Good high speed analog tape has a brick wall

Studer B67, 15 ips, -3 dB @ 30 KHz for the first ten years of its
life.

OK, which is pretty close to 28 KHz, right? ;-)

And, there was the same-old, some-old gap-related brick wall just above
that, right?

I have to admit that I'm kinda overcome by all the complaining about digital
system brick wall filters, when the analog tape that some others seem to
want to deify had a pretty healthy built-in brick wall of its own. As I
recall, the group delay near the null due to gap length was fairly strong,
as well.

I am also comparing those kind of numbers to digital formats like 192/24
with ca. 93 KHz bandpass or 96/24 with ca. 45 KHz bandpass...

This is in no way intended to argue with the rest of your treatise.

OK. ;-)

But you do keep giving analog tape machine bandwidth slightly short
shrift. g

OK, I was thinking of typical numbers - those Studers were from near the top
of a relatively new pile, right?

I imagine that the last round of Otaris were pretty extended, as well.

Now, the TEAC 3340 I was given a while back...

Oh, oh! ;-)
