This wooden record lets you listen to Radiohead the low-tech way
Artist Amanda Ghassaei managed to take a digital copy of a song and laser etch it into a slab of maple, thereby creating a wooden record. By etching Radiohead's "Idioteque", and the Velvet Underground's "Sunday Morning" into the wood using Python, a PDF, and a lot of math, Ghassaei may have unintentionally created sustainable music.
But what kind of quality are we talking about? Ghassaei spills the beans in her Instructables guide and says that the record "has a bit depth between 4-5 (typical mp3 audio is 16 bit) and a sampling rate up to about 4.5kHz (mp3 is 44.1kHz)."
If that makes sense to you, then this project may be right up your alley. I, on the other hand, may just stick to picking up digital albums on iTunes and vinyl on Amazon.
While the project files look complicated and full of mathematical equations, Ghassaei has put together a ten-step guide to convert your music from WAV files into a format you can use to turn your digital music into analog wooden files, thankfully.
It may not be efficient, or audibly pleasing enough to add these records to your music collection, but it would certainly make a great conversation starter on the shelf next to your turntable.
