XACT Runtime Parameter Controls

Some kinds of sounds inherently require run-time control to function correctly. For example, the sound of a car engine needs to have its volume and pitch adjusted according to gear and engine speed. Runtime parameter controls (RPCs) give the content creator control over how audio elements respond to changing conditions. With the Microsoft Cross-Platform Audio Creation Tool (XACT), the designer creates these controls and transfers them to the programmer for use in the title.

These controls are also known as sliders, because they mimic the function of slider controls on an audio mixing board.

To create and define an RPC, complete the following steps:

• Creating a Runtime Parameter Control
• Building a Runtime Parameter Control
• Associating Sounds with Runtime Parameter Controls
• Auditioning Sounds with Runtime Parameter Controls
• Adjusting the Cursor in the RPC Editor
• Deleting a Runtime Parameter Control
