 Not everyone wants ''vbr'' files. Therefore, the cbr structure is kept with the ''-b 192'' switch. Then mp3packer removes all MP3 errors but keeps it as a 192kbps cbr file. The finally resulting file after the mp3SX pass contains 32kbps surround info, is by 17% larger and reports itself as ''cbr 224kbps stereo MP3''.
-The alternative approach converts the file to vbr files with 15kbps surround info and an MP3 Surround file that is by 8% larger than the original stereo file. It reports itself as ''vbr 192kbps stereo MP3''.

 The choice of the above options depends on the value for "Smallest bitrate for CBR is <bitrate>" from the 1st pass of mp3packer. If it is one of 128, 160, 192, 224, or 256, then the second option is probably the right one for the 2nd pass.

 Apart from [[MP3packer]] as a program to repair and to modifiy the structure of MP3-files, at least another tool exists that modifies MP3 files (without decoding) to provide some "added value". The tool in question is [[MP3Surround | MP3SX]], a tool that extracts the ambience from already existing stereo [[MP3]]-files and dispatches the full stereo content to 5.1 speakers.

-Large [[MP3]] files, such as DJ mix sets obtained over the internet via P2P or by internet streaming are usually not error-free: they often have incomplete frames, sync errors, or come as ''vbr''-encoded files while the cue-sheet creation or the CD burning program requires ''cbr''-encoded MP3 files. The solution to all this is [[MP3packer]]. It always corrects all MP3 errors it can find.
