It would be nice to have a bit more info.

Actually, according to tests on HydrogenAudio, most mp3 encoders really
aren't all that bad.  Even Xing, which people have complained about for
years, turns out to not be all that bad, in spite of missing VBR.

About the only one that is/was used that was known to be terrible was Blade.
The rest of the problems tended to be bugs etc. in specific versions.

By the time you get into the upper bit rates, they all start sounding near
transparent.  (By upper, I mean LAME's APS setting and comparable settings
for others.  Lame's APS averages around 190-200kbps with max of 256 and APE
averages around 224-256kbps with max of 320.)

This is partially due to LAME, Fhg, etc. being tuned for the higher bps more
carefully than what AAC and Vorbis have been.

But at the more limited rates (128k etc.), MP3 can't compete with Vorbis,
AAC, MPC, etc.

Sure, you can always find 'problem' samples that an encoder will have
trouble with, but all encoders will have problems with various samples.

Pretty pictures.... But considering audio quality is entirely subjective,
and is dependant upon how people hear, I'm not so sure that they are
relevant.

Sure, frequency range etc. can be important, but it's only one part of what
we hear and how we hear.
