In sound recording and reproduction, audio mixing (or “mix down”) is the process which commences after all tracks are recorded and edited as individual parts. The mixing-process can consist of various processes but are not limited to: setting levels; setting equalization; using stereo panning and the addition of effects. The way the song is mixed has as much impact on the way it sounds as each of the individual parts that has been recorded. Dramatic impacts on how the song affects the listeners can be created by minor adjustments in the relationship among the various instruments within the song.
