Imagine using a computer to synthesize music, but not being able to hear it as you built it. That's how it was in the 1960s - musicians only heard what they were composing in their mind's ear, until the project, usually riddled with mistakes, was finished and processed at a far-off lab.

This presented a challenge to the Princeton interdisciplinary team of engineer Ken Steiglitz and composer Godfrey Winham. They worked to build a device that would translate the ones and zeros generated by the IBM into analog sound, the only form of sound human beings can hear. The work they did together represented a watershed in the use of computers as a tool to create music.

Winham saw the potential of the computer as a musical device, and spent his best years building tools to make the giant machine more user-friendly to musicians. And Steiglitz was uniquely positioned to help Winham realize his vision.

This episode is the poignant story of their teamwork, as well as of the community of composers that created a wild batch of music on the IBM, music that has largely been long forgotten. But we’ve found it, and there are lots of clips of that music in this episode. We’ll take a detailed look at how humans are able to hear digital music. And we’ll explore the amazing story of Godfrey Winham, Princeton’s first recipient of a doctorate in music composition. Beyond his advances in music generation software, digital speech synthesis, and the development of reverb for art’s sake, he was a fascinating character.
