Regardless of the film's length or budget, sound represents one of the most important elements to consider throughout all stages of production. Keeping aware of the different sources and types of sound at your disposal can help you use this element to great effect. Check the list below for some essential types of sound used in film.
Diegetic Sound: This type of sound is heard within the world of the film. The characters on screen can hear it as well as the audience. Some examples of diegetic sound include dialogue between characters, a radio playing music within the same room as the characters, and sounds caused by the characters' actions (ruffling newspaper, for instance, or hanging up a telephone).
Non-diegetic sound: This type of sound is heard only by the audience, and not by the characters on screen. Some examples of non-diegetic sound include soundtrack music the characters cannot hear, narrative voice-overs, and audience laughter in a sitcom.
Direct Sound: Direct sound refers to audio recorded at the time and place of filming. If a scene is captured using only direct sound, there are no added effects, soundtracks, or dubbing—the sound is captured on set and simultaneously with the scene.
Postsynchronization: This process involves adding audio and sound effects to the scene after recording. Examples include explosions, lasers, and combat sounds commonly heard in action and sci-fi/fantasy films.
A microphone's polar pattern determines the sensitivity with which it can pick up sounds from different directions. Whether on a live film set or recording music in a studio, choosing the right microphone for the situation can mean the difference between high- and low-quality audio.
Cardioid: Cardioid microphones are great all-purpose tools for recording audio in your environment. The polar pattern of a cardioid mic will pick up a wide range of sound from the front and sides of the microphone. Cardioid microphones are well suited for recording interviews and capturing ambient sound in an environment. The Zoom H1 and Zoom H4 cardioid microphones can be checked out at the MDC.
Supercardioid and Lobar: Supercardioid and lobar microphones pick up a limited range of sound in the direction they are pointed. They are often referred to as shotgun mics and have narrow polar patterns that pick up audio directly in front of them. They are well suited for isolating specific audio sources when recording for film and can be mounted on top of a camera or held on a boom pole. The Azden SGM-X and Sennheiser ME66 are supercardioid/lobar microphones available for checkout at the MDC.
