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



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 Property Editor become unavailable.

Default value: false


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.


The type of effect.

Shared by (Used by)

A list of objects that currently subscribe to the selected ShareSet.

This field is called “Used by” when editing a custom instance of the Effect.

Opens a search field where standard alphanumeric entries filter out unmatching elements from the view. Learn more in Using Tables.

Click the Close icon to the left of the search icon to close the search field and remove the filter.

[Note] Note

The searches do not include elements in collapsed nodes of the List View, Query Editor, MIDI Keymap Editor, and Reference View.

Returns the Effect property settings to their default values.

This option is only available when editing a custom instance of the Effect.


Additional information about the Effect.

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.

[Note] Note

This property has no effect when the delay is used in an Auxiliary Bus. In this case, the dry level of the signal is defined by the object sending to the Auxiliary Bus. The effect will process a signal 100% wet.

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
