A sound recorder is a device used to capture audio. It can be as simple as a smartphone app or as complex as professional studio equipment. Sound recorders convert sound waves into electrical signals, which are then stored for playback or editing. They are commonly used in music production, film, and journalism. There are various types of sound recorders, including digital audio recorders, tape recorders, and field recorders. Each type serves different purposes, such as capturing live performances or recording interviews. The quality of the recording often depends on the microphone used and the settings chosen by the user.
