Mastering is the process of finalizing a recording and preparing it for the final medium on which it will be played back by consumers, radio stations, Disc Jockeys etc. Mastering provides the final polishing touches to the recordings and maximizes the volume of the songs so that they are competitive with other commercial recordings played back in clubs, Jukeboxes, radios and CDs. Mastering also provides continuity between tracks when they are placed on a compilation album so that there are no sudden overall volume changes between tracks.
