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

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

Band

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

 

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.

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.

Default value: 0
Slider range: -24 to +24
Units: dB

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.

Freq.

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: 5.0
Slider range: 0.5 to 100

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

Output Gain

The overall output level of the Wwise Parametric EQ effect.

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.
