It explains fade and stop cues to fade audio out over 5 seconds or stop it abruptly. Stop cues instantly cut all sound. Video cues play content instantly if loaded. Cue notes describe when each cue is needed in the performance. The document also provides an example of shortening and starting a sound cue earlier to make it more effective for the play.
