Wwise Help

Sound objects are the foundation upon which your Actor-Mixer Hierarchy is built. They represent the individual audio assets that you have created for your project. Each sound object contains a source, which defines the actual audio content that will be played in-game. In Wwise, there are two different types of sources: an audio source and a plug-in source.

Each sound object has a set of properties and behaviors that can be used to define how the object will sound and play in game. These properties and behaviors are located in the Property Editor. When you load an object in the Property Editor, the Contents Editor automatically displays a list of all the audio and plug-in sources found within the sound object. The Contents Editor also contains a series of controls that allow you to quickly edit the properties of a source without loading it into the Property Editor.

The descriptions for each of the sound object and audio source property and behavior options can be found in one of the following sections:

You may notice that certain property values in both the Property and Contents Editors have one or more indicators beside them. These indicators show whether the property value is linked to other platforms, whether the property value is associated with a Game Parameter using RTPCs, and whether a Randomizer has been applied on the property value.

The following tables describes the indicators that are used in each of these situations:

Indicator	Name	Description
	Link	A property value that is linked to the corresponding values of other active game platforms.
	Unlink	A unique property value that is not linked to the corresponding values of other active game platforms.
	Partial Unlink	The property value for the current platform is linked, but one or more corresponding values of other active platforms is unlinked.
	RTPC - On	A property value that is tied to an in-game parameter value using RTPCs. This means, for example, that the speed of a car in-game can be tied directly to the volume property in Wwise. As the speed of the car increases in-game, the volume in Wwise will change in real time.
	RTPC - Off	A property value is not tied to an in-game parameter value.
	Randomizer - On	A property value to which a Randomizer effect has been applied. A Randomizer enables you to define a range of possible values that can be used randomly each time the object is played.
	Randomizer - Off	A property value to which no Randomizer effect has been applied.

You can enable or disable the link and Randomizer features by right clicking on a particular property value. The RTPC settings are defined in the RTPC tab of the Property Editor.
