Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Best way to adjust global audio?

Hey folks,

I am currently working on a settings menu and was wondering what the best way to go about adjusting global settings.

I know you can adjust the volume of individual audio actors, but I was curious if there are any global audio settings that I can change from the HUD rather than monitoring all the individual audio by hand.

And hints would be very welcome!

There is one variable available to you on the AudioDevice called TransientMasterVolume, but be warned it resets back to 1.0 every area transition so it needs to be kept up to date.

A reasonable way to do this (probably, kind of thinking off the top of my head) would be to use the SoundClass and SoundMix systems. You could create a SoundMix object that affects your Master sound class and then manipulate the Volume Multiplier or something along those lines.

Awesome! I will look into it. Thanks for sharing! I definitely need to continue looking into the relationships of the different sound systems but this sounds like a good place to start (no pun intended)

To bring this thread up to date. UE4 (as of 4.7) still has no easy way to set a global volume.

However Rama's BP library has a Node that makes it very easy to set the volume for a SoundClass which makes this easier https://forums.unrealengine.com/showthread.php?3851-%2839%29-Rama-s-Extra-Blueprint-Nodes-for-You-as-a-Plugin-No-C-Required!&p=177568&viewfull=1#post177568

My solution has been to change the volume multiplier property inside the various sound classes. This would be pretty tedious for projects with a whole lot of sound classes, but mine only uses a couple. I'm posting this so it might help some people who also use this kind of sound class structure.

In the project settings you can also set the default sound class to make all further imported audio conform to the class you've made with a volume multiplier applied.
