I found this problem when encoding with --preset medium for my portable. Strangely, --preset standard had the same problem, and --preset extreme too. Not insane, and not ... 128 kbps ! VBR seems to be guilty.
I tried with 3.90.2, 3.93.1 and 3.94a5. Takehiro is good, but the stable codecs have problems.
CBR is good. ABR is good. Funiest thing : --alt-preset fast standard is better than --alt-preset standard [3.90.2].

Instrument is a nice chinese violin, called ehru. The VBR encoding introduce raucous noise.

The file is > here <

Huh.. that's one of the worst artifacts I have heard with APS/APX, if not the worst! ohmy.gif
In 3.90.2/3.92/3.93.1 -Z makes it very much better, although I can still hear some slight rumbling.

This is one very good reason why imo --alt-preset extreme should have used -Z in Lame 3.93.1 and before.
