Audio post production

Audio post production is the creation and manipulation of audio that is synchronized with moving picture. This includes, but is often distinguished from Production Audio, which is the audio recorded as filming/shooting occurs. Most other aspects of audio for moving picture occur during the Post Production phase, or everything done after filming/shooting. This also may include Sound Design or the create of Sound effects, which can occur during Pre Production, Production, or Post Production. This applies to TV, cinema, and commercials. One major aspect of audio post production is the use of automatic dialogue replacement (ADR).
Sometimes the original, or production audio, lacks in performance or quality, and the actor or actors are brought into a sound studio to record some or all of their dialogue from the project. Other elements such as Foley, music, and voiceover, are also added during post production.[1]

The term ' Audio post production ' is sometimes used to refer to parts of the process of producing music (i.e. Mixing or Mastering), although the standard nomenclature of the Audio Engineering Community refers to these generally as Music Production and any audio produced for moving picture as Audio Post Production.

Reworking and enhancing voice-based media is prevalent in the form of noise reduction and volume normalization. With the emergence of podcasts, audio post production with a focus on vocals has become more common. Sound recording devices with different characteristics and capabilities such as dynamic range has led to increased demand for consistent sound. With many techniques being adjusted specifically for vocal audio, the field is becoming more understood as unique to music production. The automation of post production vocals is demonstrated by tools like Audamate[2] which uses a combination of machine learning, analysis and reactive mixing.
