Loud albums problems, Normalization as alternative

Hi for all, i am new in this community; i love the music and the transparent reproduction of audio. My native language is spanish; excuse me my bad english.
I read many of the forums in this community and are very interesting  .

I encode many albums with CDex 1.51 & Lame 3.96.1 (-V1 -b32 -h --lowpass 20),
the sound is very good.. very clear and transparent (for my ears), but the problem for me is the loud albums  , because the dynamic range is very low  and the music is near for 0 db!! (100 %), and the resulting mp3 is very distort and clipping... offensive for any ears  . I believe one alternative solution for this problem: the CDex have one function for normalization, i test this settings:

Normalize:  ANY  if signal is <  0%  (1)
   
                  85%  if signal is >  85% (2)

the setting (1) is disabled (0%); and the setting (2) is enable only if the maximum peak of the song is > 85%; if the maximum peak of the song if < 85% the song is not normalize.
I test for many albums and not clipping mp3's    ; for very loud albums (for example: lenny kravitz - greatest hits) i test 80% with good results.. please any comments and other alternatives i appreciated

MP3Gain

It will make the songs the same overall loudness instead of just looking at peaks.

Ok, thank you; i check this program but this normalizes the sound directly in the final mp3; one question.. this MP3Gain fixes the clipping problems for distorted mp3's?

If the distortion was present in the original CD, then nothing can be done about it. If the clipping was added by the MP3, then MP3Gain will probably help.

Another option is to use a player such as Foobar2000 which supports replaygain.

Many thanks.... What is exactly REPLAY GAIN?

Replaygain is a program which scans a song and calculates how loud it sounds, then writes a tag to the file telling the player to change the volume by a certain amount to make all music average about the same volume. Foobar2000 is the only media player I know of which supports it. The advantage over MP3Gain is that the actual file isn't changed, only a tag is written to the file.

in_mpg123 for Winamp support mp3 ReplayGain.  The default in_mp3.dll does not.  Foobar is the only player to support mp3 ReplayGain stock however.
