A Sound Recorder records and reproduces any audible noise, including voice, using many different types of audio equipment. Besides equipment, learned techniques are also used to record, manipulate and enhance sound. Sound engineer, recording engineer, acoustical engineer and audio engineer are other names used to describe the Sound Recorder. While there are slight differences between these distinctions, they do essentially the same functions and as a Sound Recorder.

Audio engineers use equipment for the recording, mixing and reproduction of sound as well as being knowledgeable in the use of analog tape, digital multi-track recorders and understanding how to transfer analog sound to a digital format.

Using software and hardware specifically designed for audio recording, the Audio Engineer synchronizes and improves audio recording for a number of applications like movies, computer and console games and videos.
