Wwise Help

Override parent

Determines whether the routing will be inherited from the parent or defined at the current level in the hierarchy. When this option is not selected, the output controls are unavailable.

If the object is a top-level object, this option is unavailable.

Default value: false

Output Bus

The Audio Bus in the Master-Mixer Hierarchy through which the object is routed.

This option is unavailable when the object is inheriting the output properties from the parent.

The Audio Bus can be unlinked to create a different routing path on a specific platform.

For more information, see To unlink the output routing for the current platform: .

Volume (to Output Bus)

The attenuation or amplitude of the signal routed to the audio output bus.

	Note
	The default slider range is from -96 to +12. You can go over those limits by entering the value directly, or by rolling the mouse while the focus is on the edit control.

	Tip
	When using the User-Defined Auxiliary Sends in a wet/dry mix scenario, the Output Bus Volume would be associated with the dry level, as opposed to the auxiliary send volume, which would relate to the wet level. Use an RTPC on Output Bus Volume and Auxiliary Send Volumes to control the balance from the game.

Default value: 0

Range: -200 to 200

Units: dB

Low-pass Filter (to Output Bus)

A Low-Pass Filter for the signal routed to the audio output bus.

A recursive filter that attenuates high frequencies based on the value specified.

The units for this filter represent the percentage of Low-Pass Filtering that has been applied, where 0 means no Low-Pass Filtering (signal unaffected) and 100 means maximal attenuation.

For more detail, see Wwise LPF and HPF Value Cutoff Frequencies .

Default value: 0

Range: 0 to 100

Units: %

High-pass Filter (to Output Bus)

A High-Pass Filter for the signal routed to the audio output bus.

A recursive filter that attenuates low frequencies based on the value specified.

The units for this filter represent the percentage of High-Pass Filtering that has been applied, where 0 means no High-Pass Filtering (signal unaffected) and 100 means maximal attenuation.

For more detail, see Wwise LPF and HPF Value Cutoff Frequencies .

Default value: 0

Range: 0 to 100

Units: %

Override parent

Determines whether the game-defined auxiliary sends usage will be inherited from the parent or defined at the current level in the hierarchy. When this option is not selected, the game-defined auxiliary controls are unavailable.

	Note
	If the object is a top-level object, this option is unavailable.

Default value: false

Use game-defined aux sends

Determines whether the object uses the game-defined auxiliary sends of the associated game object. A game-defined auxiliary send is a combination of an Auxiliary Bus and a send volume.

If enabled, the object is affected by the values coming from the game for the following functions:

Additionally, if the game has initialized Spatial Audio and sent Rooms and Portals data to Wwise, this option determines if the object sends to the Auxiliary Busses defined for Rooms and Portals based on the game object’s position.

Refer to Understanding Sends for further details this option.

Default value: false

Volume (Game-defined auxiliary sends)

Determines the attenuation on the game-defined auxiliary sends volumes set for the game object.

Use this volume to offset game-defined auxiliary send values.

	Note
	The default slider range is from -96 to +12. You can go over those limits by entering the value directly, or by rolling the mouse while the focus is on the edit control.

Default value: 0

Range: -200 to 200

Units: dB

Game-defined Auxiliary Sends LPF

A recursive filter that attenuates high frequencies based on the value specified.

The units for this filter represent the percentage of low-pass filtering that has been applied, where 0 means no low-pass filtering (signal unaffected) and 100 means maximal attenuation.

Default value: 0

Range: 0 to 100

Game-defined Auxiliary Sends HPF

A recursive filter that attenuates low frequencies based on the value specified.

The units for this filter represent the percentage of high-pass filtering that has been applied, where 0 means no high-pass filtering (signal unaffected) and 100 means maximal attenuation.

Default value: 0

Range: 0 to 100

Override parent

Determines whether the user-defined auxiliary sends usage will be inherited from the parent or defined at the current level in the hierarchy. When this option is not selected, the user-defined auxiliary controls are unavailable.

	Note
	If the object is a top-level object, this option is unavailable.

Default value: false

User Auxiliary Send

Determines the Auxiliary Bus this object is sending audio data to. Auxiliary sends can only target Auxiliary Busses.

To add an auxiliary send:

	Note
	Auxiliary Busses can be created anywhere in the Master-Mixer Hierarchy as children of an existing Bus or an existing Auxiliary Bus.

	Tip
	You can drag and drop an Auxiliary Bus object from the Project Explorer to the User-Defined Auxiliary Sends list to quickly add a send.

User-Defined Auxiliary Send Volume

Determine the attenuation of the signal sent to the Auxiliary Bus.

	Note
	The default slider range is from -96 to +12 dB. You can go over those limits by entering the value directly, or by rolling the mouse while the focus is on the edit control.

	Note
	This control is only active when an Auxiliary Bus is selected for a specific send entry.

Default value: 0

Range: -200 to 200

Units: dB

User Auxiliary Send LPF

The Low-Pass Filter applied on the signal that is sent to the Auxiliary Bus via one of the User Auxiliary Sends (User-Defined Auxiliary Send 0 - 3).

For more detail, see Wwise LPF and HPF Value Cutoff Frequencies .

Default value: 0

Range: 0 to 100

User Auxiliary Send HPF

The High-Pass Filter applied on the signal that is sent to the Auxiliary Bus via one of the User Auxiliary Sends (User-Defined Auxiliary Send 0 - 3).

For more detail, see Wwise LPF and HPF Value Cutoff Frequencies .

Default value: 0

Range: 0 to 100

Override parent

Determines whether the early reflections auxiliary sends usage will be inherited from the parent or defined at the current level in the hierarchy. When this option is not selected, the early reflections auxiliary controls are unavailable.

	Note
	If the object is a top-level object, this option is unavailable.

Default value: false

Early Reflections Auxiliary Send

Enables reflection processing in Wwise Spatial Audio and determines the Auxiliary Bus this object is sending to for early reflections processing.

Early reflections processing simulates the acoustic phenomenon of sound bouncing off of virtual surfaces defined by geometry in the game. Since the first few reflections convey the most spatial information to the listener, it is advantageous to process the early reflections separately (from the late reverb) and with more detail using the Reflect plug-in.

To render early reflections, the Reflect plugin must be assigned to an effect slot on the Auxiliary Bus assigned to an early reflections send.

If no send is specified, then Wwise Spatial Audio will not compute early reflections paths for the sound.

	Note
	It is also possible to assign a reflections Auxiliary Bus per Game Object via the Spatial Audio API. In the case that a reflections bus is assigned both via the API and to the sound in the authoring tool, the bus used for the sound is taken from the authoring tool.

	Note
	For reflections to be computed, the Wwise Spatial Audio library must be initialized and the game must send level geometry to Wwise Spatial Audio.

To add an auxiliary send:

	Note
	Auxiliary Busses can be created anywhere in the Master-Mixer Hierarchy as children of an existing Bus or an existing Auxiliary Bus.

	Tip
	You can drag and drop an Auxiliary Bus object from the Project Explorer to the User-Defined Auxiliary Sends list to quickly add a send.

Early Reflections Auxiliary Send Volume

Determine the attenuation of the signal sent to the reflections Auxiliary Bus. This control also effects the volume of the reflections aux send specified by the API.

	Note
	The default slider range is from -96 to +12 dB. You can go over those limits by entering the value directly, or by rolling the mouse while the focus is on the edit control.

Default value: 0

Range: -200 to 200
