The Macintosh had no built-in sound input, so the MacRecorder audio digitizer was invented for this purpose in 1985 by Michael Lamoureux, a mathematics student at the University of California, Berkeley. The MacRecorder hardware and software was publicly released through the Berkeley Macintosh Users Group as a kit in late 1985.
