How does it buffer audio? One thing I didn't realize for a long time is that it turns out that a lot of these machines have a digital stage. To cut a disk you need to pack the grooves as close as possible. But the spiral isn't fixed, it's adjusted dynamically. Quiet sections can be packed close together. That means that before cutting, the machine needs to know how much physical space it needs for the audio it's abou…
Do you need to, or only if you care about fitting the longest possible recording on the disk? How much shorter would an LP be if you used a fixed pitch?
I'd have to use my usb record player and rip some records and determine loudness vs length to get some baseline, though.
Then again, maybe most CD albums are two LPs, I only have a half dozen 2-LP albums, most older stuff is single LP.
Is that because albums have gotten longer, or louder? Both?
