An audio engineer helps to produce a recording or a live performance, balancing and adjusting sound sources using equalization, dynamics processing and audio effects, mixing, reproduction, and reinforcement of sound. Audio engineers work on the "technical aspect of recording—the placing of microphones, pre-amp knobs, the setting of levels. The physical recording of any project is done by an engineer…"

Equalization, or simply EQ, in sound recording and reproduction is the process of adjusting the volume of different frequency bands within an audio signal. The circuit or equipment used to achieve this is called an equalizer.
A stereo graphic equalizer. For the left and right bands of the sound content, there are a series of vertical faders, which can be used to boost or cut specific frequency ranges. This equalizer is set to a smiley face curve, in which the mid-range sound frequencies are cut.
Equalizers are also made in compact pedal-style effect units for use by electric guitarists. This pedal is a parametric equalizer.
