Here it is. The reason for this wiki. The third generation shuffle iTunesSD format.< br >
Just like in the iTunesDB the default size for integer numbers seems to be 32 bit. In earlier iTunesSD files it was a rather odd 24 bit.< br >
Like the iTunesDB new third generation shuffle's iTunesSD is little endian. Earlier iTunesSD files were big endian.< br >
< br >
Little endian means that the numbers start with the lowest byte. So a value of 0x12345678 (decimal 305419896) will be written in the iTunesSD file as 78 56 34 12.< br >
Apparently the apple developers liked to look at their files with a hex viewer to. At least they choose the magic numbers for their headers in a way that their ASCII representation tells you its purpose. So the database header starts with a magic number 0x73686462 (dec. 1936221282). Not an easy number to remember. But translating those bytes one by one into ASCII you get "s" "h" "d" "b", which to me looks like "shuffle database". The little endian storage format changes the byte order so that the first characters of the new iTunesSD are in fact "bdhs", but now you know how we came up with the names for those separate elements.< br >
< br >
Here's the general layout of an iTunesSD file:< br >
