It sounds worse. It has a greasy XM-like sound to it.


Actually, it has CD-like sound. The difference is that analog FM has a
preemphasis curve, which is not used for HD.


David,

What does "CD-like" really mean?


It has audio that sounds like a CD, not FM analog, with the difference being
that anaalog FM is "colored" by the preemphasis curve.

Is it...
same noise level?
same frequency response?
same dynamic range?
same freedom from compression artifacts?
same distortion?
same skipping and pausing as I drive down a rough road?

The hype says like a CD, but never defines what it means.


A:B comparison of HD and a CD is nearly indistinguishable, but with Analog
FM it shows coloring.
