 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.SoundEdit first shipped in January 1988, as part of a hardware product called MacRecorder Sound System, by a company called Farallon Computing (which eventually became Netopia).
