the info of audio i seen i your software may be incorrect.. i attach 3 image files.
first one show info of mp3 audio from mediaInfo.
second show info of same mp3 file from mp3 tag software.
third one show info of same file according to windows.
in these three file the value of bit rate is correct but unit (kpbs) is different.
MediaInfo shows Kbps (capital k)
while the other two shows kbps (small k)
actually i don't know what unit is correct but it may be bug.
