Microsoft DirectX 8.1 (Visual Basic) |
Applications can retrieve or set a 3-D listener object's parameters individually or in batches. To set individual values, your application can use the applicable DirectSound3DListener8 object method. However, applications often must set or retrieve all the values that describe the listener at once. An application can perform these batch parameter manipulations in a single call by using the DirectSound3DListener8.GetAllParameters and DirectSound3DListener8.SetAllParameters methods.
Parameter changes can also be made more efficiently by flagging them as deferred and then executing them all at once. For more information, see Deferred Settings.
