Hello to all!
Implementing sound into Unreal Engine 4 is a challenge on its own if you are new to sound implementation. This is where looking at the online manual really helps you out! Mixing audio within the engine is something you need to learn off the bat to make sure you have balanced the audio correctly so you don't get any conflicting sounds within the engine which is very easily done. In the Unreal Engine 4 manual they have stated a baseline on how you can mix all different elements of audio within the engine itself! The audio in unreal is measured in volumes so the following numbers are what volume you should have your sounds within the game engine:
Dialogue - 1.4
Music - 0.75
Weapons - 1.1
Ambience - 0.5
To reiterate this is for mixing within the game engine. If the sound you are working with in these parameters you think are too loud or too quiet you can play with the settings in the engine to make them louder or quieter. But to stick with baseline measurements for the sake of sticking to the manual, edit your sounds in your main digital audio workspace such as reaper and pro tools.
No matter what the Audio System Overview (or what I call the Unreal Engine 4 manual) is there to help you beginners get off your feet. It is simple to follow as you are taught the basics of audio implementation there.
