Hello Everyone,
I don't know the value of this, because I cannot do anything myself or
don't have any real concrete constructive suggestions, so I'm left
only to report I've found a track that sounds not as it should imho.
I made a short clip out of it and you can find it (no permanent link)
http://www.r3mix.net/kingdom.zip 1.330.218B
It's a seven second clip from manowar - kings of metal - kingdom come.
Don't mind the genre, but it's really sensitive encoding material
imho.
LAME382/Dmitry -V1 -mj -h -b128 gives:

I believe this is a severe case of:
chirps: high-frequency distortions added to the audio, will sound like short chirps,
whistles, sometimes can shwoosh up like a high-pitched glissando (slide).
as David McIntyre would say. I would say: the sharp high-squeeling noise
that makes the back of your skull/neck hurt and just about the single
most painful artifact on the block.
Listen to the "K" from "Kingdom" and the (cymbals?).
S/JS makes no difference @256 and I don't really hear a difference, or
let's say I can enjoy the clip 100% at 256kbit/s. It might have a
sharper feeling to it, but nothing to be disturbed about.
I know a 7 sec clip is really short thing to listen to, but the
?cymbals go on for 4 minutes, and 4 minutes of the same artifacts.
I know you're all _very_ hard working and motivated people, and I'm
just new here. The last thing I want to do is complain and whine and
demotivate you without offering the solution. If that is the case,
please disregard my remarks.
I just got my new set of headphones, so it might be that -V1 just
isn't the setting for me, and I should go for 256 anyways, but most
songs I listened to sounded ok with this setting on the new gear, so
maybe a tweak is in order :)
btw: I also did a quick meaningless freq analysis, and the 256 is
right up there until 20kHz, and the VBR is off the scale since exactly
16kHz. What defines this magical 16kHz? (or is this just a big
coincidence?)
Thanks for LAME
