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. When I first started this project, I wasn't sure that the resolution of the Objet would be enough to reproduce audio, but I hoped that I might produce something recognizable by approximating the groove shape as accurately as possible with the tools I had. Despite all its precision, the Objet is still at least an order of magnitude or two away from the resolution of a real vinyl record. This printer has incredibly high resolution: 600dpi in the x and y axes and 16 microns in the z axis, some of the highest resolution possible with 3D printing at the moment. Like most 3D printers, the Objet creates an object by depositing material layer by layer until the final form is achieved. I printed these records on a UV-cured resin printer called the Objet Connex500. This project was my first experiment extending this idea beyond electronics. We can work off of relatively few cues (sometimes these even include contextual or visual cues) to piece together mangled or noisy audio and make sense of it this is how we are able to focus on one voice in crowded room or decipher a message sent over a cheap walkie talkie. We have evolution to thank for this: as we hear audio, some complicated processing goes on in our brains that makes us very good at ignoring noise and focusing on the important pieces of information coming through. The key is as long as you loosely approximate the overall shape of an audio signal, the output will sound reasonably recognizable. Through these projects, I've learned that audio is a very resilient medium, it can take a fair amount of abuse (in the form of distortion and compression) while still maintaining most of the integrity of the original sound. A great example is my Arduino Vocal Effects Box, where I used an Arduino to perform realtime pitch-bending on an incoming audio signal. This past year I've been posting a lot of audio projects, specifically, I've been experimenting with using relatively simple tools and techniques and very little memory to approximate and recreate digital audio signals. Also check out my laser cut records, made on wood, paper, and acrylic. Though the audio quality is low -the records have a sampling rate of 11kHz (a quarter of typical mp3 audio) and 5-6 bit resolution (less than one thousandth of typical 16 bit resolution)- the songs are still easily recognizable, watch the video above to see the process and hear what the records sound like. He says, "I cannot become egotistical about it.In order to explore the current limits of 3D printing technology, I've created a technique for converting digital audio files into 3D-printable, 33rpm records and printed a few functional prototypes that play on ordinary record players. As a messenger, Luciano always strives to be true and righteous as he delivers the word of Jah. He says "I've never stooped low and I'm not gonna bow to Babylon and no matter how much me angry bout certain tings, me nah come pon stage and express myself inna no negativeness". Luciano's most recent work to date is his album 'Jah Words' (released worldwide Apon the RAS record's label) which features such singles like the romantic 'Angel Heart' and the political 'Cry for Justice', the album also features his heavenly single with a distinctable thumping dancehall beat named 'Why Should I' with backup vocals by Shelene Thomas, Luciano even recorded a video for 'Why Should I' not widely know commercially but notably a dancehall classic like many.ĭoing good works are not confined to just music for Luciano, as he is a firm believer that he should be a positive role model. After recording several LPs for Burell he recorded a set for Island records before starting an independent career recording. It was later on that he changed his stage name to Luciano while often being referred to as "Jah Messenjah" and also at around that time collaborating with Fattis Burell's Xterminator label where he developed his conscious roots aspect. Luciano's music is influenced by Stevie Wonder, Frankie Paul and late reggae singer Dennis Brown.
