INVALID CDs AND OVERLOADED TRACKS

Some invalid CD's tracks can not be ripped properly with cdparanoia.  In
such a case use cdda2wav ripper which uses less restricted error tests.  The
resulting MP3 files may be incorrect however.

The MP3 files made with lame use by default joint-stereo mode despite the
claim that lame uses stereo mode for higher quality files:

    Joint-stereo is the default mode for stereo files with VBR when -V is
    more than 4 or fixed bitrates of 160kbs or less.  At higher fixed
    bitrates or higher VBR settings, the default is stereo.

Such files can not be processed with mp3gain program decreasing or
increasing the gain for the separate channels.

The cdwrite repairs that using stereo mode for MP3 files using variable
bitrates or the constant bitrates starting from 192.

So if your normalized MP3 files are overloaded prepare them using these high
quality bitrates and then try to lower the gain starting from -1 dB.  Before
lowering the gain normalize the album in order to restore the proper basic
gain.

In order to reverse that change restore the previous gain.  Let us assume
that you used -1 dB correction for five times one by one.  So you lowered
the gain by -5 dB.  In order to restore the previous gain use +5 dB
correction or +1 dB correction five times.
