The document discusses audio techniques used in three different media productions: Doctor Who, The Stranger, and Tip the Waitress.
For Doctor Who, slow building piano music and various sound effects are used to set the scene and heighten drama. Galactic sounds suggest a future time period. Audio cuts out before dramatic scenes to enhance tension.
In The Stranger, narration with dark music is followed by sounds of a car crash. Walking and phone sounds further a tense situation.
For Tip the Waitress, a bell indicates someone entering a shop. Background noise suggests a busy environment. Chair screeching and water pouring sounds further immerse the audience.
