  • Vinyl from digital files

    According to SciGo's, Super Factories, episode 7 vinyl records produced a European factory are sourced from digital files. That begs the question...why not just listen to digital files in the first place The companies name is GZ Media located in Prague, Czech Republic (11:06). If you listen carefully to scene with the record you can even her some wonderful static (11:09). Anyway according to the show the company is the biggest producer of vinyl records in the world making 24 million disks a year (11:53). They use a system called Direct Metal Mastering which according to Wiki, " Unlike conventional disk mastering, where the mechanical audio modulation is cut onto a lacquer-coated aluminum disc, DMM cuts straight into metal (copper)..."(12:28). The video of the DMM unit cutting the groove into the cooper plate is very cool. According to the show music recorded by artists in studios all over the world is loaded into the sound desk and information from the digital audio file is used to cut grooves in the master disk (12:32). I wonder at what resolution they receive the digital masters...
