What is a digital audio tape?
Digital audio tape (data) is a type of medium similar to the appearance as a cassette tape. The digital sound tape, which was introduced in 1987, was designed to replace the cassette tape as the primary media for recording and playback. Data is a digital medium, unlike cassettes that are analogue. Digital sound differs from analog sound in that instead of recording a continuous wavelength, digital sound records an analog wavelength of sound and converts it to a numeric equivalent for storage and playback.
In general, digital sound is easier to edit than an analog sound because it is out of time, leaving them out. While both analog and digital sound records the same sound, thanks to its storage mechanism it is possible to create a precise replica of digital recording. The analog sound often degrades over time because it is copied from one piece of media to another. Because data records in an uncompressed digital format can be made ofData to make accurate replicas. This is not the case with other digital media formats that use compression.
digital audio tape has never received the consumer market support because it was commercially competing with a compact disk (CD) and most of the main labels did not release data in data format. He has gained popularity in professional and homemade sound record, because it was the easiest way to create a main digital copy of many analog resources in the studio or live recordings. The standard of digital sound tape made four sampling modes: 32 kHz at 12 bits; and 32 kHz, 44.1 kHz or 48 kHz at 16 bits. Sample speed settings allowed to record more or less sound information on the same tape.
The tapes came from 15 minutes to 180 minutes. The digital sound tape was also used for computer backups. The format has been designed to be computer -specific, calledDigital data repository (DDS). While computer tapes and sound tape physically similar format, most DDS units are incompatible with sound tape data.
Digital audio tape in most recording environments fell out of kindness as the cost of storage on hard disk has reduced. Because hard drives allow digital recording with virtually unlimited lengths and quality, there is no longer an advantage for recording on digital sound tapes. Therefore, there are few companies that still produce data and tape players, and many older data recordings must be converted to newer formats or converted to storage hard drives.
