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.

The instrument is called Er-hu (like my teacher from Taiwan at the Institute of Musicology wrote it) or Erh-hu (like the New Grove Dictionary of Music & Musicians spells it). It is one of the oldest chinese instruments (i.e. more than 1,000 years old, as far as I remember) and - being a guitar player wink.gif - also one of my favorites from traditional Chinese music. The dictionary describes it as "a two-string bowed lute also know as nun-hu." It's played with a short bow tied behind the strings (so it won't get lost while conquering the continent on a horse) and placed on the lap of the player in front of him, also sometimes between the knees.

I was bored by harpsichord wink.gif


I did a mistake, as Hans-Jürgen said it. It's erhu, not ehru. I'm really sorry for this orthographical error.

For the Z affair discussed here, get Lame 3.90.3, it's solved (The improvements of Z have been included in the presets).
