缨 A recorder, also known as a sound recorder, is an electronic device used to record audio. It can be used to capture a wide range of sounds from voices and musical instruments to environmental sounds. It works by converting sound into electrical signals which are then stored on a medium such as magnetic tape or digital memory. Recorders have been around since the late 19th century and have become increasingly sophisticated over time. Today they are used in many different contexts from recording music and podcasts to capturing wildlife sounds for scientific research.
