-Use this [http://archive.is/XXc3O WAV File Format Header Specification] and you'll be able to determine the ordering and size of the 16 bytes from "Audio Format" to "Bits per Sample per Channel" are identical. This makes up most of the WAV header data (apart from file and chunk size which cannot be determined from here) and can be directly transplanted to make extraction easier. Note that the MxCh header contains a few more bytes after this and therefore its "Sub-Chunk Size" is larger than the average WAV file's. These extra bytes should be ignored and not transplanted, though if they are the "Sub-Chunk Size" should be translated too (or at least increased to accommodate for them).
