RAW audio files

I extracted audio files from Heroes IV video game. But they all RAW and every file has own format: some 8-bit, some 16-bit unsigned, some 16-bit signed big-endian. Are there a way to guess audio format from content? Preferably non-calculus based.

Why can't you just see what is the format game loads? It probably has a routine or list where all files are labeled with their format code.
