Wwise Stereo Delay

The Wwise Stereo Delay plug-in can be used to create a variety of delay effects that can feedback to other channels in the Left-Right plane. It can be used to created expansive stereo effects (larger than life objects) or creative effects where the signal can bounce side to side (such as a ping-pong delay).

Wwise Stereo Delay Properties

The Wwise Stereo Delay plug-in contains a series of properties, many of which can be edited in real-time and can be mapped to specific Game Parameters using RTPCs.

Interface Element

Description

Inclusion

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.

Name

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.

Effect

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.

Notes

Additional information about the Effect.

Effect Settings

Left/Right Delay Parameters

Input

This parameter determines which channel(s) will be used to feed the corresponding (left or right) delay line.

Values:

  • Left/Right: The left or right channels will be used, respectively (default).

  • Center: The center channel (if present) will be used to feed the delay line.

  • Left/Right + Center: Left/Right signals will be downmixed with the center channel to feed the delay line.

  • None: The delay line input is silence.

Enable Feedback

This parameter determines whether the output of the delay line is fed back to the input of the same delay length.

Default Value: False

Feedback Gain

Gain applied to the feedback path before its re-injection into the same delay line input.

[Warning] Warning

Using high feedback gains can build up very high signal levels depending on the input signal content.

Default Value: -12
Range: -48 to 0
Units: dB

Enable Crossfeed L/R

This parameter determines whether the output of the delay line is fed back to the input of the delay length of the other channel's delay line. Left delay output can thus feed the right delay input and vice versa. This setting allows to create ping-pong type stereo-delays.

Default Value: False

Crossfeed L/R Gain

Gain applied to the feedback path before its re-injection into the other channel delay line input.

[Warning] Warning

Using high crossfeed gains can build up very high signal levels depending on the input signal content.

Default Value: -12
Range: -48 to 0
Units: dB

Filter Parameters

Type

Determines the type of filtering that can be applied to the wet signal. The following filters are available:

  • None to disable the filter.

  • Low Pass to provide a fixed sloped attenuation of high frequencies from a specified frequency. Below this point the signal is almost unaffected but higher frequencies are progressively more attenuated past the cutoff frequency point.

  • High Pass to provide a fixed slope attenuation of low frequencies from a specified frequency. Above this point the signal is almost unaffected while lower frequencies are progressively more attenuated below the cutoff frequency point.

  • Band Pass to reject all frequencies around the specified center frequency. The range of frequencies around the center is controlled by the Q.

  • Notch to provide a fixed attenuation of a specified frequency range with a varying width. The range of frequencies around the center is controlled by the Q.

  • Low Shelf to provide gain/attenuation for a specified range of low frequencies. This curve type is also known as Bass Tone Control.

  • High Shelf to provide gain /attenuation for a specified range of high frequencies. This curve type is also known as Treble Tone Control.

  • Peaking to provide amplification/attenuation of a specified frequency range with a varying width. The range of frequencies around the peak is controlled by the Q.

Gain

The amount of the amplification of the wet signal for the selected frequency band. Increasing this value “boosts” the audio signal. Decreasing this value “cuts” or attenuates the audio signal.

Default value: 0
Range: -24 to +24
Units: dB

[Note] Note

The Gain controls are not available when the Low Pass, High Pass, Notch, and Band Pass curves have been selected because these filter types have their passband normalized at 0 dB.

Frequency

The portion of the frequency spectrum that will be affected by the gain.

Range: 20 to 20,000
Units: Hz

Q

The area around the center frequency that will be affected by the change in gain. A low Q value means that the bandwidth range will be wide, and conversely a high Q value means that the bandwidth range will be narrow.

Default value: 1.0
Range: 0.1 to 20

This control is not available when the Low Pass, High Pass, Low Shelf, and High Shelf curves have been selected.

Output Levels

Dry

Gain applied to unprocessed signal.

Default value: 0
Range: -96 to 24
Units: dB

[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.

Wet

Gain applied to the delayed signal.

Default value: 0
Range: -96 to 24
Units: dB

F/R Balance

Front/rear extent of the stereo effect. For example a value of -100 will only have wet signal in the front channels. A value of 0 will have wet signal in both front and rear speakers. A value of 100 will have wet signal only in the rear channels.

Default value: -100
Range: -100 to 100
Units: None
