ADAT is a professional format, and while it has been replaced by the computer-based digital audio workstation[, it is still used by some in the recording industry. It is also still in use for scientific work, and to drive laser light shows. ADAT tapes are still available through some pro audio retailers with products from Maxell, EMTEC (formerly the tape division of BASF). HHB who used to supply them, now no longer have stock. ADAT HD24 Although it is a tape based format, the term ADAT now refers to its successor, the Alesis ADAT HD24, which features hard disk recording rather than the traditional tape-based ADAT. Many still use the ADAT as a simple I/O (in/out) for transfer of analog to digital signals.
"ADAT" is also currently used as an abbreviation for the ADAT Lightpipe protocol, which transfers 8 tracks in a single fiber optic cable. The ADAT cable standard is no longer strictly tied to ADAT tape machines, and is now utilized by analog-to-digital converters, input cards for digital audio workstations, effects machines, etc. One of the original benefits of utilizing ADAT versus S/PDIF or AES3 was that a single cable could carry up to eight channels of audio.
