Alesis Digital Audio Tape, commonly referred to as ADAT, is a magnetic tape format used for the recording of eight digital audio tracks onto the same S-VHS tape used by consumer VCRs, and the basis of a series of multitrack recorders by Alesis. Although originally a tape-based format, the term ADAT later also referred to hard disk recorders like the Alesis ADAT HD24. In 2004, recognizing the ADAT for "beginning a revolution of affordable recording tools," it was inducted into the first-ever TEC Awards TECnology Hall of Fame.
