The user can change the sound in real-time by using playback (effect) parameters such as volume and filters.

The sound designer can configure the playback parameters using the authoring tool.
When the programmer plays back the sound using a Cue, it is played back using the playback parameters configured by the sound designer.
The programmer can change the playback parameters relative to those configured by the sound designer.
The programmer can set the playback parameters before or during playback.
Since the player handle can play back multiple sounds simultaneously, parameters can be changed simultaneously for all sounds, or independently for each sound.
