Wwise Parametric EQ

To enhance your sound, you might want to create effects that will influence frequency components of the audio signal. Using the Wwise Parametric EQ plug-in, you can apply a variety of filters to shape the spectrum of your sound.

The Wwise Parametric EQ plug-in contains a series of properties that you can use to create the Effects for your audio environment. Many of these properties can also be mapped to Game Parameters using RTPCs. In addition you have the flexibility of working in three frequency bands where you can apply different properties to each band.

Wwise Parametric EQ Properties

Interface Element

Description

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.

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.

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 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.

Notes

Additional information about the Effect.

Metering

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.

Enable Band

Enables the set of filters that you can define. You have the option of enabling three different sets.

Default value: true

 

Curve

The type of curve for the filter effect:

  • 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.

Default value: High Shelf

Gain

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

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.

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

Frequency

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

Default value: 12000
Range: 20 to 20000
Units: Frequency

Quality Factor

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.

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

Default value: 1
Range: 0.5 to 100

 

Output Gain

The overall output level of the Wwise Parametric EQ Effect.

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

Process LFE

Determines whether the Effect is processed in the LFE channel or not. When selected, the Effect is processed in the LFE channel. When unselected, the LFE channel will be unaffected.

Default value: true
