A remix is an alternative version of a recorded song, made from an original version. Sometimes this term is also used for alterations of media or recreation other than song (film, literature, beverages etc.).

A remixer uses audio mixing to compose an alternate master recording of a song, adding or subtracting elements, or simply changing the equalization, dynamics, pitch, tempo, playing time, or almost any other aspect of the various musical components. Some remixes involve substantial changes to the arrangement of a recorded work, but many are harmonic, such as creating a "vocal up" version of a song that emphasizes the lead singer's voice. Contemporary remixes are often produced in a Digital Audio Workstation (DAW), which allow producers to reorganize tracks and apply various effects.

Songs are remixed for a variety of reasons:

Remixes should not be confused with edits, which usually involve shortening a final stereo master for marketing or broadcasting purposes. Another distinction should be made between a remix and a cover. A remix song recombines audio pieces from a recording to create an altered version of the song. A cover is a recording of a song that was previously recorded by someone else.
