I yust cleaned my harddrive and by deleting old stuff I found an old file called "uzura3.zip". I opened it and found an mp3-encoder-source in Fortran. Because I had nothing else to do I searched the inet and found that this project is still active, downloaded a mp3-sample encoded by uzura3 (castanets) and IMHO it sounds quite good at 128kBit/s compared to encoders like Blade, Xing, dist10, shine, plugger... (ok, it´s not very difficult to sound better than these encoders). But anyway I downloaded the newest source to compile it. But what to do with f90-files? So I downloaded the Intel-Fortran-Compiler 6, but it couldn´t compile the code, I never had seen any Fortran-code before, so I have no idea what the problem is (IFL6 can compile: crc.f90; filter.f90; huffman.f90; inner_loop.f90; layer3.f90; mdct.f90; mpeg.f90 and psycho.f90. It cannot compile: uzura3main.f90; encode.f90; standard_f90.f90; windowsCVF.f90)
I just ran ifl with all files without any parameters. Is here any fortran-coder who can help me (please within the next 30 days, my license ends then) or anybody who has an win32-compile of uzura3?

Guess where I have the source/test-sample from. But like all mp3-encoders you cannot download the binary.

Yes, you can download only the source code at this site too.
Because FhG has patents of mp3 in Japan, like in other countries.

Here you can download MPEG-Encoders (dist10) as binary (MPEG Audio Tools). Now word that they are protected by law or can be used for testing-purpouse only.

Are the mp3-patents in the EU (Germany) also valid? Because MusePack also contains patented MPEG-algorithms and they have binaries on german servers.

They say so in their site.

I don't know about Musepack.

Uzura can be compiled by using Compaq Visual Fortran.

It is not a "very good" encoder, but features some interesting ideas, as the block switching algo...

When are those ideas going into LAME? .

I yust tested uzura3, it´s not a very good encoder, but better than many others so it´s a middle-class encoder. First I used default parameters, the result was not very good, then I used -mask -cuth. The result was much better, but the encoding was also much slower (0,58x realtime).
Is it similar to QDesign MP3? encspot guess the mp3 as QDesign, mp3guessenc don´t know ("maybe dist10 or other encoder"). The mp3s of uzura3 have padding, mixed/short/long blocks, joint-stereo (simple stereo / mid side). They don´t have any bit reservoir and intensity stereo.
When encoding VBR EncSpot guesses that the file is encoded by lame (old).
It doesn´t write xing-vbr-header and joint-stereo doesn´t work with vbr.

Just uploaded Uzura3 binary to RareWares. (Thanks, S_O and whoever compiled it)
