Because information is much easier to disseminate than it was in the 70s and 80s, there's tons of great information about how records are made down to the smallest detail. I noticed a resurgence of vinyl recordings and wondered why. My thinking went like this, forcing a cutting tool through lacquer while trying to maintain fidelity can't even be possible. The fact that purists think vinyl is so good, must indicate I'm wrong. My assumption was that digital media was going to be far superior simply due to the lack of mechanical inertia digital provides. You have quantization error turning analogue into digital and back to analogue again. My thinking was, sure, but this will be negligible and likely inaudible to most human beings.
I admit I was fascinated reading about how vinyl records were made. It is extremely complex and impressive. A cutting head needs to force a sharp stone (diamond) in 3 directions (left/right/up/down). The substrate needs to maintain the exact cut after it is done cutting and the cutting head needs to move so the groves don't get too close or too far away. Next, the signal can't have too much information in the left/right channel pair or the cutter won't be able to cut it or the playback needle will physically jump out of the groove during playback. It turns out this creation process is so complex, that only a professional lathe engineer can do this after a lot of experience. Something as simple as positioning the center hole of the disc is a nightmare and uses a trial and error approach. Not to mention all the equalization, volume limiting and frequency filtering that goes on so the signal will fit on vinyl.
A band who wants to go on vinyl needs to understand the limitations of the media. Actually, a band doesn't have the freedom to create any sound it wants. Vinyl tells you what you can put down. Ok, I glossed over all kinds of details about the media itself and the mastering process. The real kicker is that audiophiles think vinyl is analogue and better because of it. Guess what? There is no more analogue recording equipment in production. Everything is digital. Most lacquer lathes take a digital signal! So what you have is analogue to digital to analogue . What is the point of further transforming the signal so it fits on vinyl? The mastering process transforms the original source out of necessity to something that will work on a vinyl disc. My question is, how can this be better than the original digital source? My guess is the resurgence of vinyl is completely nostalgic.
