DAT is the abbreviation of digital audio tape, which means "digital audio tape". Different from ordinary tapes, DAT is a new recording method developed for professional fields in 1980s, but its quality is much higher, and its sound quality is no less than or even higher than that of CD.

Because the DAC of professional DAT has exquisite workmanship and exquisite materials, the decoding effect and quality are very high. It is usually used as a master tape and then used to transcribe CDs, tapes and other devices. . . . . .

Although it has been out of the market for a long time, there are still quite a few music companies willing to use it as recording equipment or cheap decoders. . .
