Master recording
From Wikipedia, the free encyclopedia
A master recording is an original recording, from which copies may be made.
When recording on to magnetic tape, the original tape is known as the master tape.
A multitrack recording master tape or disk, on which productions are developed (or captured, in a live session) for later mixing, is known as the multitrack master, while the tape or disk holding a mix (mono, stereo, or Surround) is called a mixed master.
It is standard practice to make a copy of a master recording, known as a safety copy, in case the master is lost or damaged.
[edit] CD mastering
Compact Discs allow mastering in both audio and data formats, and also allow for remixing of the content.
A master disc may also be referred to as a "Gold Master". The derivation of this term is unclear. It predates CDs, so it is not related to the color of some CD-R backs or substrates. One possibility is that in the music recording industry, some original molds were plated with gold for preservation reasons.
