Audio post production
From Wikipedia, the free encyclopedia
Audio post production is the general term for all stages of production happening between the actual recording in a studio and the completion of a master recording. It involves sound editing, audio mixing, sound balancing and the addition of effects.
With today's increasing amount of music software and musicians creating electronic music in their homes, post production is often done by the musician himself. The process typically involves equalization, audio level compression, multi-band audio compression and limiting. This process somewhat overlaps but should not be mistaken by the term mastering, as post production is usually performed on a per-song basis, whereas mastering is aimed at preparing an entire list of songs to a specific media type.
One major aspect of audio post production is the use of ADR, or automatic dialogue replacement. 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.
