A studio is a place where an artist can work. Studios can be used for many things, such as photography, broadcasting, painting, making movies, television shows, cartoons, or music.
A movie studio is most often a company that makes movies. The place where movies are made may also be called a studio, or sometimes a "sound stage" because it also records the sound.
A television studio is where video production takes place. It usually contains cameras, microphones, speakers, and spotlights. It is similar to a movie studio.
A recording studio is used for recording music, speech, or other kinds of sound. They are typically divided into three areas: an "isolation room" that has soundproofing for playing instruments and to prevent echo, a "live room" for general recording, and a "control room" to store the recording equipment that DJ's use.
