vbrfix - fix erroneous VBR MP3 files SYNOPSIS
vbrfix -flag1 -flag2 -flagn in.mp3 out.mp3 DESCRIPTION
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 SEE ALSO

ripperX -- graphical (GTK) frontend for ripping and OGG/FLAC/MP3 encoding CD tracks SYNOPSIS
This manual page documents briefly the ripperX command. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page. ripperX is an X-based program that uses cdparanoia to convert (i.e. "rip") CD audio tracks to WAV files, and then calls the Vorbis/Ogg encoder oggenc to convert the WAV to an OGG file. It can also call flac to perform loss-less compression on the WAV file, resulting in a FLAC file. Alternately, if you have an MP3 encoder installed such as toolame lame or bladeenc, it can then convert the WAV into a MP3 file. Besides a nice GUI interface, ripperX also supports CDDB queries to retrieve song and album information, progress meters, and pausing while ripping. OPTIONS
This program takes no command line arguments. After starting the application, select the Config button and cycle through the tabs to learn what options are configurable. Because Vorbis/Ogg typically uses variable bit rates, there is not a direct correlation between the bitrate selected for encoding and the rate used by oggenc. The bitrates selected in the MP3 tab of the Configuration dialog are passed to oggenc with the -b switch. Enabling or disabling VBR when using Vorbis/Ogg has no effect on the encoding process. The FLAC encoding currently does not accept any bitrate arguments, so any bitrate you specify in the config dialog will be ignored for this type of encoding. SEE ALSO
