Mastering

Mastering, a form of audio post-production, is the art of preparing and transferring recorded audio from a source containing the final mix to a data storage device (the master); the source from which all copies will be produced (via methods such as pressing, duplication or replication). The format of choice these days is digital masters, although analog masters, such as audio tapes, are still being used by the manufacturing industry and a few engineers who specialize in analog mastering.
