# 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.
