Whenever a change has been made to a Trigger, Switch, etc., the item and all the folders above will be marked with an asterisk so you know where the changes have been made:


Control Types

Control TypeIconDescription
Triggers 

Image Modified

Triggers are containers that execute the audio middleware events connected to them. A Trigger might have any number of Events connected to it.
RTPCs
Parameters

Image Modified

RTPCs (Real-Time-Parameter-Controls) are used to seamlessly alter a parameter's value on which the Audio Middleware can receive and drive corresponding effects.

Switches

Image Modified

A Switch is a collection of States, each of which manipulate the connected parameters of a middleware in a certain way.

An example of a commonly used Switch would be that for character footsteps, that plays different footstep sounds depending on the surface (concrete, grass, etc.).

Environments

Image Modified

Environments are used to drive effects like reverbs and weapon reflections, in areas such as AreaBox, AreaShape, AreaSphere or AreaSolid that are found under the Area option of the Create Object tool.
Preloads

Image Modified

Preloads are requests to load audio specific files (such as SoundBanks in an FMOD Studio implementation) into memory. Any number of files can be grouped into a single Preload request.
Folders

Image Modified

Folders are only used for structuring the Audio System Controls in the ACE, and have no functionality associated with them.

Typing anything in this Search bar will show you only audio controls that contain the letters that you typed.

  • Stop - Indicates that the Fmod event/snapshot will be stopped when the trigger is executed.
  • Pause - Indicates that the Fmod event/snapshot will be paused when the trigger is executed.
  • Resume - Indicates that the Fmod event/snapshot will be resumed when the trigger is executed.

When connecting an Audio Trigger to an Fmod Snapshot, the following options are available:

OptionDescription
Action
  • Start - Indicates that the Fmod snapshot will start playing when the trigger is executed.
  • Stop - Indicates that the Fmod snapshot will be stopped when the trigger is executed.

When connecting a Audio System Controls Preload Request to an Fmod bank, the following options are available:

OptionDescription
<platform name>If enabled, the connected bank is loaded when the preload request is called on this platform.

Context Menu

When right clicking on a connection in the Properties panel, you get the following options:

OptionDescription
Remove ConnectionDisconnects this Middleware Control from the Audio Systems Control.
Select in Middleware DataSelects the middleware control in the Middleware Data panel.

Connecting Controls

To create new connections between audio system controls and audio middleware controls just drag the control from the Audio Middleware Controls panel into the Connections area. An audio middleware control can also be dragged directly into the Audio System Controls panel, this will create a new control with the name of the audio middleware control and automatically connect both of them.

Info

In the default color scheme Connected Controls are normally grey. However, if the connected control is not found in the audio middleware project it will be colored red.
