MP3optimized
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.
Apart from such 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 MP3SX, a tool that extracts the ambience from already existing stereo MP3-files and dispatches the full stereo content to 5.1 speakers.
Both tools together allow extensive manipulation of stereo MP3 files (without decoding them)to optimize and to upgrade existing stereo MP3-files to MP3Surround files that can be played by any software and hardware player.
