Analog Illusion: Unraveling the Digital Veil in Contemporary Vinyl

I own a lot of records from the 1980s. The ones made from digital tape recorders often sound different from the ones made from analog tape - the digital recordings sound "crisp" whereas the analog ones sound "soft". Digital has much greater high-frequency headroom than analog.

Unfortunately, recording engineers often took advantage of the additional HF headroom to produce the 1980s "paint-peeler" recordings.

There were a couple attempts, including at least one commercially available, to make laser reading shellac and vinyl playback. Although being contact-free and so not damaging to archival material (good for museums, national music archives, etc.) the noise level requires massive amounts of post-transfer processing, with its own issues, to be usable. Generally built into the machine.

All good fortune,

It gets more "interesting" than that. The disc master is cut with a triangular stylus.
When played back we use a circular based stylus. Early on it was conical often with
a .007 radius. Later I used an elliiptical stylus with a .002x.007 geometry. Predistortion
was added to the cutting end to compensate for the "tracing distortion" from triangle
vs circular based stylus. What geometry was the compensation for? How do you fix
THAT? Now play with the laser. We're back to no wearout but the most difficult distortion
removal. Oh wait ! There IS a solution to ALL of this. Get a CD player. Problem solved.
Have you ever thought about the RC components in the RIAA network. Those also
NEVER match therefore EVERY analog playback sounds a little different. Can you tell?
Stop worrying about you dad's playback system. They don't make Oldsmobiles (your
DAD'S Oldsmobile) anymore either.

 
On further reflection, make it single-sided with RedBookCD on the other side, backwards compatible with automobile players. Maybe room for a hit single on top.

Peace and love to all,
