Digital Literacy Concepts: Sound

Information about concepts related to digital literacy.

Key Concepts for Sound

Diegetic and Non-Diegetic Sound - Diegetic 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 might be dialogue between characters, a radio playing music within the room the characters occupy, or audio occurring from character actions. Non-diegetic sound is heard only by the audience, and not by the characters on screen. Some examples of non-diegetic sound might be soundtrack music the characters do not hear, narrative voice-overs, or audience laughter in a sitcom.

Direct Sound - Direct sound refers to audio recorded at the time of filming. If a scene is captured using only direct sound, there are no added effects, soundtracks, or dubbing - everything captured occurs within the scene at the time of the recording.

Postsynchronization - Postsynchronization refers to the process of adding audio to the scene after it has been recorded. It is a staple of action and sci-fi films and used for martial arts, explosions, and lasers.

Microphone Polar Patterns

Cardioid - A cardioid microphone is a great all-purpose method of recording audio in your environment. The polar pattern of a cardioid mic will pick up a wide range of sound to the front and sides of the microphone. They are well suited for recording interviews and capturing ambient sound in an environment. The Zoom H1 and Zoom H4 are cardioid microphones available for checkout 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 the audio when recording for cinema 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.
