The HD vinyl process involves converting audio digitally to a 3D topographic map. Lasers are then used to inscribe the map onto the “stamper,” the part that stamps the grooves into the vinyl. According to Loibl, these methods allow for records to be made more precisely and with less loss of audio information. The results, he said, are vinyl LPs that can have up to 30 percent more playing time, 30 percent more amplitude, and overall more faithful sound reproduction. The technique would also avoid the chemicals that play a role in traditional vinyl manufacturing. Plus, the new-school HD vinyl LPs would still play on ordinary record players.
