Building simulations

The Soundcaster provides you with as much flexibility as you need to create a simulation for whatever purpose you have in mind. You can add whichever sounds, music, or motion objects you want to work with, and then change your mind as many times as you want. Building a simulation consists of the following steps:


You cannot work in the Soundcaster if there are no Soundcaster Sessions in the Sessions tab.

Creating Soundcaster sessions

Before you can use the Soundcaster, you need to create a Soundcaster session. You can create Soundcaster sessions in the following two places in Wwise:

  • Sessions tab of the Project Explorer.

  • Master control area of the Soundcaster.

To create a Soundcaster Session from the Project Explorer:

  1. In the Project Explorer, switch to the Sessions tab.

  2. Under the Soundcaster Sessions heading, do one of the following:

    • Select a Work Unit or Virtual Folder and then click the Soundcaster Session icon in the Project Explorer toolbar.

    • Right-click a Work Unit or Virtual Folder and click New Child > Soundcaster Session from the shortcut menu.

    A new Soundcaster session is added to the Virtual Folder or Work Unit.

  3. Replace the default name with one that best represents the Soundcaster session.

  4. Double-click the new Soundcaster session to open the session in the Soundcaster.


You can cut, copy, and paste a Soundcaster session in the Project Explorer using the standard Windows shortcuts. If you no longer need a Soundcaster session, you can delete it by pressing the Delete key.

To create a new Soundcaster session from the Soundcaster:

  1. In the Soundcaster, click the Soundcaster Session Selector button (>>) and select New from the list.

    The New Soundcaster Session dialog opens.

  2. Select the Work Unit into which you want to create a new Soundcaster session.

  3. In the Name field, replace the default name with one that best represents the Soundcaster session.

  4. Click OK.

    The Soundcaster session is created.

Adding objects or Events to the Soundcaster

When you add an object or Event to the Soundcaster, a module is created. A module represents the object or Event together with its properties and behaviors. It also has a series of controls that allow you to modify properties and play back sound, music, and motion objects.

When you are ready to mix and/or test some of the sounds, music, and/or motion that you have assembled, you can start adding the different modules to the Soundcaster. You can add any of the following to the Soundcaster as modules:

  • Busses

  • Actor-Mixers

  • Containers

  • Sounds

  • Music Containers

  • Music Segments

  • Events


If a Soundcaster session contains a module that relates to an object or Event that has been unloaded from the project, the controls will be unavailable and the title of the module will appear in yellow.

To add an object/event to the Soundcaster:

  1. Do one of the following:

    • Drag an object from the Audio tab of the Project Explorer into the Soundcaster.

    • Drag an Event from the Events tab of the Project Explorer into the Soundcaster.

    The blue module insertion indicator appears in the location where you have dragged the object/event. When you release the mouse button, the selected object/event is added to the Soundcaster as a module.

Re-ordering Soundcaster Modules

When you drag your objects or Events into the Soundcaster, you don't need to worry about their order because you can re-order them whenever you want to. Even though you can play back the modules in any order, you may want to arrange them in a particular order to recreate certain sequences or facilitate testing.

To change the order of Soundcaster modules:

  1. Drag the module that you want to move to the new location.

    The module is moved, and the module formerly in that position is shifted down in the Soundcaster.

Removing Modules from the Soundcaster

If you no longer need a module, or you are ready to create a new simulation, you can remove modules from the Soundcaster.

To remove modules from the Soundcaster:

  1. Do one of the following:

    • To remove one module, click the Close button in the title bar of the module.

    • To remove all modules, click Clear in the master control area.

    The module is removed from the Soundcaster.
