The Meter plug-in Effect measures the level of a signal without modifying it, and optionally outputs this level as a Game Parameter. The dynamics as well as the range of the output value can be adjusted. It is most useful for achieving side-chaining, where the measured level of a bus drives the volume of another bus through RTPC.

Meter properties

Interface Element



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.


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.


Additional information about the Effect.


Indicates the name of the object currently being metered.

Allows you to browse for other objects to meter.


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.


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.


The metering mode. This plug-in can be set to track either peak values or RMS.

  • Peak: Sets the meter to be in Peak mode, which tends to be more reactive to transients.

  • RMS: Sets the meter to be in RMS mode, which might be better suited for voice work.

Default value: Peak


  • Global: Sets the meter to work on all input into the applicable Wwise audio element (be it a bus, container, Music Segment, or anything else), treating multiple game object instances of the element as a collective single game object.

  • Game Object: Sets the meter to apply to input into each game object instance.

Default value: Global



The time it takes for the output value to rise by 10 decibels, when the monitored level is above the current output value.

Default value: 0.0

Range: 0 to 10

Units: s

Infinite Hold

When enabled, the output value is held indefinitely at the highest level monitored after the option was enabled. In other words, the output value can increase but never decrease.

While this option is enabled, the Hold property value has no effect.

Default value: false


The time it takes for the output value to start falling from the moment the monitored level goes below the current output value.

Note, this property has no effect while Infinite Hold is enabled.

Default value: 0

Range: 0 to 10

Units: s


The time it takes for the output value to fall by 10 decibels, when the monitored level is below the current output value.

Default value: 0.1

Range: 0 to 10

Units: s

Output Game Parameter

When set, the output value will be sent to this Game Parameter based on the playing instance's Scope, be it a specific Game Object or globally.


Make sure that the range of the selected Game Parameter contains the output value range. For more information on setting the Game Parameter range, refer to Property Editor: Game Parameter.


The minimum output value.

Default value: -48

Range: -96.3 to 0


The maximum output value.

Default value: 0

Range: -96.3 to 12

Apply Downstream Volume

When enabled, the meter will display volume gains applied at a higher level. For example, if the volume of the Master Audio Bus is increased by 10 and that of a child Audio Bus is decreased by 15, then all its children will inherit the sum total gain of -5. Although the gain is always audible, unless this option is enabled the meter will normally not show it.

Default value: false

(VU Meters)

A pair of meters that display the input level of the audio signal, and output value of the Game Parameter.

To enable the VU meters, you must click the Start Capture button in the Wwise toolbar.

The VU meters only work when the Effect has been applied to a bus in the Master-Mixer Hierarchy. In the case of a ShareSet, the bus must be selected in the 'Shared by' list of the Effect Editor.
