Contents Editor: Blend Container

This Contents Editor gives you quick access to the properties associated with the objects within the Blend Container. It is divided into two separate panes:

  • Object list pane that lists the objects in the Blend Container.

  • Blend Track pane that allows you to assign the objects to the various blend tracks.

Interface Element


Click the Configure Columns shortcut (right-click) option from the column header band.

The Object Property Settings opens. Specify which columns to display and their order.


The name of the object.


Determines whether the element is included in the SoundBanks when they are generated. When selected, the element is included. When unselected, the element is not included.

To optimize your sound design for each platform, you might want to exclude certain elements on certain platforms. By default, this check box applies across all platforms. Use the Link indicator to the left of the check box to unlink the element. Then you can customize the state of the check box per platform.

When this option is unselected, the property and behavior options in the editor become unavailable.

Default value: true

Voice Volume

The attenuation (level or amplitude) applied on the current object before it is routed to a bus or sent to an Auxiliary Bus. Refer to Understanding the voice pipeline for more information about volumes.

Default value: 0
Range: -400 to 400
Units: dB


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.

Voice Pitch

The playback speed of an audio structure, where:

  • Pitch 0 = Normal speed.

  • Pitch 1,200 = 2 x speed.

  • Pitch 2,400 = 4 x speed.

  • Pitch -1,200 = 0.5 speed

  • Pitch -2,400 = 0.25 speed


1,200 cents is equivalent to one octave.

Default value: 0

Range: -2400 to 2400

Units: Cents

Voice Low-pass Filter

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: %


Any additional information about the object properties.

Blend Tracks

The list of objects within the Blend Container that have been assigned to a particular blend track.

Each blend track is divided by a title bar that displays its name. Dragging and dropping containers onto that name adds it to the blend track.

You can expand and collapse the blend track groups by clicking the arrow on the title bar.
