Lossy sourced: peaks over 16k?

[bludsucker]

Hi guys! I'm new over here.
Well, let's go down to business.
I downloaded a file which is (to me) obviously meant to frame.
Here you are caps from Tau Analyzer and CEP (full length and 2-sec span):

What do those peaks over 16K mean?
I am no MP3-lover so I'm not very sure if they should look like this.
They keep me intrigated.

Hoping a warm response!
:D

-----EDIT---
Oops!
Someone move this to Lossless, please!

I saw comparable results mostly on MD-recordings...especially both "MPEG" and "CDDA" in the same capture like in the screen on the top.

from what i understand, most of those built-in analyzers aren't very accurate...that said, definitely a lossy source, but probly MD [ATRAC compression]...doesn't look like mp3 to me

Thanks folks! Just what I suspected.
Gonna discard this crap right away. :mad:

from what i understand, most of those built-in analyzers aren't very accurate...
What's your suggestion then as for spectrum?

for stuff like this, i use Audacity [both FA and SA]...but i'm on a Mac

not sure what the best is on Windows OS
