The Alesis ADAT digital multi-track tape recorder is an iconic piece of early 1990s audio recording equipment. ADATs used consumer S-VHS videotape to record up to 8 tracks of digital audio. They were modular, meaning that each machine could be synced with up to 15 other ADAT machines. It was, therefore, possible, in theory, to create a home recording studio with the capacity to simultaneously record 128 tracks of audio, a process known as “mega-tracking”
In analog video, helical scanning and rotating recording/playback heads were the means to produce the larger bandwidth necessary to capture the analog video signal. Helical scanning was logically re-purposed for recording digital audio because it similarly requires substantial bandwidth. The original ADAT recorded at a sampling rate of 48 kHz/16 bits, later 20 bits.
The Alesis ADAT changed the entire recording industry, beginning a revolution of affordable recording tools. Overnight, the cost of digital studio recording plummeted from a sizeable $150,000 for the Sony PCM-3324 24-track to a relatively modest $12,000 for three ADATs at their original $3,995.’
Figures from the Audio Engineering Society suggest that twenty thousand were sold in its first year from October 1992 to November 1993 and 80,000 sold by 1998.’
