IOW, there's nothing inherently wrong with the CD
medium, even though sometimes people abuse it and
create bad-sounding recordings.

Thanks for the comments. My non-technical
understanding was that cutting heads would round off
those square tops.

That would show up in the leading edge, not the
trailing edge.

Yes, indeed. I don't know what's supposed to happen at
the brick-walled peak.

Leading edge.

Is this discussion on the right track?:

I think this is the one I have criticized some parts,
agreed with others.

Yes, it is. I was interested in the illustration.

Especially the illustration to message #377599.

Not really. That relates to RIAA filtering which is
supposed to be symmetrical with filtering that was added
during recording. The two filters are supposed to cancel
out.

And the square wave reappears?

Ideally, yes.

The practical example of this is what happens when you use an inverse-RIAA
network (standard audio test bench component) to drive a RIAA phono preamp.
If the preamp is very accurate, the square waves that you put in, pretty
well come out of the UUT. Some rounding, and a little tilt in the real
world.

Thanks.
