Audio engineering involves working with sound in a technical sense to mix, record, and/or manage audible content. For instance, an audio engineer who specializes in music will piece together different instruments and vocals in a way that suits the client’s desires. Whether working in a studio or a live setting, audio engineering calls for an in-depth knowledge of both acoustics and the recording equipment being used. This knowledge extends both to the gear engineers personally use during production — mixers, digital audio workstations, rack-mount gear, and so on — as well as gear the performers use, such as microphones and amplifiers. This knowledge is a key component of audio engineering, as it allows for informed decisions on how best to capture and present sound while minimizing common problems like noise, feedback, and other undesired artifacts.
