audio-engineering

Audio engineering is a specific kind of engineering practice focused on sound capture, processing, and reproduction. A competent speaker calls it a branch of engineering.

The accepted definition carves audio engineering as the discipline of designing, capturing, processing, and reproducing sound, with parameters that are signal-processing operations: signal-chain design, mixing balance, dynamics processing. Remove signal processing and the discipline loses its processing, mixing, and dynamics tools — only passive acoustic layout remains, which the definition does not carry as its purpose — it stops operating as defined. Same accepted shape as music-information-retrieval →DEP→ signal-processing (ACCEPTED) and audio-feature →DEP→ signal-processing (ACCEPTED).

audio engineering practice removes signal and stops operating; engineering is about manipulating signal.

Its design parameters — gain, impedance matching, noise figure, phantom power — are defined by engineering requirements of audio signal handling, not by generic electronics alone.
