Because so much emphasis is placed upon the visual image in television, audio is often overlooked. This aspect of a production is as important as the visual because aural elements convey just as much information. Music can add layers of emotion to a production. Sound effects can make a scene seem more realistic.
Operating the audio board during a production takes focus and talent. Knowing when to open or close channels, when to introduce music or bring it under a scene, and when to bring the entire board silent takes practice and skill.
