To enhance your sound, you might want to create effects that influence the frequency components of the audio signal. Using the Parametric EQ plug-in, you can apply a variety of filters to shape the spectrum of your sound.
Parametric EQ 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.
Parametric EQ operates as an Object Processor, which means it is instantiated once per bus, as opposed to once for each Audio Object on each bus. This is done for performance reasons only and does not affect the result of the signal processing. Refer to Using Effects with Audio Objects for more information.

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. When you choose a color for an object, a palette icon appears on the selected square, as well as a yellow triangle in the lower-right corner, as shown. To inherit the parent object's color, select the square at the far left of the color selector. | ||||
Inclusion |
Determines whether the element is included in the SoundBanks when they are generated. When selected, the element is included. When unselected, the element is not included. To optimize your sound design for each platform, you might want to exclude certain elements on certain platforms. By default, this check box applies across all platforms. Use the Link indicator to the left of the check box to unlink the element. Then you can customize the state of the check box per platform. 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.
| ||||
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.
|
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:
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 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 |
