Problem Sample with Lame

Hi for all;

I encoded some CDs for the portable player of my brother.
I used Lame 3.96.1 --preset standard for this. The sound quality of the files are excellent. But; one particular song produced a strange and awful artifact; around first 2.5 seconds of the song.

This artifact sounds awful. I checked with -aps and -ap extreme with 3.90.3 and 3.96.1 with the same results. The rest of the songs sounds great. I think that is important to notify this. I uploaded the sample here:

Note: RIGHT CLICK and SAVE TARGET AS...

Download

This sample is only the first 5 seconds of the song.

Thanks a lot in advance and feedback

Can you hear the artifact only on the portable or on the pc ? I don't hear anything too weird let alone abx. -ap extreme should have reduced the artifact - if not I suspect some other problem.

The artifact is noticeable very easy with my headphones in my Stereo system. I obtained easy ABX without a wrong trial. I am sure that is not the PC

I can't hear any artifact using 3.96.1 --preset standard, but maybe my hearing is good enough.  Definitely nothing that grabs my attention by slapping me in the face.

I guess I should feel fortunate I can't hear it then.  I tried ABXing but only got 3/8 so entirely chance.

What kind of noise are you guys hearing?

A few thoughts: We should have been able to abx -api, but maybe cbr helps here because the vbr model is not giving enough bits ?

You might want to try 3.96.1 cbr 192k or even --preset fast standard ...

bad artifact again with --preset cbr 192  ... [Lame 3.96.1]

With --preset fast standard, the same bad thing.

with lame 3.90.3 in --alt-preset cbr 192 and --alt-preset fast standard the same bad thing again.

  My god!! this thing sounds awful !!!

I can ABX without a wrong trial too, in:

-aps, -ape, --preset cbr 192.

with -api is difficult to me too.

NOTE: tested with 3.96.1

just got 8/8 with 3.97 alpha 6 -V 2.  not a disturbing noise to my ears, barely noticable except when abxing.

i'm not all that used to ABX in general (my headphones are always off getting the headband fixed, you know...?), but even when i felt unsure i seemed to click the correct samples.

will try with insane (i hear extreme isn't really much of a cushion, and if it fail with standard it's likely it'll fail with extreme).

[edit]

i didn't stand a chance with --preset insane... will try extreme now

[edit 2]

extreme was just as easy as standard.  interesting.  must be a vbr thing.

Maybe... could someone explain it?

or maybe... a possible solution? (for example a command line to --preset standard or something similar?).

Thanks a lot for everyone for your replies

For the record, I still can't hearing but since all of you can my hearing just must suck

Since you guys can do it with the VBR modes but not 320k CBR then it must just be something with the VBR mode.  That or throwing 320 frames at everything masks the problem to the point you can't hear it.

It's pretty interesting to me even though I can't hear it and have failed trying to ABX it several times.
