Hi, not always I tag correctly the mp3 that i generate from my original CDs and I'm having a chaos in my media library. Could you please recommend me a good media library organizer with this features:
Hi. I actually think foobar2000 could preform all of these things, however, depending on the amount of automation you require you may or may not find it useful.

- Supports all variety of audio formats: MP3, MP4, WMA, FLAC, APE, WV, OGG, ...
as long as your WMA files aren't protected, yep.

- Detection and manually elimination of the duplicates using the tag information, the folder name and the file name, showing information of the files just like the bitrate of each file and its size.
You could sort a playlist by whatever criteria you want and find duplicates that way. Depending on the size of your library, this might even be faster than using one of the dedicated programs that does this.

- Detects if all the music files in a folder (album) have any problem with the tags: Not the same Artist, Album, Genre or Year. No Track order (if not could use the file name),...
This is something the Facets component is good at showing.
Also, using %path_sort% and a grouping pattern in the playlist can display discrepancies rather quickly.

- Detects tracks with its bitrate below a limiter (192kbps, for example)
add the bitrate column, load your entire library into the playlist, and click the bitrate column header.

- Fix files with invalid characters in its name or in the tags.
Something foobar's very good at. you can use the $ascii() command in a masstagger script or "Format form Other Fields..." and "Rename to..." dialogs to remove non-ascii characters.
---------------------------------
Another advantage foobar has is that it is blazingly fast at handling large quantities of files, especially once they are imported into the media library.
My experience with most dedicated tagging programs is that they are often stupidly slow, like doing something simple like browsing a different folder can require reloading that entire directories contents.
