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:

> 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.
