It is not always clear what critics mean by "overproduction", but there are a minimum of a few common uses of the term:
All five of these meanings share the idea that a record producer or mastering engineer has made "unnecessary" additions or changes to a record in the production process and, in doing so, has decreased the quality or enjoyability of the music. There is little consensus among music critics or producers about when the use of an effect or production technique becomes excessive. For this reason, some producers consider the term unhelpful, confusing, and subjective.
The excessive use of dynamic range compression has been bemoaned by critics as part of the "loudness war". In August 2006, Bob Dylan criticized modern recording techniques, saying that modern records "have sound all over them" and that they sound like "static". Those responding to Dylan's comments seemed to assume that he was referring to the trend of increasingly compressed music.
In spite of the decreasing cost and increasing availability of professional or near-professional recording software and techniques, musicians and producers in some genres consciously set themselves against the idea of "overproduction" and attempt to make music with a rough or "lo-fi" sound.
