A recording studio is a facility for sound recording and mixing. Ideally both the recording and monitoring spaces are specially designed by an acoustician to achieve optimum acoustic properties (acoustic isolation or diffusion or absorption of reflected sound that could otherwise interfere with the sound heard by the listener).
Recording studios may be used to record musicians, voice-over artists for advertisements or dialogue replacement in film, television or animation, foley, or to record their accompanying musical soundtracks. The typical recording studio consists of a room called the "studio" or "live room", where instrumentalists and vocalists perform; and the "control room", where sound engineers sometimes with producer(s) as well operate either professional audio mixing consoles or computers (post 1980s) with specialized software suites to manipulate and route the sound for analogue or digital recording. Often, there will be smaller rooms called "isolation booths" present to accommodate loud instruments such as drums or electric guitar, to keep these sounds from being audible to the microphones that are capturing the sounds from other instruments, or to provide "drier" rooms for recording vocals or quieter acoustic instruments.
Recording studios generally consist of three rooms: the studio itself, where the sound for the recording is created (often referred to as the "live room"), the control room, where the sound from the studio is recorded and manipulated, and the machine room, where noisier equipment that may interfere with the recording process is kept. Recording studios are carefully designed around the principles of room acoustics to create a set of spaces with the acoustical properties required for recording sound with precision and accuracy. This will consist of both room treatment (through the use of absorption and diffusion materials on the surfaces of the room, and also consideration of the physical dimensions of the room itself in order to make the room respond to sound in a desired way) and soundproofing (also to provide sonic isolation between the rooms) to prevent sound from leaving the property. A recording studio may include additional rooms, such as a vocal booth — a small room designed for voice recording, as well as one or more extra control rooms.
