How do I modify the volume of all audio events and ambient sounds?

Question

Hello Audiokinetic,

I would like to add a "Global Volume" setting for my UE4 game that modifies the volume of all audio events and ambient sounds.

It seems that the default UE4 audio engine supports this, but the Wwise UE4 audio engine does not support this. How do I achieve this?

Hi Johann,

Modifying volume for a group of sounds or all sounds in the game is usually done on audio busses (in the Master-Mixer Hierarchy). If you want to expose a slider in the game's menu to modify the master volume, I'd suggest you attach an RTPC to the 'Bus Volume' of the Master Audio Bus.

Okay, thanks for answering my question.

Hello,
I'm trying to achieve the same (assigning values to the sliders in the game's menu). I've created and assigned the RTPC that controls bus volume to the master audio bus (and sub-busses). What coding information should I pass to the programmer in order for him to integrate this functionality? Do I need to create an event for that? BTW we're working on a Wwise/Unity project. Thanks!
