Wwise Delay

If you need to enhance your sound, you can use the delay plug-in to widen the sound and add echoes. The delay effect very simply delays an audio signal for a specified period of time. This delay sends the audio signal back to the input for the period of time specified and creates an echo effect. The delay time can range from several milliseconds to a second. When this delay time is long (more than 50 msec.), the delay produces an echo that can create really interesting effects. If you are using this effect for an instrument, for example, a single guitar riff, the result will fill out the sound of the guitar. If you use a short delay time, this can create a doubling effect to make it appear that there are more guitars. If feedback is added, the audio signal is repeated continuously and becomes quieter with every repetition. The same strategy can be used to efficiently create a crowd using a few dialogue clips.

Wwise Delay Properties

The Wwise Delay plug-in contains a series of properties that you can use to create the echo effects for your audio environment. Many of these properties can also be mapped to Game Parameters using RTPCs.

[Note] Note

The Wwise delay effect can also be used in an Auxiliary Bus.

Interface Element



The name of the Effect instance.

Effect instances are a group of effect property settings. They can be one of two types: custom instances or ShareSets. Custom instances can be used by only one object, whereas ShareSets can be shared across several objects.

Displays the object's color. Clicking the icon opens the color selector.

Select a color to apply it to the object.

[Note] Note

Selecting the square at the far left of the color selector causes the object to inherit its parent's color. When a color has been explicitly chosen for an object, it is displayed with the palette icon and a yellow triangle in the lower-right corner, as shown.


Determines whether the element is included or excluded. When selected, the element is included. When unselected, the element is not included. By default, this applies across all platforms. Use the Link indicator (to the left of the check box) to determine or to set platform-specific customizations.

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

Default value: true

Indicates the number of elements in your project that contain direct references to the object. The icon is displayed in orange when references to the object exist, and in gray when no references exist.

Selecting the button opens the Reference View with the object's name in the References to: field.


Additional information about the Effect.


Indicates the name of the object currently being metered.

Allows you to browse for other objects to meter.
[Note] Note

The metering interface elements only appear in the Effect Editor for Effects that include VU meters.

Sets the display of the Effect Editor's selected tabs. By default, there is one panel displaying only one selected tab. You can, however, click a splitter button to split the panel into two, either side by side or one on top of the other, for two different tabs. The currently selected option is highlighted with a background color.

[Note] Note

You cannot display the same tab in both panels. If you select the tab that is currently displayed in the other panel, then the other panel will automatically display another tab.

Delay time

The amount of time of the delay. A short delay time or echo creates the effect of doubling. A longer time creates an echo.

Default value: 0.5
Range: 0.001 to 1
Units: s

Enable Feedback

Determines whether feedback will be used in the delay effect.

Default value: true


The amount of delayed signal that will be sent back to the input. The volume of the repeated signal becomes quieter with each repetition.

A high percentage of feedback can create a howling effect as the delayed sound is heard repeatedly.

Default value: 15
Range: 0 to 100
Units: %

Wet/Dry Mix

The amount of the processed signal that will be output.

A value of 0 means you have a completely dry signal. A value of 100 means you have a completely wet delayed signal.

Default value: 25
Range: 0 to 100
Units: %

Output Level

The overall output level of the delay effect.

Default value: 0
Range: -96.3 to 0
Units: dB

Process LFE

Determines whether the Effect is processed in the LFE channel or not. When selected, the Effect is always processed in the LFE channel. When unselected, either of the following occurs:

There will be silence in the LFE channel, if the Effect is used in an Auxiliary Bus.

The LFE channel will be unaffected, if the Effect is applied as an inserted effect.

Default value: true
