In this Instructable, I’ll demonstrate how I developed a workflow that can convert any audio file, of virtually any format, into a 3D model of a record, and how I optimized these records for playback on a real turntable. The 3D modeling in this project was far too complex for traditional drafting-style CAD techniques, so I wrote an program to do this conversion automatically. It works by importing raw audio data, performing some calculations to generate the geometry of a record, and eventually exporting this geometry straight to a 3D printable file format. . . .
This is *such* a rad project! Clearly not practical–it requires a big 3D printer with *really* high resolution in order to get a really low-resolution version of a single song–but I *love* the whopping oscillation artifact that the process introduces to the audio. *That* has some delicious sonic possibilities, in my humble.
Here’s a very brief interview/overview:
