Sounds - Truck Engine

The sound of the truck engine is very specific kind of the sounds.
Engine sound is very sensitive to be balanced between sound sources.

So there are a few rules for the engine sound:

• The each sound of the truck engine is in the separate sound bank.
• There are only three events and all must be implemented in the bank.
• It is not supported to combine events of different banks for the engine sound.

Engine Sound Events

• All events are at the folder "engine" in the events browser.
• This events should exist in the bank:
  engine/engine
  engine/exhaust
  engine/start_bad

Event "engine"

Event "engine" plays sound of the engine.
It have to be 3D event. The event should be routed to the "truck_engine" audio bus.

These event parameters must exist:

• engine/play
• engine/brake
• engine/load
• engine/play
• engine/rpm
• engine/turbo

Event "exhaust"

Event "exhaust" plays sound of the exhaust.
It have to be 3D event. The event should be routed to the "truck_exhaust" audio bus.

These event parameters must exist:

• exhaust/load
• exhaust/play
• exhaust/rpm

The purpose of the parameters is the same as for the "engine" event (see Event "engine").

Event "start_bad"

Event "start_bad" plays sound of unsuccessful starting of the engine.
It have to be 3D event. The event should be routed to the "truck_engine" audio bus.
The event is one-shot sound (without loop).
There are no other parameters for the event.
It is possible to use randomization of the assets supported by FMOD Studio.
