An audio engineer (also known as a sound engineer) is the person responsible for the technical aspects of a sound recording, sound system, or sound broadcast. They operate the equipment, (eg mixing console, microphone) and ensure that the material is of the highest quality available (high fidelity).
In a recording studio the audio engineer generally has very little input into the creative process, this is left up to the record producer. The audio engineer must interpret the direction of the producer and use appropriate techniques to achieve that goal.
Audio engineering has traditionally been a male dominated industry.
