Dubbing (music)

One type of dubbing device combines two different storage media, such as an audio cassette deck that incorporates a Compact Disc recorder.

Another type of dubbing device is designed to rapidly produce many copies of a program.

This type of device can often perform the copying process at many times the standard playback speed.

Typical multiplexed dubbing decks of either analog (cassette) or digital (CD) programs can operate at 48 times the standard playback speed, thus producing complete copies of a program in sixty or ninety seconds.

In 1916, Victor developed an acoustical dubbing process to create new masters from pressings where damage had occurred to the originals.
