A properly designed production room is a laboratory designed to accurately capture, store, process, route, and reproduce audio information. Not every production room will facilitate every one of these processes. In the sound booth of a theatre, for instance, it may not be necessary to store or record a performance. In the type of production room we call a theatre, we will still capture information with a microphone and route that signal through a console. We may even process the signal from the microphone and add it to previously recorded sound cues, or sound effects, and then we will reproduce that combination of signals in the theatre for the audience (see Figure 3.1).
