[edit] Identification
Files begin with 52 49 46 46 which in ASCII is "RIFF", and have 73 66 62 6b or in ASCII "sfbk" at offset 8.
In most cases, this is followed by "LIST" at offset 12, "INFOifil" at offset 20, and bytes 02 00 at offset 32. The last 02 byte distinguishes major version 2 from major version 1.
