The SoundDroid is an early digital audio workstation designed by a team of engineers led by James A. Moorer at Lucasfilm between 1980 and 1987. It was a hard-disk–based, nonlinear audio editor developed on the Audio Signal Processor (ASP), a large-scale digital signal processor for real–time, multichannel equalization and audio mixing. Only one prototype was ever built and it was never commercialized. Lucasfilm started putting together a computer division right after Star Wars as an in-house project to build a range of digital tools for filmmaking. The audio project that became SoundDroid was done in close collaboration with the post-production division, Sprocket Systems, and later spun out as part of a joint venture called The Droid Works. Complete with a trackball, touch-sensitive displays, moving faders, and a jog-shuttle wheel, the SoundDroid included programs for sound synthesis, digital reverberation, recording, editing and mixing. EditDroid and SoundDroid were the beginnings of the desktop tools digital revolution.
