Arma 3: Sound: SoundControllers

Sound Controllers

Sound controllers deliver data from the engine in real time which makes them perfect to control volumes and frequencies of sounds. If you want to monitor sound controllers, you can use these functions:

• getAllSoundControllers - can only be used on vehicles.
• getSoundController - can only be used on vehicles.
• getSoundControllerResult - can only be used on vehicles.
• getAllEnvSoundControllers - can only be used on positions.
• getEnvSoundController - can only be used on positions.

Also look at this forum post for a video showcase and a great and simple to use example mission.
