Audio Actions
While GameMaker Studio possesses its own audio functions which can be used in conjunction with VNgen, there are many times when you'll want to perform audio as actions in Quantum events. VNgen provides four categories of audio actions, all of which are specialized to behave in certain ways useful for creating engaging visual novels. These categories include sound effects, music, voice, and vox.
In this section we'll examine each, as well as each category's unique properties and how to modify sounds after they've started playing.
