ABSTRACT
During the past 40 years, the processing and transmission of sound to film audiences have undergone a radical evolution. Filmmakers have a range of options for recording audio. The industry was dominated for many years by the Nagra, a portable audio tape recorder that was developed by Stefan Kudelski in Poland in 1951 that changed the way production sound was recorded in the field. In general, audiences are more critical of what they hear than what they see. The authors receive approximately 90 percent of their information through their eyes. Production sound consists of dialogue, the natural sounds associated with each scene, and any other sounds that might be of value during the postproduction process. Audiences want to hear what the actors have to say, and dialogue recorded on the set is usually the best representation of each scene.
