Hi, all.
I also tested differences of outputs from some decoders.
Output of mpg123 is almost identical to fraunhofer's, but
there are some mp3 files whose outputs have quite large
difference.
I made a mp3 file by adding a patch to lame so that lame
randomly selects block type, and output of mpg123 when decoding
this mp3 file has apparently large noise. The dist10 decoder
doesn't have this bug.
I investigated the mpg123 code. Perhaps, problem is in
dct12, dct64 and synth_1to1.
Now, I'm trying to make a patch that fixes this problem, but
this may take some days or more.
The mp3 file can be downloaded from:

And, I made a mp3 decoder plugin for winamp which is based on
current mpglib of mpg123. This can be downloaded from:
http://www.geocities.co.jp/Technopolis/9674/lametest/in_mpg123.zip
> WinAmp's EQ sucks bigtime. They all have the same frequency response.
Try my EQ plugin for winamp. It can be downloaded from DSP plugin
section of winamp.com.
