High Definition Vinyl Is Happening
Quote:

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.

I’m trying to unpack this statement and a lot of it just doesn’t make sense to me. I get the part about using a laser process to make the stampers. That has real merit aside from the fact that there is a sampling / quantization process in the mix. This could be a really good thing.
Where my BS radar starts pinging is the statement about 30% more playing time, 30% more amplitude. Can’t have both, folks, and all this is possible with the exiting mastering techniques and cutting heads available today.
