Master tape意思

"Master tape" is a term used in the recording industry to refer to the primary recording of a piece of music or audio that is considered the definitive version. It is the original recording from which all other copies or versions are made. The master tape is typically the highest quality recording of a song or album and is used for both the initial pressing of vinyl records, CDs, and other formats, as well as for subsequent reissues.

The master tape is created during the recording process and is usually a reel-to-reel tape, although in modern times it can also be a digital recording. It is carefully preserved and stored to prevent damage, as any damage to the master tape could affect the quality of all subsequent copies made from it.

In the context of vinyl records, the master tape is used to create a master disc (also known as a lacquer or master plate), which is then used to press vinyl records. The master disc is created by cutting a groove into the surface of a blank disc using a lathe, with the audio from the master tape being played back while the cutting is done. This process transfers the audio from the master tape onto the master disc, which is then used to make stampers that are used to press the vinyl records.

The master tape is also used to create digital audio files for CDs, streaming services, and other digital formats. In this case, the audio is transferred from the master tape to a digital format using a process called analog-to-digital conversion. The resulting digital files are then used to create the CD masters or to upload the music to digital platforms.

In summary, the master tape is the original and highest quality recording of a piece of music, from which all other versions and formats are derived. It is a crucial element in the preservation and distribution of recorded music.
