds in groups and applying effects (as a reverb) for the whole group of the sounds together.
Current table describes mixer principles in our Master Bank:

| master || || Example ''- none -'' || ExampleTarget for the central mixing of all other audio buses.<br>"Master" volume and mute state (from application settings) is applied to the bus.

|-
| .....<--- traffic outside || Example ''master'' || Example ''- none -'' || ExampleThe bus should not contents any sounds. It is only technically group to collect all sounds from the outer world.
|-
| .....<--- trailer exterior || Example ''outside'' || Example ''- none -'' || ExampleThe bus should not contents any sounds. It is only technically group to collect all exterior sounds.

|-
| .....<--- navigation unprocessed || Example ''outside'' || Example ''- none -'' || ExampleThe bus should not contents any sounds. It is only technically group to collect all exterior sounds which are not affected by sound processing (like reverb).
