The document discusses the use of non-diegetic music and sound effects in the movie "Deadly in Love". It describes downloading a creepy instrumental track called "The Threat" from YouTube to serve as the main soundtrack. It also details adding a scream sound effect for a scene where the actress is attacked. The scream was recorded separately in GarageBand after muting the original diegetic scream. Care was taken to synchronize the added non-diegetic scream with the scene.
