An
audio engineer works on the
recording, manipulation, mixing, reproduction, and reinforcement of sound. Audio engineers work on the "...technical aspect of recording—the placing of
microphones, the turning of
pre-amp knobs, the setting of levels. The physical recording of any project is done by an engineer ... the nuts and bolts." Many audio engineers creatively use technologies to produce
sound for
film,
radio,
television,
music, electronic products and
computer games. Audio engineers also set up and operate
sound reinforcement systems for concert, corporate, theatre, sporting and other events.
