mp3recovery
mp3recovery extracts mp3 files from files/devices, e.g. images of broken mp3 players or disks. It preserves tag informations (id3v1, id3v2) and stores the recovered files in subdirectories like "interpret/album/title.mp3", if id3v1 tags are present. If not, files get sequential numbers (e.g. 217.mp3).
You can use this tool when your mp3 players/disks file system/partition table/whatever is broken and you can't access your music normally any longer.
mp3recovery can handle huge amounts of data, a recovery of an 80gb iPod Classic (using an image on an external drive) took 3 hours and 50 minutes and recovered 9373 songs (45gb).
Usage
mp3recovery <file/device> [<offset>]
Just pass the path to an image (or directly to a device) and mp3recovery will start working. If you stopped at a certain point and want to continue the recovery, append the according offset (this tool will print its current offset every 100mb). Files smaller than 500kb and bigger than 15mb are ignored, you can change these values in the source code.
The following example shows operation on a fake image I generated using data from /dev/urandom, placing three MP3 files in between.
