Yes, or differently and more complex.

You must understand that CD as technology harks back appx. 35+ Years. When CD as system was designed, it represented the ultimo ratio, the sine pari of technology. The 680MB of Data stored on a CD where so cutting edge in 1982, when big size hard drives were measured in MB and 2 Digit or less as well. Computers would take a decade to catch up on storage (also needs).

You might have read that from me. I might have mentioned an early Pioneer DVD Player that did that.

I have been doing that since the late 90's...

Not really. One merely must understand the variables and find "the knot of Gordias" in this, or what precisely produces the linkage between these variables. Then, like Alexander the Great, we may strike at the linkage and dissolve the knot.

Or we may instead not do it and commit the cardinal mistake, according to Vizzini, of getting involved in a land war in Asia.

BTW, simply ripping CD's to a computer SHOULD be trivial. I would like to submit that it often is a little less so than we would wish.

At 20 bits, you are on the verge of dynamic range covering fly-farts-at-20-feet to intolerable pain. Really, what more could we need?
