Wwise Fundamentals

The Actor-Mixer Hierarchy groups and organizes all the sound and motion assets in your project. At the base of this hierarchy are all your individual sound and motion objects. You can define the properties and behaviors of these individual objects, but you can also take these objects and group them together so that you can define their properties and behaviors as a unit. To accommodate the complex nature of audio within a game, different types of objects can exist within the Wwise project hierarchy. Each object type has a set of properties, such as volume, pitch, and positioning, and a set of unique behaviors, such as random or sequence playback. By using different object types to group sounds within your project hierarchy, you can define specific playback behaviors of a group of sounds within the game. You can also define these properties and behaviors at different levels within the hierarchy to obtain different results.

Since motion is generally tied to audio in a game, Wwise uses the same principles and workflow for generating motion. This means that you can organize the motion assets for your game into hierarchies, and assign properties and behaviors in the same way as your audio assets.

You can use a combination of the following object types to group your assets and build a structure for your project:
