Sound design in film serves multiple purposes, including creating a realistic soundscape, enhancing the emotional impact of a scene, and providing information about the setting.

Dialogue is not a sound effect, but rather the spoken words of the characters in a film.

Foley is the process of recording and editing sound effects for a film, typically in a studio.

ADR (Automated Dialogue Replacement) is the process of recording dialogue that was not captured during filming, typically due to technical issues or poor sound quality.

Re-recording is not a technique used in sound design to create a sense of realism, but rather a process of mixing and editing the final soundtracks for a film.

The sound mix is the overall soundscape of a film, including dialogue, sound effects, music, and ambience.

Source music is not a common type of music used in film, but rather music that is heard by the characters in the film, such as music playing from a radio or a jukebox.

Incidental music is music that is used to create a specific mood or atmosphere in a film, and is typically non-diegetic, meaning that it is not heard by the characters in the film.

Gradually increasing volume is not a common technique used in sound design to create a sense of suspense, but rather a technique used to build tension and anticipation.
