The MS HRTF plug-in is meant to be inserted on a bus, and converts the spatial audio data conveyed by that bus into a binaural (2-channel) signal for headphones.

It works on standard and ambisonic configurations, and transforms the output of the bus to two channels. In general, there is more spatial precision rendered in the HRTF binaural signal when there are more channels in the source bus.

However, the plug-in requires a sample frame size of 1,024. In the Wwise authoring tool, this can be set in the User Preferences' Samples Per Output Buffer list. In game, it is set using the AkInitSettings::uNumSamplesPerFrame() initialization setting. Additionally, the plug-in will only load in the authoring tool when running on an OS, such as Windows 10, that supports the Universal Windows Platform .

Interface Element



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.


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.


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.


Additional information about the Effect.

Effect Settings

Room Size Externalization is simulated by a room model, which can be tuned to one of the following values:
  • Small
  • Medium
  • Large
  • Outdoor
Outdoor is recommended when used with ambisonics or when the room model is already handled by the game.
