       vbrfix - fix erroneous VBR MP3 files


       vbrfix -flag1 -flag2 -flagn in.mp3 out.mp3


       In  an  average  song  there  are  points that require high quality and
       points that require low quality (i.e., silence). Instead of having  the
       whole  file  at  160kbps  (CBR  -  Constant Bit Rate), we can use VBR -
       Variable Bit rate. This allows us to have  say  96Kbps  at  points  not
       requiring  high  quality  and  192kbps when we need it: resulting in an
       overall smaller but higher quality MP3.

       However, the problem is that many MP3 programs estimate the time  of  a
       MP3 based on the first bitrate they find and the filesize. With VBR you
       can get fairly random times; as  most  songs  start  with  silence  you
       usually  get  the song length being shown as much longer than it should
       be. Also when you jump through the file in VBR: 50% through the file is
       not 50% through the song.

       A VBR null frame is placed at the beginning of the file to tell the MP3
       player information about the song length and indexing through the song.
       Some poor encoders don't produce this null frame or do so incorrectly -
       this is what vbrfix attempts to fix. Vbrfix can also fix other problems
       with  MP3s as it deletes all non-MP3 content (other than tags you state
       you want to keep).

       It can also help when merging two VBR MP3s together with a merging tool
       and then needing a newly calculated VBR null frame.

       -ri1          removeId3v1 Tag

       -ri2          removeId3v2 Tag

       -skiplame     if a tag was made by LAME don't fix it

       -always       always write a new file even if not VBR

       -makevbr      make it VBR (you need -always also)

       -log          write a log file

       -lameinfo     keep the lame info
