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 about to put on the disk. And that requires a buffer, and that's very often digital. So it turns out there's precious little vinyl out there without a digital step being involved out there.

Not that it matters anyway, since vinyl is a pretty terrible technology, but still, it's kind of funny.
