The process of sound integration most often involves setting up connections to various game elements in the game engine. These hooks could be game state based, like calling a Wwise Event when the game starts, or based on actions in gameplay, like calling a Wwise Event on picking up an item. These connections are then directed to Events in Wwise, which will activate standard Event Actions like playing a sound, setting game syncs, and so on.
This certification will refer to Wwise Events as simply Events. Do not confuse Events with Unity Events.
Posting an Event means to post a request to play the Event Actions in a Wwise Event.
Calling an Event from Unity is done by scripting, but to simplify this process the Wwise Unity Integration provides you with various premade scripts, exposing high level controls that are easy to use in comparison to writing custom scripts.
