Preemphasis/deemphasis curves (plural) that are 100% complimentary. An
analog noise reduction solution 80 or so years old, that works quite well.

But the curve changes the noise level, which can not be ignored in analog.
It changes the color overall.

"CD like" is a bull**** term with no meaning. They also like to throw
"digital quality" around. CT aac+ SBR sounds bad. It causes listener
fatigue.

The test is to have people who are not technical listen to a CD, HD and
analog FM with the same source. HD and CD are perceived as being the same,
while analog FM audio is not.
