Hello,

some off-topic notes:

The German "Linux-Magazin" (http://www.linux-magazin.de) features in
this months edition a title-story "MP3 Most Wanted!". The Article
describes (too shortly) the technique, encoders, (much too shortly)
software decoders and (too long) MP3-walkmen.

I like the part about encoders best. It first says that there are no
free encoders around and that the FhG-Encoder is much too expensive
(459,- deutschmarks for linux instead of 110,- dm for the
windows-version).

And then:

"As usual in free software, where there is a will there is a way.
Because layer 3 is part of the ISO standards, there is a
reference-implementation. it has many bugs and misses some features
of modern L3-encoders (Joint Stereo, VBR) and the encoded songs show
clearly audible errors at 128 kbit/s. [...]
The developers use a gap in judiction [excuse my translation] and
distribute patches against the iso-reference, not complete encoders. in
the meantime an active developer-scene has formed and there is a
project wich has made a promising second start: LAME!" [...]

LAME bases on the iso-implementation which it extends with many
important features such as VBR and Joint-Stereo. And above, the
quality is clearly better than that of the iso-code, because many bugs
were fixed and improvements included. Lame is the first free project
wich produces acceptable quality at 128 kbit/s! The development
proceeds rapidly and there is a new version pactically every weekend.
There is a mailinglist [ok, we might expect quite a few mor people in
here soon] so everybody might join developing. Main developer Mark
Taylor is very helpful and seems to invest a lot of work into this
project. There are many co-developers discussing on the mailinglist
witch have a very good knowlegde of digital signal-processing. This
all gives cause for hope.

I cannot at this time recommend LAME for production use without
restrictions, but this is only a question of time and maybe it is so
at the release of this article [i have to excuse for my translation
here!]. The latest version tested by me is v3.28, which gives
impressing results already. Only in some special songs there are some
artefacts by compression, but these are really tolerable. A definite
advantage of LAME: It�s fast! On my Alpha 533 SX164 it�s speed factor
is 1.35. On an overclocked Celeron 450 it is even faster. If you want
to encode something fast, you should cosider LAME. A further nice
feature is the graphical analsysis tool to compare input and output
and to analyse already encoded songs.

LAME is therefore the only serious free implementation of a
MP3-encoder. All others lack in quality, because they are only
speed-optimized variants of the ISO-reference (Blade, 8Hz, etc.)

[then some sentences about "encode" and commercial products by
FhG and Xing]

To some to an end, a hitlist of the linux-encoders by quality[...]:

1. FhG-IIS
2. LAME
3. Xing
4. encode
5. BladeEnc, 8Hz
