       * based on libvorbis 1.2.0
       * The noise control of the Impulse block was expanded. 
         This is effective with the outstanding sample of the pre-echo.
       * The pre-echo reduction code came to work at a lower bit rate.
       * Noise Normalization was reviewed. As a result, the bug is revised.
       * The detailed tuning was done again.

       # The action of noise normalization has been improved.  This has an effect in the sound roughness and tremor problem etc. in the low bitrate.
       # The threshold of a stereo mode change was calculated dynamically.  Some of problems which originate in channel coupling by this will improve. 
       # Noise control of an impulse block was changed (quality 0-10 / 32-48kHz). And pre-echo decreased slightly. 
       # Tuning of each part was redone according to above-mentioned changed part and additional part.

       # Reexamination of a low bit rate region, the addition of the code accompanying it, and tuning. Influence has this change below quality3.  Probably, in the especially low bit rate, it will be effective.

       # An addition and change of the code of a channel coupling processing portion. Thereby, disorder of the sound energy on hearing becomes small.  And a part of additional code of beta3 which is not required has already been deleted now.
       # Tuning of Masking relation and Noise Normalization. These mainly influence balance and the quantity of distortion which can be heard.
       # The bit allocation by the low bit rate was devised. This is generally effective.
       # Bug fix of beta3

      < <Since beta2 was adopted as official 1.1, beta3 uses 1.1 as a base. >>
      #  bitrate management mode operates normally now. It not only became new, it offers new rate control. (changed part of Vorbis 1.1 by Monty) 
      # Pre-echo was decreased in the mode of q0-q10. 
      # Since some codes of beta2 were not working normally, correction and re-tuning were carried out. 
      # In the mode below q3, the problem to which a part of sound becomes unstable is improved. (e.g. piano/strings)
      # Distortion resulting from channel coupling was reduced. (e.g. brass/drumus/guitar)
      # The q-2 new mode.
